Green is the most commonly found diopside color, which gets its beautiful hue from traces of the element chromium; hence the name chrome diopside. This chromium-rich diopside is transparent to translucent in appearance with a good chance of high visual clarity. The most valuable chromium diopside gems have a deep forest green similar to tsavorite garnet.\nWhile chrome diopside is not difficult to come by, medium green stones over 2 carats are incredibly rare as the larger the stone the darker it tends to be, even appearing nearly black. Chrome diopside does not receive enhancements to increase color or clarity, making it a naturally lovely untreated stone option for jewelry.\n\nMineral Information\tCalcium magnesium silicate\nChemical Composition\tCaMgSi2O6\nColor\tGreen, yellow, colorless, brown, black\nHardness\t5 to 6 (Mohs)\nSpecific Gravity\t3.22 - 3.38\nRefractive Index\t1.664 - 1.730","brand":"ilovecrystalsandgems","offers":[{"title":"Default Title","offer_id":41645073465391,"sku":"#1-GEM-M-DP-1","price":129.99,"currency_code":"CAD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0575\/8513\/9759\/files\/3d996bc0-f3ef-4e05-a634-4868eb3f6462.jpg?v=1745328919","url":"https:\/\/ilovecrystalsandgems.com\/fr\/products\/green-diopside-with-mica-and-calcite-specimen-244g-5-inch-afghanistan","provider":"ilovecrystalsandgems","version":"1.0","type":"link"}
