What color is it?: I guess you could best describe it a the color of fire. Looking at a fire agate is much like looking down into the burning embers of a fire. Which is exactly how it got its name. If this sounds a little schmaltzy then you have never seen a really nice quality fire agate. Because once you have the above description will be the only one you will have too.
What is the story behind this gemstone?: This is a very unusual form of chalcedony or the quartz family, known as agates. This particular type is unlike anything else in the gemstone world because looking into a nice fire agate makes you feel like you are looking deep into a burning ember. (That's just the only way I know how to describe it)
Can I wear it everyday?: Yes it is very long wearing and tough.
Is it expensive?: Relatively inexpensive. About the same price as a nice piece of Lapis Lazuli in the finest quality.
Is it a birthstone?: No
What do I need to know before going shopping?: First, don't shop for fire agate on eBay. Or you might wind up with some mid-quality stones like I did with the one's on this page. Fire agate must be seen in person to be truly appreciated. Second, if you are buying it rough, spread a little spit on the stone to get a good idea of what it will look like polished (which is why these stone look a little wet, but just wait until we start testing cultured pearls). Beyond the above look in your independent jewelry stores who carry a lot of colored stones and will have a selection to offer. Every single fire agate on the planet will be a little bit different. So you will want to be able to choose from several to make sure you have one you really like.
