Please note, I did test the quartz with a gem tester.

Estate Find Artisan Pendant.. I am not sure what the slab that the rose quartz is attached to. The pendant is approx 2.5" x 1.5" give or take a tiny bit since it appears to be handmade. There are no markings of identification on this piece... it's very unique. See photos for assessment. Has a very boho vibe to it.
