What color is it?: Generally a pastel yellow as shown above, ranging to pink and colorless.
What is the story behind this gemstone?: This is a very unique gemstone that offers some beautiful pastel colors. It is rather difficult to find so if you see one in a store or at a gem show don’t hesitate to buy it. You may not see it again for quite a while. And be prepared to see mainly small stones. It rarely occurs in large crystals. The specimen above weighs 2.26 carats and is considered a rather large petalite.
Can I wear it everyday?: Yes, for a necklace. But it is rather brittle so don’t try to wear it in a ring. It will be very hard to replace if you break it.
Is it expensive?: It can be. About the same as a nice quality pink tourmaline.
Is it a birthstone?: No.
What do I need to know before going shopping?: Call ahead. Few jewelers will normally carry this rare gemstone in their inventories. Best bet may be to visit your local gem show. This may be a stone that only a lapidary or gem dealer will carry. But if at all possible…ask your local independent retail jeweler to find a petalite for you. This will be the only way you will know that you are getting the real thing.
