Boulder Opal Beads

Boulder opal is hard to find, trust us! We love this stone because it combines the natural earthy gemstone look with the unmatched beauty of the glowing blue color-play of opal.

Our Boulder Opal gemstone beads are comprised of beautiful brown ironstone, with its delicate layers of chocolate and golden brown, marbled with absolutely gorgeous veins of precious opal. This is an extremely rare and special stone – snap it up while you can!

Precious opal consists of tiny, transparent spheres of hardened silica gel with water in the intervening spaces. Unless the silica spheres are precisely arranged and of the correct size, the color-play that is characteristic of precious opal cannot form -- making this material extremely rare. Boulder Opal is found in Queensland, Australia where thin veins of colorful precious opal forms in cracks and fissures within brown ironstone boulders.
