{"product_id":"optical-sapphire-cores-and-wafers","title":"Optical Sapphire Discs, Cores and Wafers","description":"These are cores and wafers of colorless optical sapphire grown by Rubicon, one of the top US growers of sapphire, and purchased from a factory closing auction.  These are a mixture of rejected material (likely for surface chips or maybe minor optical misalignments) and cores\/wafers that just didn't get used before the factory closed.  These were grown for use in high end optics and as a substrate to grow bespoke computer chips on.  These can of course be faceted as gems and are just extremely cool!  A few have chips and\/or cracks and range in size from small pucks to large rods and cores.","brand":"Turtle's Hoard","offers":[{"title":"Disc 40-60g 5-8mm Thick 2in\/50mm Diameter","offer_id":48449640661280,"sku":"Sapphire_Core","price":30.0,"currency_code":"USD","in_stock":false},{"title":"Disc 60-100g 8-10mm Thick 2in\/50mm diameter","offer_id":46271973097760,"sku":"Sapphire_Core","price":40.0,"currency_code":"USD","in_stock":false},{"title":"Core 100-200g 2in\/50mm diameter","offer_id":46271973130528,"sku":"Sapphire_Core_100","price":55.0,"currency_code":"USD","in_stock":false},{"title":"Core 200-300g 2in\/50mm diameter","offer_id":46271973196064,"sku":"Sapphire_Core_200","price":105.0,"currency_code":"USD","in_stock":true},{"title":"Core 300-400g 2in\/50mm diameter","offer_id":46271973228832,"sku":"Sapphire_Core_300","price":120.0,"currency_code":"USD","in_stock":true},{"title":"Core 400-500g 2in\/50mm diameter","offer_id":46271973261600,"sku":"Sapphire_Core_400","price":210.0,"currency_code":"USD","in_stock":true},{"title":"2850g Giant Sapphire Core 4.5in\/115mm diameter 69mm thick","offer_id":46271973425440,"sku":"Sapphire_Core","price":1600.0,"currency_code":"USD","in_stock":false},{"title":"580-590g Rods 1.4in\/37mm diameter 135-150mm long","offer_id":46271973294368,"sku":"Sapphire_Core","price":650.0,"currency_code":"USD","in_stock":false},{"title":"1640g Rod 2in\/50mm diameter 190mm long","offer_id":46271973327136,"sku":"Sapphire_Core","price":950.0,"currency_code":"USD","in_stock":false},{"title":"40g Wafer 3.3in\/84.5mm diameter 1.6-1.8mm","offer_id":46271973359904,"sku":"Sapphire_Wafer","price":30.0,"currency_code":"USD","in_stock":false},{"title":"80g Wafer 3.3in\/84.5mm diameter 3.6mm","offer_id":46271973392672,"sku":"Sapphire_Wafer","price":60.0,"currency_code":"USD","in_stock":false}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0753\/6794\/0384\/files\/front4.jpg?v=1697522886","url":"https:\/\/store.gemsofscience.com\/products\/optical-sapphire-cores-and-wafers","provider":"Gems Of Science","version":"1.0","type":"link"}
