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 ordered my gems off this website called GemSelect, they have a good selection and it's easy to navigate. You can also have the gems professionally certified when you buy them, but they do provide certificates of their own.
Good experience with finding a variety of stones. Due to the vast selection, it is important to be able to search, and I had issues with the site not returning matches when I put in a specific size range. I was eventually able to narrow it down by sorting the items by size, but it was slower than if I could have typed it in. I also wish Gem Select would offer lab created stones (fully disclosed, of course!) so I could get some exotic colors more frequently. Overall, I love browsing and will continue to patronize, but this would put the site as my #1 go to.
I have been browsing stones on GemSelect for a few months. They have such a large selection and I found some stones I had never even hear of before visiting GemSelect! I cannot wait to receive my order and show my gems off!
