About Color-Change Diaspore

Diaspore, sometimes marketed under the name Zultanite, is a color change gem from Turkey recently introduced to the international market. Diaspore is a hydrated aluminum oxide colored by manganese. It was first faceted as a gemstone in the 1980's, but has never been mined commercially until recently. With reasonably good hardness (6.5 to 7 on the Mohs scale) and good brilliance, diaspore has been attracting considerable attention in the gem world.

Under natural or fluorescent light, diapsore has a kiwi green color, with flashes of yellow. Diaspore displays a champagne color under incandescent lighting, and when exposed to subdued lighting, such as candlelight, it has a pinkish color. The larger the stone, the more pronounced the color change effect will be.

I love this website. I have been browsing for years and now can utilise the stones in jewellery. Sooo many stones and so little spare time to make them into beautiful things

I was pleased with the amount of information they offered along with the accuracy of such information. Navigating their website was effortless as well. Although, I wish they had a wider variety in a particular gemstone, I was satisfied overall.

Easiest website to find what I’m looking for as a starter gem collector. Many years in precious metals I decided to expand my interest. This website makes it easy to search exactly what I’m looking for with great description of what I’m purchasing.
