Hambergite
Hambergite is one of the lesser-known gemstones. It is usually almost colorless, with the vitreous luster of glass when cut. It is quite a hard material, with a hardness of 7.5 on the Mohs scale, so it takes a very good polish. Hambergite derives its name from the Swedish geologist and geographer Axel Hamberg (1863-1933).

There are several features that make hambergite quite unique. It has very strong double refraction, with a birefringence rating much higher even than zircon. Hambergite also has a low density, but a high refractive index, a combination that is very unusual in the gemstone world.

I love GemSelect! Every stone that I ever purchased has been carefully packaged, and sometimes comes with origin info. The stone I just ordered is for my engagement ring, because my Fiance is making my ring! I am so amazed with the selection that this site has, and I am so impressed with the prices.

Site layout was great. Item description was good but this is first purchase so I will have to wait and see how satisfied I am with product. But this step of process was great!

Well I was looking for the perfect stone to set in a ring for my partner. I found this Garnet on a website called Gemselect and it captured my eye. I had to have it for her. It looked as perfect as she does. I got the stone I wanted for $150 shipped straight to me. It’ll be the perfect Christmas present
