Ethiopian Opal

Posted by Picasa
This is my last picture from the gem and Mineral Show at Cartersville. I really enjoyed the show as well as the Tellus Museum and highly recommend it as a field trip. This picture is of Ethiopian opals and the bits of color you see are the opals. The matrix is a soft material that can easily be scratched off with a fingernail. Some of these are the "new"  (recently discovered) chocolate opals and are brown (not surprisingly). However, I think the blue, green, and red ones are the most beautiful.
