Iron, manganese, or tiny mineral inclusions can impart shades ranging from pale champagne to deep smoky brown. \u003c\/p\u003e\n\u003cp\u003eDonghai Mine, Jiangsu Province, China, is located within the Sulu ultrahigh-pressure metamorphic belt, one of the world's most geologically significant regions. Formed during the collision of two ancient continental plates hundreds of millions of years ago, the area contains rocks that were buried deep within the Earth before being uplifted to the surface. Later hydrothermal activity deposited mineral-rich veins throughout the region, creating exceptional crystals of quartz, fluorite, calcite, and other minerals.\u003c\/p\u003e\n\u003cp\u003eToday, Donghai is internationally recognized as one of China's premier mineral-producing districts. In addition to quartz, the district is well known for its beautifully crystallized fluorite and calcite, valued for their vibrant colors, transparency, and excellent crystal form. Specimens from Donghai are prized not only for their beauty but also for the remarkable geological history they represent.\u003c\/p\u003e\n\u003cp\u003e\u003cstrong\u003eName\u003c\/strong\u003e:  Smoky Calcite Cluster \u003cbr\u003e\u003cstrong\u003eSpecimen Size: \u003c\/strong\u003e  Large Cabinet\u003cspan\u003e-\u003c\/span\u003eSized \u003cbr\u003e\u003cstrong\u003eDimensions\u003c\/strong\u003e:  235x150x100 mm \/ 9.3x5.9x3.9 inches \u003cbr\u003e\u003cstrong\u003eWeight\u003c\/strong\u003e:  1.885 Kg \/ 4.15 pounds\u003cbr\u003e\u003cstrong\u003eLocation\u003c\/strong\u003e:   \u003cspan style=\"font-size: 0.875rem;\"\u003e\u003cspan\u003eDonghai Mine Jiangsu Province, China\u003c\/span\u003e\u003c\/span\u003e\u003c\/p\u003e\n\u003cp\u003e \u003c\/p\u003e","brand":"Canagem.com","offers":[{"title":"Default Title","offer_id":47887451226365,"sku":"02-01082","price":375.0,"currency_code":"CAD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0053\/3309\/0374\/files\/20260725_113645.jpg?v=1784998902","url":"https:\/\/canagem.com\/products\/natural-smoky-calcite-crystal-cluster-1-885kg-donghai-jiangsu-sheng-china","provider":"Canagem.com","version":"1.0","type":"link"}
