Polished Clear Quartz Gem Rock Necklace 17.75”

I don’t The anything about this. Purchased at an antique store. Real polished clear Quartz stones. The “S” Shaped clasp is what I believe to be sterling silver. The jump rings are not. Please note the knots or string this is strung on is soiled. Personally I think it would be cool to dye the string and have a color showing thru the stones. The stones have very few inclusions. Approx 17.75” Long. You might be able to wear as a bracelet if you change the clasp.
