Such a beautiful piece, I only wore a few times. Bought from a very high end boutique in NYC Most likely gold. I’m almost positive although unmarked, I put it in gold cleaner and it came out wonderfully, it shows many signs of being solid gold I’m unsure if the stone unfortunately as I bought this awhile ago. It’s mostly clear, and has some orange reflective streaks/ little wiery minerals inside. Such a gorgeous piece! Size 7 US Open to most offers as I really don’t ever wear this. Ask my any questions, I’m more than happy to answer 💕🌷
