Raw diamond pendant necklace with pink opal sterling silver clasp gold Arhaus

I believe the stone on this is pink opal. It’s beautifully luminescent. Genuine, semi precious stone with oxidized sterling silver clasp. There’s another type of stone that I think might be labradorite or another kind of opal on the chain. The pendant is a raw diamond with a gold plated or gold filled trim. New with tag was $169 made in the USA.
