Chrome Diopside

saf-ahyuh r

Chrome diopside has several origins, but most of the finest material, and the only commercially viable deposit, is in the Republic of Sakha in Siberia, Russia. As you can imagine, production of this Siberian treasure is sporadic due to extreme winters that last more than eight months. The vivid greens of chrome diopside are a welcome alternative to rare and pricey emerald or tsavorite garnet, but has yet to gain mainstream recognition due to its limited availability. Minor sources of chrome diopside include Australia, Austria, Canada, Finland, Italy, Madagascar, South Africa and the United States.

History

You will fall in love with the eye-catching green of chrome diopside. This stone is pleochroic and changes color when viewed from different angles. Its color is natural, which gives it a strong appeal to those who seek untreated stones. It's also refractive, which means that when well cut, chrome diopside is quite brilliant. And it's occasionally seen with cat's-eye chatoyancy. This beautiful stone was discovered in Siberia. The part of Siberia that produces this gem is so teeth-chattering cold that miners can dig down to it only when the temperature warms up enough to thaw the frozen earth that locks it in.

More About Chrome Diopside

Although chrome diopside wasn't a common gemstone before the 1980s, it wasn't unheard of. Some people believed that it fell from the Tree of Life. Others believed this stone led to the practice of burying loved ones with a chrome diopside, to make certain that they had an opportunity to move on to a new cycle of life. Still other folklore suggests that the stone brings tranquility and peace. For that reason, some cultures recommend that a chrome diopside be affixed to the forehead at night - in the belief that it would bring sweet dreams. Some say that the green of this stone connects one directly to the earth and helps make a direct connection to earth's energy.
