Cassiterite is a tin oxide mineral, and is the primary ore for tin. In addition to its important industrial use, it has some interesting properties that make high quality crystals valuable as gemstones. Cassiterite is reasonably hard, with a rating on the Mohs scale of 6 to 7. It tends to be opaque though thin crystals can be translucent. Its chief virtue is its multiple crystal faces and outstanding luster. Many specimens are graded as having "adamantine" (diamond-like) or submetallic luster.
Cassiterite is one of the densest gem materials known. It also has a very high refractive index, higher than zircon, sphene and demantoid garnet.
I received the product in a very well packaged parcel with complete detail of what I ordered. I opened the envelope, then the bag and then the bubble wrap and then the item containing the stone. I was so delighted at the color, the cut , the clean clarity and the sparkle of my Ametrine, love at first sight. Cant wait to get it set into a ring with some Citrine and Amethyst. Thanks so much
I have very appreciated the perfect correspondence among items proposed in the catalog on line and how much I have indeed received.Besides - not negligible - the fast delivery of the items selected on line.
Shipping is faster than anything bought and shipped here in the states. Mine came in 3 days and could be tracked all the way. I did return a gem but had no problems with delivery or refund thank goodness. Customer service was excellent with all my requests. Wanted eyes on to see actual color of gems and Gem Select were extremely helpful. Have used them twice. Very happy both times. Will use again.
