サーペンティン Serpentine is the name used for several different aggregate structures which are usually green, yellowish green, or brownish green in color. The finer serpentine is cut as cabochons for gemstones, or carved into decorative objects. Though serpentine is sometimes confused with jade, serpentine is usually spotted or veined.
The serpentine group includes as many as 20 different members, including verdite, which is often referred to 'African jade'. All the serpentines are a basic magnesium silicate, with many containing iron as well. Other elements may also be present in small quantities, including chromium, nickel and cobalt. Serpentine varieties are found in many places in the world, including Afghanistan, Burma, China, New Zealand, the USA, Canada, UK, Greece, Italy and Norway.

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.
