Cat's Eye Diaspore: Buy Cat's Eye Diaspore Gemstones

Cat's eye 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 1980s, 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.

Cat's eye diaspore gems are fairly rare. The chatoyancy or cat's eye effect is caused by the alignment of rutile needles.

My only complaint is that there are so many beautiful and affordable stones that I get distracted from what I planned to order.

I am of the opinion that the company gem select cares about the product beautiful gems it sells and the cost of the gem I purchased was small i was treated as if it cost a lot of money and product was described in detail and i felt good about the little stones i had ordered.

I placed order#384714 based on the picture on your website and the stone came in much darker. I'm sure it's the same stone i ordered but your lighting made it seem a lighter blue. I was trying to match a stone for a customer and based on the picture it would have been close enough but the stone in person is a mile off.

I really enjoy browsing through GemSelect. The selection is always marvelous and I love how detailed everything is described. The only thing I noticed is that when browsing through my phone, the videos of the gems do not load. If there were more videos of the gems, that would be amazing, though I understand that is a lot of work on GemSelect's part! Checking out is also very fast and easy, and I love that the return policy is very good, though I hope I don't have to use it anytime soon.

I love the clear description of the certification options. It's very rare to see a gem site that offers a deep explanation of each institution that would certify the stone(s).
