グランディデライト 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.

My experiences with Gemselect have always been quite satisfactory. The items are accurately photographed, a detailed description and provenance provided and the compare feature helps customers select the best gem for their needs. I have often recommended this source and will continue to do so.
I ordered several specific items from Gemselect. Items are always packaged very carefully to protect the content. Gemselect always encloses a card of authenticity which documents the entire stone, its size, clarity, etc. All of the items are as they were described. I would highly recommend them to anyone who’s in the market for a gem.
I frequently check the GemSelect website for a variety of gems. I've been very satisfied with the selection and quality of the top rated gems. All of the purchases I've made have turned out beautiful pieces of jewelry.
