The Story of Andalusite Gemstones

Consumer Information

What color is it?: As shown by the photograph above, andalusite is a combination of two to three colors, depending on how you look at it. The two basic colors are green and brown as shown above. But later down this page I will show you something very unusual about this stone.

What is the story behind this gemstone?: This gemstone is a bit like tanzanite in that it shows two very distinct colors at the same time. The difference is that andalusite shows brown and green, rather than blue and purple of tanzanite. But the ability for any gemstone to split a single beam of light into these two very different colors that your eye can actually see is very, very rare in the gemstone world.

Can I wear it everyday?: Yes, andalusite is a very durable gemstone for wear.

Is it expensive?: It can be. A fine quality andalusite can be a bit difficult to find and a bit pricey when you do. But it is well worth the effort and the price. Nothing else like it in the gemstone world. And you will certainly have something no one else on the block owns.

Is it a birthstone?: No

What do I need to know before going shopping?: Just be sure to call ahead. This is not a gemstone that many jewelers will carry. But the stones are available so don’t hesitate to ask. But….look at the following photographs…
