Grandidierite
Grandidierite is a very rare collector's gemstone named in honor of the French naturalist and explorer of Madagascar, Alfred Grandidier. Grandidierite is often referred to in the top 10 rarest gemstones in the world and occurs in aluminous boron-rich rocks and in pegmatites. It was first discovered in Madagascar in 1902 and then in small quantities in other areas of the world, but most grandidierite specimens come from Madagascar. The greenish-blue color of grandidierite is caused by the presence of iron. Grandidierite gemstones are usually faceted and sought after by collectors.

They had an extensive gemstone selection in all different cuts, sizes, and colors. They also had very good and workable prices. All of these aspects pulled me in as a customer.

I wasn't sure where to go to find a variety of gemstones to choose from in the size and shape that I was looking for. I'm really glad I found this website because the search options and filters made it really easy to find what I was looking for. The prices seem quite reasonable. This will be the first place I go the next time I'm looking for a gemstone!

I am impressed with the variety of the inventory and the information provided on each item. I like the pricing. The only reason I wouldn't recommend the site is I do not want to reveal my source.
