{"product_id":"lehrer-quasar™-fern-green-quartz-14mm-roundfaceted-gemstone","title":"Lehrer Quasar™ Fern Green Quartz 14mm RoundFaceted Gemstone","description":"Developed by self-taught gem carver and visionary jewelry artist Glenn Lehrer, the Quasar™ cut further explores the possibilities of moving light within a gemstone. This special cut features a negative (inverted), faceted cone painstakingly carved into the back of the gemstone, similar to that of the TorusRing™ cut. In the Quasar cut, the table of the gemstone has a smooth, concave depression cut into the center. The negative space in the table creates a reflective effect on the light entering through the cone. The Quasar takes about five times longer to create than a traditional round gemstone. The result is well worth the time spent. As Glenn says, “I carve in light . . . bending light . . . turning each sparkling ray into an almost liquid medium.” The resulting look of the Quasar cut is reminiscent of the center of a radiant galaxy far away.\n\nRio Grande is the exclusive distributor of the Lehrer Quasar™ gemstone.\u003cbr\u003e\u003cul\u003e\n\u003cli\u003e\n\u003cstrong\u003eGemstone Type:\u003c\/strong\u003e Quartz\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eStone Shape:\u003c\/strong\u003e Round\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eStone Size:\u003c\/strong\u003e 14mm\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eStone Type:\u003c\/strong\u003e Natural\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eColor:\u003c\/strong\u003e Green\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eEnhancement:\u003c\/strong\u003e Diffusion (U)\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eMohs Hardness:\u003c\/strong\u003e 7\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eRefractive Index:\u003c\/strong\u003e 1.544–1.553\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eSpecific Gravity:\u003c\/strong\u003e 2.63–2.65\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eBrand:\u003c\/strong\u003e Quasar\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eWeight:\u003c\/strong\u003e 0.000 kg\u003c\/li\u003e\n\u003c\/ul\u003e","brand":"Amadesa","offers":[{"title":"Default Title","offer_id":50754910749018,"sku":"7841614","price":906.96,"currency_code":"ILS","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0934\/7897\/7882\/files\/7841614in.jpg?v=1742362952","url":"https:\/\/www.amadesa.com\/he-il\/products\/lehrer-quasar%e2%84%a2-fern-green-quartz-14mm-roundfaceted-gemstone","provider":"Amadesa","version":"1.0","type":"link"}
