The ones with great phosphorescence we also call 'Firefly Garnet'.\u003c\/p\u003e\n\u003cp\u003eThat's right, these particular examples glow in the dark!  They actually do their best to prevent that from happening because it makes them less effective for technical use, but every now and then growth goes wrong and a crystal will have some afterglow, and an even smaller percentage are also clean enough to facet into gems.\u003c\/p\u003e\n\u003cp\u003eGAGG is a durable gem with a high hardness of 8 and no cleavage.\u003c\/p\u003e","brand":"Turtle's Hoard","offers":[{"title":"Pendant with Round 'Dragon Eye' Cut avg. 10ct Stone  10mm","offer_id":49340604023072,"sku":"Pendant_GAGG","price":550.0,"currency_code":"USD","in_stock":false},{"title":"Pendant with Checkerboard Teardrop Cut avg. 7ct Stone 13x10mm","offer_id":49340604055840,"sku":"Pendant_GAGG","price":450.0,"currency_code":"USD","in_stock":false},{"title":"Pendant with Long Hexagon Cut avg. 7ct Stone 13x8mm","offer_id":49340604088608,"sku":"Pendant_GAGG","price":450.0,"currency_code":"USD","in_stock":false}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0753\/6794\/0384\/files\/glowinthedark.jpg?v=1728066646","url":"https:\/\/store.gemsofscience.com\/products\/green-glow-phosphorescent-gagg-pendants-lab-glowing-garnet","provider":"Gems Of Science","version":"1.0","type":"link"}
