Diopside is a calcium magnesium silicate and includes several different gemstone varieties, each with a hardness of 5-6 on the Mohs scale. Diopside is best known for the vivid green chrome diopside, but the black diopside exhibiting asterism or the star effect is also important. Chrome diopside is colored by chromium and displays a forest green color similar to tsavorite garnet and chrome tourmaline. Tashmarine diopside is a brilliant yellow-green diopside from Tajikistan, Uzbekistan and Western China. This is a non-chromium-bearing diopside with a lighter and brighter color than the deep forest-green color typical of chrome diopside.

Happy about the experience of the store, a lot of stone urge very nice
when I need a colored stone I check gem select. a trusted supplier for at least 10 years for me. many of the online sites have gone black but gemselect continues to satisfy me. oh sure there are many windowed and poorly cut stones here so paying some attention is critical. remember these are not custom cut stones but rather cut by old methods and the aim is to keep weight up at the expense of optical perfection. remember that colored stones are about color as the first consideration. I just wish gemselect offered rough for those who want to cut it.
