{"title":"Bulgarian Quartz","description":"\u003cp\u003eQuartz is silicon dioxide (SiO\u003csub\u003e2\u003c\/sub\u003e), the second most common mineral in the Earth's continental crust after feldspar. It crystallises in six-sided prisms that end in pointed tips and comes in more colours and forms than almost any other mineral: amethyst, citrine, smoky and rose quartz are all quartz, and so are chalcedony, agate and jasper, which are made of crystals too small to see. With a hardness of 7 it scratches glass, and because it produces a small electric charge under pressure, thin quartz plates keep time in watches and electronics.\u003c\/p\u003e\u003ch3\u003eBulgarian quartz\u003c\/h3\u003e\u003cp\u003eThe quartz in this collection comes from Bulgaria. Many Bulgarian specimens come from the lead-zinc deposits of the Rhodope Mountains in the south of the country, where hot, mineral-rich fluids moved through cracks in the rock and slowly cooled, leaving crystals behind. You will find milky white crystal groups, coloured by countless tiny fluid bubbles inside the crystals; sugar quartz, the collectors' name for crusts of very small, glittering crystals; rusty quartz, coated orange by a thin layer of iron oxide; and grey chalcedony with sparkling druzy quartz on top.\u003c\/p\u003e\u003ch3\u003eOther minerals in these specimens\u003c\/h3\u003e\u003cp\u003eQuartz rarely grew alone in these veins.

The piece comes from the Krushev dol mine in the Madan ore field of the Rhodope Mountains, one of the Bulgarian lead-zinc workings that supplies most of the country's collector minerals. It is untreated, exactly as it came out of the ground. Quartz sits at 7 on the Mohs scale and calcite at 3, so the calcite blades are the delicate part of the piece, which makes it best suited to a display shelf or a UV cabinet.\u003c\/p\u003e\u003cul\u003e\n\u003cli\u003e\n\u003cstrong\u003eStone type:\u003c\/strong\u003e Natural sugar quartz with calcite\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eWeight:\u003c\/strong\u003e 78.5g\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eSize:\u003c\/strong\u003e 60x39x25mm\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eColor:\u003c\/strong\u003e Pale grey and white\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eFluorescence:\u003c\/strong\u003e Calcite reacts under UV\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eCut:\u003c\/strong\u003e Rough\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eClarity:\u003c\/strong\u003e Opaque\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eTreatment:\u003c\/strong\u003e Untreated\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eOrigin:\u003c\/strong\u003e Krushev dol mine, Bulgaria\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eHardness:\u003c\/strong\u003e 3-7 (Mohs)\u003c\/li\u003e\n\u003c\/ul\u003e\u003cp\u003eNatural sugar quartz with fluorescent calcite, Krushev dol mine, Bulgaria, single piece.\u003c\/p\u003e","brand":"Lapis Magica","offers":[{"title":"Default Title","offer_id":55406349943109,"sku":"bg078-1-2","price":5.1,"currency_code":"EUR","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0968\/8576\/8517\/files\/bulgarian-sugar-quartz-with-fluorescent-calcite-78g.jpg?v=1756321045"}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0968\/8576\/8517\/collections\/quartz-crystal-cluster-from-bulgaria-501g.jpg?v=1792501424","url":"https:\/\/lapismagica.com\/collections\/bulgarian-quartz.oembed","provider":"Lapis Magica","version":"1.0","type":"link"}
