Raw chunk of Ethiopian Opal set in an adjustable plated claw ring. This one has a dark red base with a green/teal center. Beautiful flashes of pink, green, orange & blue. These are jewelry grade opals & cannot go in/around water because opals are porous and absorb any liquids. Always keep your Opal in a dry environment .To clean your Opal jewelry just use the micro fiber cloth I provide in every jewelry order. Opals are sourced from Opal trove.
