Andalusite is a little known gemstone which usually comes in earthy or fall colors such as orange, yellow, brown, green and gold. It is rated at 7.5 on Mohs hardness scale so it is suitable for all types of jewelry. It is not often found in very large sizes but is available in convenient calibrated lots for jewelry design or display.
Its special feature is the change of color seen when the gemstone is moved from angle to angle. With Andalusite, you do not need to move the gemstone very much to see the effect, very often green, red and orange flashes can be seen with only the slightest of movement.
It is usually facet cut to emphasize this color shift. The most common shapes are round, which gives an almost mosaic result as the various colors blend into each other, or longer shapes where the lighter colors in the middle are capped by dark colors at each end.
I would recommend gem select. They care about all details from description to quality to packaging to shipping. I specialize in turquoise so I would like more explicit provenance than "American"... Couldn't they give me mine or at least state? Never the less very classy. Also, their turquoise cabochons are very thick for good and bad. I cut many in half to make them more versatile and commercially useful. If one can't do that then you are going to have to settle for wire wrapped jewelry. I think that overall thy are a great resource.
I am looking forward to my purchased opal to be set in a ring and a necklace for my sister for her birthday present I am interested I working with this company in the future if we are happy with our opals thanks so much for your communication
