@Oceana – Some types of barite make very interesting jewelry. My sister lives in Oklahoma, where the barite rose is the state rock.
These rocks look like roses because of their shape and color. What's cool is that this occurs naturally. Man did not have to carve them into the shape of the flower, and color did not need to be added.
The red dirt in Oklahoma gives the barite roses their color. My sister has a necklace made from a barite rose wrapped in wire for support, and it is one of the coolest pieces of jewelry I have ever seen.
I have also heard of clear barite crystals being used as jewelry. These come in long rectangles. Since barite is soft, it can be carved as needed.
