This is a spectacular hydrophane opal from Welo, Ethiopia. The blue color is truly intense in this stunning opal, and it would make an amazing centerpiece on a piece of jewelry or it would accent almost any colored stone collection!

This stone weighs 3.11 carats and the dimensions are 10.61 x 5.87mm deep. Finding a Welo opal over three carats with such intense pure-blue play of color is very difficult. To find one that is also free of matrix or inclusions is even harder- but this is just such a stone.
Some people say this makes them think of a globe- and that is quite easy to see. This stone is guaranteed to thrill you or you can have a full refund. My wife and I always select these gemstones from very large parcels, and we only pick the most beautiful stones. Our stones are definitely not commercial quality gems like you see in mass-market jewelry. We always think of beauty first, and price-point second.
