The Atlantis Tale collection features studs and rings that that emulate the organic shapes of stones and rocks, with abalone shells and other mediums encased in layers of resin. Layering of resin creates depth, giving it more dimension. 
This pair named Blue Opal, is encased with blue and green abalone shells and gold foil in layers on resin. The opal effect is mesmerizing. This is another variant of the Blue Opal.
Ear posts are 925 silver with 14k gold plating.
