When we talk about “rocks” as Jewel Snobs, we often mean huge gems like the ones on colossal diamond engagement rings. In the case of this ring, it’s a literal rock. Who knew that such a stunning, high-end piece of jewelry could be built off of a mere pebble? Athenian designer Dolly Boucoyannis! She studied jewelry design in the UK, gemology in the US, and goldsmithing in Florence, so she comes at design with a truly unique, original perspective. She masterfully cut two holes into this pebble to fit in a gold band that loops into a large, flowery support at the base of the ring and covers the top of the rock with a row of shining white diamonds. The juxtaposition is immediately striking. You’ll never look at the pebbles in a riverbed the same way again. Available on Luisa via Roma for $1,375.
