The listing, 4 Carats of Rough Ethiopian Welo Opal - Natural Gemstone has ended.
This is an opal in the rough, as natural as it gets. : ) It was mined in Ethiopia. I tried to take pictures at different angles to show the colors, but the pictures don't do this justice!! The pictures are a little blurry, but they show the flashes of color better. Go figure. LOL I am thinning out my collection, but this will is the last one I will part with.
