What appeals to me about this set of stacking rings is their rugged finish — they remind me of fusion-crusty meteorites and worn, pitted (by cosmic rays and space dust?) metal. The rose gold adds a striking note of purity amongst all that patina.
A pair of delicate stacking rings in sterling silver and red (rose) gold.
One little moonrock with an orbiting 9 carat gold satellite, both on delicate bands. The silver is oxidised, then the surface of the moonrock is polished back to bright, leaving the craters contrasting. The bands are left black and buffed to shininess, like coal.
