March 2018 Newsletter: The World of Green Gemstones

The color green has rich associations in many cultures, and studies in the psychology of color indicate there may a physiological basis for our affinity for green.

Green is the color of nature and is associated with growth, renewal, harmony and health. Green is in the center of the color spectrum and is thought to be the most restful and relaxing color for the human eye to view. So it is not surprising that green is regarded as a color that helps alleviate anxiety and depression, and brings with it a sense of hope, harmony and peace.

It is interesting then that green presents the widest range of choices in colored gemstones, from blue-green to mint, chrome green, forest green, apple green, yellow-green and olive. Dozens of gem varieties can be found in green, and one variety alone -- tourmaline -- can be found in nearly every shade of green you can imagine.

Some of the rarest and most valuable gem varieties occur in green, from emerald to tsavorite and demantoid garnet, alexandrite and imperial jade. Green hues are mainly due to traces of chromium and vanadium or iron.

Peridot is one of the few gems that occurs only in green, because it derives its color not from trace elements, but rather from its essential chemical composition. Peridot is green because it contains iron, and the depth of green depends on the percentage of iron in its crystal structure. Peridot can vary in color from yellow-green to apple-green to olive green.

Other particularly interesting green gems include apple-green chrysoprase, fiery sphene, yellow-green chrysoprase and mali garnet, and mint green tourmaline. There are fine green gems to suite every taste and budget, and more choices than in any other color of the spectrum.

Ask the Gem Experts

Each month we answer questions from our customers. We welcome your questions and you can submit a question from our contact page.

I love the purple colour you featured in your newsletter. I already have an amethyst, are there other gems that show the rich purple colour? DK, Canada

A deep violet or purple is actually quite a rare color in gemstones, which is why amethyst was so highly prized. The color can sometimes be found in sapphire, spinel and fluorite. But very recently a rare garnet in a true purple was found in East Africa, with some exceptional specimens from Mozambique that are among the finest garnets we have seen anywhere. For lovers of purple gems, these are really special. See our collection of Fine Purple Garnets.

I am planning to visit Bangkok in May and would like to buy some high quality coloured gems. Do you have a shop where I can purchase gems? AT, UK

We don't have a retail shop here in Thailand, but we do show gems by appointment at our office in the Silom Rd. gems district in Bangkok. Please contact us to arrange an appointment. You can browse our collection on our website and let us know the gems you would like to view while you are here.
