Old Inlaid Shell Necklace

I’m wondering about the approximate age and value of this piece. Assume it’s Santo Domingo. Shell is inlaid with turquoise, coral, jet, and a brownish stone I can’t identify. Could it be petrified wood? Any info/ideas would be appreciated.

Hello, thanks for sharing. I don’t believe the piece to be that old, maybe 1980s. The brownish stone is olive shell.

Thanks so much for the clarification, Jason.
