I love the assorted colors in the Mookaite beads, pretty yet very natural. As I've been working with different semi precious gemstones I've been trying to learn a little about them too.
Here's a quote from crystal-cure.com: Mookaite is an Australian jasper that combines the lighter colors of yellow and red jasper. It encourages the desire for new experiences and helps to keep a balance between external activities and the internal response to these.
I'm not sure I believe semi precious gemstones have healing powers but it is interesting to explore all the possibilities via the internet.
