We have calibrated rounds, squares and trillions, as well as individual fancy cut stones.  Each fancy cut stone has its own individual photo and they can be purchased individually. The variation dropdown shows the carat weight and measurements of each stone, with the individual fancy cuts at the bottom below the calibrated cuts.\u003cbr data-mce-fragment=\"1\"\u003e\u003cbr data-mce-fragment=\"1\"\u003eLuAG is an exotic lab-created crystal with the same structure as natural garnets, but a composition and properties which are impossible in nature, particularly its outrageously strong green fluorescence which makes it glow when exposed to sunlight and even some indoor light. This is what we call a 'lumogarnet' - a lab created garnet with incredible fluorescence, designed to help detect invisible radiation. This is one of my favorite synthetic materials--brilliant and hard enough for use in all jewelry (mohs 8.5!).\u003cbr data-mce-fragment=\"1\"\u003e\u003cbr data-mce-fragment=\"1\"\u003eThe fluorescence really is crazy--even normal room lights will make a LuAG gem fluoresce, and outdoors with indirect sunlight can make it look like it is photoshopped into real life. A blacklight aimed directly at it makes it insanely bright. It is just a great material overall, perfect for the collector and jeweler alike.\u003c\/p\u003e","brand":"Turtle's Hoard","offers":[{"title":"2mm Round (avg.

Like normal Cr YAG (aka Christmas Garnet) it has a super rich green base color, but the addition of thulium takes the energy from the chromium atoms, splits it into two pieces, and sends it to the holmium atoms for the final infrared emission. Since the chromium's energy has been taken, it no longer glows red, and the base color is a richer and purer pine green. Like all YAG, CTH has excellent brilliance, and with a hardness of 8.5 is great for use in all kinds of jewelry.\u003c\/p\u003e\n\u003cp\u003eCTH YAG is used in far infrared lasers for a variety of

so much of what we get is from old stock.  Some rutile is golden, some light yellow and it can very occasionally be a lighter blue or blue-yellow bicolor--all of them are absolutely stunning once

Lighter toned stones will look almost pure green when placed on a white background but change to a mix of red and green when put on a dark background. Note that the camera exaggerates the red at the expense of the green--they do look better in person. They look a bit like alexandrite or color change garnet but is also totally different and unique.

allow for a 365 degree view in a wide spectral range.  With the incredible accelerations and speed that have to be withstood an ultra hard, ultra durable material like sapphire is needed.  But how do

shattered during growth or usually all three.  They recently closed their factory in Chicago and auctioned off the contents, and we were able to buy the entire pile of defective crystals!  It was a

It was briefly used as a diamond simulant and marketed as 'tantalia', but was never very successful- tantalate is much brighter and more dispersive than a diamond,so there was an obvious difference when cut. Faceted lithium tantalate gems give off brilliant rainbows of color, so it's an amazing gem in its own right instead of just trying to imitate diamonds.\u003c\/p\u003e\n\u003cp\u003eNote that LiTAO3's hardness is just under 6, which makes it harder than some other classic diamond simulants (like lithium niobate and strontium titanate) but still soft for a gem, a little softer than tanzanite.

in the Dark GAGG Lumogarnet Facet Rough \"Long Glow\"!!","description":"\u003cp\u003eThese are lab-created GAGG (Gadolinium Aluminum Gallium Garnet) facet rough with pronounced phosphorescence (glow in the dark). Each piece is marked with its weight and you select which one to purchase.\u003c\/p\u003e\n\u003cp\u003eNote that, as a particularly defective crystal, some of these pieces will have a few bubbles.  The bubbles tend to correlate with the highest afterglow.\u003c\/p\u003e\n\u003cp\u003eThis is \"Long glow\" or \"high glow\" GAGG--a type of defective GAGG which exhibits a glow-in-the-dark effect.  They work pretty hard to avoid this happening since it makes the crystal useless for its intended purpose (detecting invisible radiation).  However mistakes happen and sometimes a crystal does show this effect.  Each one is a little different because the causes can vary, but this crystal shows a bright but short-lived initial glow which fades to a dimmer but long-lasting glow.  It was visible after at least an hour of sitting on my bedside table in the dark.\u003cbr\u003e\u003cbr\u003eCerium GAGG is brand new as far as gems go--it only entered industrial usage in 2014, and we just introduced it to the gem market last year. It is what we call a 'lumogarnet' - an exotic lab-created garnet with incredible fluorescence. We also call this 'Firefly Garnet'.\u003c\/p\u003e\n\u003cp\u003eLike Ce:YAG and LuAG GAGG is used as a scintillator, a crystal grown for its insanely strong fluorescence.  It is used to help detect invisible radiation by absorbing it and converting it to easily-detected visible light--gamma rays and x-rays will activate its glow in addition to UV and even normal blue light.\u003c\/p\u003e\n\u003cp\u003eProperties-wise this material is like an upgraded version of the classic GGG crossed with an aluminum garnet (like YAG and LuAG) to give it excellent hardness (8) while maintaining a high RI (1.9) and generally excellent gem properties. This material has very bright fluorescence, and like Ce:YAG and LuAG it is used as a scintillator to help detect invisible radiation.\u003c\/p\u003e","brand":"Turtle's Hoard","offers":[{"title":"1pc

individually.\u003c\/span\u003e\u003c\/p\u003e\n\u003cp\u003eCr:YAG, aka 'Christmas garnet' is an exotic lab-created garnet and a really unique gem even by our standards. It has a totally unique color, with a rich almost tsavorite green base and strong red fluorescence. This means that it shows a mixture of red and green flashes, and which color predominates depends on the lighting (color and angle) as well as the background it is set against. Lighter toned stones will look almost pure green when placed on a white background but change to a mix of red and green when put on a dark background. Note that the camera exaggerates the red at the expense of the green--they do look better in person. They look a bit like alexandrite or color change garnet but is also totally different and unique. This is easily one of my favorite gems, unlike anything else found in nature or any other synthetic.\u003cbr\u003e\u003cbr\u003eCr:YAG is used in lasers as a 'q switch', which means it is opaque until it absorbs a critical amount of radiation and then suddenly becomes transparent. This allows a laser to charge its crystal up to a higher energy level before suddenly releasing it all in a single powerful\u003cspan\u003e \u003c\/span\u003eburst instead of shooting out in a continuous beam. Pulsed lasers can be extremely powerful and are incredibly useful for all sorts of applications, from tattoo removal to cutting edge physics research. Basically, like all bad sci-fi and good RPGs you can upgrade your laser just by slapping a crystal on the end.\u003cbr\u003e\u003cbr\u003eLike all YAG this material is ideal for jewelry with a high

Rod Alexandrite Facet Rough Lab Created Crystals","description":"\u003cp\u003eThese are genuine, lab-created alexandrite facet rough.  These pieces were sawn from laser rods, either during initial production or refurbishment efforts (don't worry, no laser-grade rods were harmed in the making of this rough!)\u003cbr\u003e\u003cbr\u003eWe recently got our hands on a few decommissioned rods of alexandrite from lasers! These rods likely lived out a full career inside lasers as a crystalline lasing medium, but eventually they were pushed too far or had dust land in the wrong spot and the ends blew off, rendering them inoperable.  In these cases the rods can sometimes be sawn and repolished, leaving pieces that are now usable for gems.  These may have also been removed during the initial production of the laser rods before they were used.  Either way, now they get to live out their retirement as gemstones! While they may have been designed for science they make amazing gems as well. They have a strong color change from blue-green to purple-pink and better yet often show flashes of both in mixed lighting when cut--the camera struggles to capture this, especially the green colors. On top of that they also show rich red fluorescence which affects their color, and the angle of lighting will also cause differences in color because this material is strongly trichroic.\u003cbr\u003e\u003cbr\u003eAlexandrite is the color-changing chromium-bearing variety of chrysoberyl, and it has been a popular gem since the first natural deposits were discovered in Russia. Its high hardness (8.5) and durability make it suitable even for ring wear, and that along with its incredible combination of colors has made it a classic. The only thing holding it back is its rarity. Oddly enough even lab-created alexandrite is quite uncommon. Synthetic alexandrite is mostly grown for industry, where it is used in some particular high-end laser systems, and the process to grow it is very expensive. Very little is produced anymore, and even when it was produced it was uncommon on the gem market. Usually instead lab-created sapphire with a color change effect was sold as alexandrite, but that material really can't hold a candle to alexandrite.\u003cbr\u003e\u003c\/p\u003e","brand":"Turtle's

\u003c\/span\u003e\u003c\/span\u003ebut the shape really isn't conducive to larger flat shapes.\u003c\/p\u003e\n\u003cp\u003eTo solve this problem Rubicon, at the time one of America's greatest sapphire growing companies, got a 5 million dollar grant to develop the LANCE furnace, an ultra high tech crystal growing machine that grows the world's largest flat sapphires via the \"boat\" method aka HDSM.  If you've ever been to a Quiznos think of the ovens with a conveyer belt they use to toast subs evenly--it's basically that but with a giant flat pan of molten, crystallizing sapphire.\u003c\/p\u003e\n\u003cp\u003eThough the LANCE is absolutely incredible (we got to see it in person and meet the head crystal grower!!) it didn't have a 100% success rate, and over time the company built up a pile of defective sapphire crystals that had either been contaminated with titanium (which turns them pink and ruins UV transmission), developed bubbles, shattered during growth or usually all three.  They recently closed their factory in Chicago and auctioned off the contents, and we were able to buy the entire pile of defective crystals!  It was a dream come true!\u003cbr\u003e\u003c\/p\u003e","brand":"Turtle's Hoard","offers":[{"title":"EOTS Cut, ~5x3.7mm, avg.

It has the same structure as a natural garnet, but has a composition that would never be possible in nature. The result is a bright and very dispersive gem with optical properties similar to diamond (cubic crystal structure with a lower RI but the same dispersion as diamond), giving it incredible brilliance and fire. It is not, however, grown for gem usage at all, but because of its incredible ability to act as a Faraday rotator. Light passing through TGG in the presence of a magnetic field has its polarization rotated, which might not sound that interesting but is incredible useful for lasers. Lasers shoot out powerful beams but are very fragile, and if any of the light bounces back at them it can quickly burn them out. With TGG it is possible to make a high-efficiency optical isolator that prevents any of that sort of backsplash. This is likely the first time it has ever been faceted as a gem, and if not it is close.\u003c\/span\u003e\u003cbr\u003e\u003cbr\u003e\u003cspan\u003eIt also has bright green fluorescence under 365nm

Cut F-35 Window Sapphire Rings in Sterling Silver (F35 Gem)","description":"\u003cp\u003e\u003cspan data-mce-fragment=\"1\"\u003eThese are lab created sapphires which were grown for use as a sensor window in the F35 fighter jet but didn't meet spec.  They've been faceted and set in solid sterling silver rings!\u003c\/span\u003e\u003c\/p\u003e\n\u003cp\u003eNote these stones glow blue under shortwave UV because of titanium contamination.\u003cbr data-mce-fragment=\"1\"\u003e\u003cbr data-mce-fragment=\"1\"\u003eThis is a really cool material--lab sapphire grown for windows on the F35!  These aren't used on the cockpit but on a sensor array right below.  There are numerous sensors on the bottom of an F35 that allow for a 365 degree view in a wide spectral range.  With the incredible accelerations and speed that have to be withstood an ultra hard, ultra durable material like sapphire is needed.  But how do you make giant, flat sheets of sapphire?  Normally you'd cut windows out of a big round boule grown by HEM or kyropolis but the shape really isn't conducive to larger flat shapes.\u003c\/p\u003e\n\u003cp\u003eTo solve this problem Rubicon, at the time one of America's greatest sapphire growing companies, got a 5 million dollar grant to develop the LANCE furnace, an ultra high tech crystal growing machine that grows the world's largest flat sapphires via the \"boat\" method aka HDSM.  If you've ever been to a Quiznos think of the ovens with a conveyer belt they use to toast subs evenly--it's basically that but with a giant flat pan of molten, crystallizing sapphire.\u003c\/p\u003e\n\u003cp\u003eThough the LANCE is absolutely incredible (we got to see it in person and meet the head crystal grower!!) it didn't have a 100% success rate, and over time the company built up a pile of defective sapphire crystals that had either been contaminated with titanium (which turns them pink and ruins UV transmission), developed bubbles, shattered during growth or usually all three.  They recently closed their factory in Chicago and auctioned off the contents, and we were able to buy the entire pile of defective crystals!  It was a dream come true!\u003cbr data-mce-fragment=\"1\"\u003e\u003cbr data-mce-fragment=\"1\"\u003e\u003cspan data-mce-fragment=\"1\"\u003e1023\u003c\/span\u003e\u003c\/p\u003e","brand":"Turtle's

Soviet Laser Garnet, Faceted YAG Loose Gemstones","description":"\u003cp\u003e\u003cspan\u003eThese are faceted Er+Nd:YAG (Yttrium Aluminum Garnet) from an old Soviet collection.\u003c\/span\u003e\u003c\/p\u003e\n\u003cp\u003e\u003cspan\u003eThis is a new material for us from an old collection, a 40-year-old failed experimental laser garnet from the Soviet Union. It is clearly doped with Erbium, and like our modern pure Er:YAG it has a striking combination of orange and pink colors and a remarkable color change. Unlike pure Er:YAG it has a stronger pink component, suggesting the addition of another dopant like Nd, and the color is also somewhat lighter as well. Most of the material was grown via HDSM aka the 'boat method', which was favored in the Soviet Union for most non-quartz growth, though a few pieces were clearly Czochralski pulled. From doing further reading we learned that the inventor of the HDSM method, Bagdasarov, was a soviet scientist and was working on erbium yag laser material in the 80s, so it all seems to check out.  Codoping Nd and Er can apparently produce a laser with a dual wavelength output which is incredibly useful so it all kind of checks out.  We even have a good guess as to why this material didn't make the cut for scientific use--aside from the variable base color some larger pieces show noticeable color zoning which means the codopants were not evenly mixed, which is not great if you want to make a laser.  While material intended for gem usage was also grown in these labs it would be odd to mix these two elements for that purpose and odder yet to then discard perfectly gem-quality material, so while we don't have perfect provenance the available information seems to match what the seller told us.\u003c\/span\u003e\u003cbr data-mce-fragment=\"1\"\u003e\u003cbr data-mce-fragment=\"1\"\u003e\u003cspan\u003eOverall, it's a really cool material, and while I'm sure they were frustrated by the production problems their loss is our gain.

It is clearly doped with Erbium, and like our modern pure Er:YAG it has a striking combination of orange and pink colors and a remarkable color change. Unlike pure Er:YAG it has a stronger pink component, suggesting the addition of another dopant like Nd, and the color is also somewhat lighter as well. Most of the material was grown via HDSM aka the 'boat method', though a few pieces were clearly czochralski pulled. From doing further reading we learned that the inventor of the HDSM method was a soviet scientist and was working on erbium yag laser material in the 80s. Codoping Nd and Er can produce a laser with a dual wavelength output as well, so that was likely the reason they grew it.  We even have a good guess as to why this material didn't make the cut--aside from the variable base color some larger pieces show noticeable color zoning which means the codopants were not evenly mixed, which is not great if you want to make a laser.\u003cbr\u003e\u003cbr\u003eOverall, it's a really cool material, and while I'm sure they were frustrated by the production problems their loss is our gain. This cuts amazing gems with a rich peachy-pink color-changing padparascha-like color.

Emerald Faceted Stones, Hydrothermal Emerald Gems","description":"\u003cp\u003eThese are lab created emeralds cut in a variety of calibrated sizes.  Some stones have minor cracks and inclusions, similar to a natural emerald, due to the hydrothermal growth method (or possible flux--some of these have inclusions that look more like flux growth).\u003c\/p\u003e\n\u003cp\u003eEmerald is one of the most classic gems, right up there with ruby and sapphire, but unlike them it is very difficult to grow in the lab.  It can't be made by flame fusion or pulling methods, leaving the flux (slow and expensive and poisonous) and hydrothermal (slow and expensive and potentially explosive) methods.  Still, it compensates for that with its incredible green color.\u003c\/p\u003e\n\u003cp\u003eThis one is a bit unusual for us since it wasn't grown for science.  We got these from a friend's old collection (something that was in the back of his safe for decades).  They might have been grown by an Australian maker but we aren't sure about that. \u003c\/p\u003e\n\u003cp\u003eOccasionally lasers are made using an emerald crystal rod.  The papers always have justifications about it being a good

While material of this color would be called 'pink sapphire' in a gemological context, in laser science all corundum doped with chromium is considered ruby (in contrast to pink laser sapphire which is doped with titanium). In a laser this material would be cut into a cylinder, charged up with photons from the sides and emit a beam of coherent light out of the end--in fact the very first laser was built with a ruby. As you would expect for this requires a very high standard of chemical purity and structural perfection--when energizing a crystal imperfections tend to heat up and explode. Czochralski pulling ensures that these stones have perfect crystal structure, high chemical purity and strong, even coloration, which coincidentally makes them exceptional for gem usage as well.\u003cbr data-mce-fragment=\"1\"\u003e\u003cbr data-mce-fragment=\"1\"\u003eBack in the 80s the US government spun up the SDI (Strategic Defense Initiative) program, the idea being to create powerful defenses against nuclear weapons using whatever wacky sci-fi ideas people could come up with--because of this the media often called it the 'Star Wars' program. One idea was to make powerful lasers that would shoot missiles right out of the sky en route, and because of that they grew a lot of laser ruby and stockpiled it for future use. When the SDI was finally wound down there was a lot of this stuff lying around which was surplused off and often made it into the hands of faceters. Unfortunately I missed out on all of that on account of being born that year, but we've been able to buy a few old collections that contained some of this material. We can't be 1000% certain of the provenance because it wasn't specifically labeled as government material but it was labeled as laser ruby and is from exactly the right time so I would call it 99% certain. \u003cbr data-mce-fragment=\"1\"\u003e\u003cbr data-mce-fragment=\"1\"\u003eThis material cuts super bright, neon pink stones with a ton of scintillation and super bright fluorescence which gives them an extra pop.

This means that depending on the application you might see crystals that only have Nd or ones that are almost entirely Ce with just a pinch of Nd.  Pure Nd gives a color shifting purple-pink color while pure Ce gives a rich fluorescent yellow color--when the two are mixed you get an unusual pink, peach or golden yellow color depending on proportions that shifts depending on the lighting.  These stones also show unusual dual fluorescence, with a mix of bright yellow and pink under shortwave UV and yellow-green under both blue light and shortwave UV.\u003c\/p\u003e\n\u003cp\u003e\u003cspan style=\"font-size: 0.875rem;\"\u003eCTH YAG is used in far infrared lasers for a variety of purposes including medical procedures and meteorological measurements.  \u003c\/span\u003eLike normal Cr YAG (aka Christmas Garnet) it has a super rich green base color, but the addition of thulium quenches the fluorescence, allowing it to be absorbed by the holmium instead of released as red light.
