The three necklaces shown, by Hayley Starr, are meant to be worn together and are priced so that you can afford all three.
Sold at LAs Roseark, their site notes, “Star comes on 15″ chain; moon comes on 16″ chain; heart comes on 17.25″ chain.”
Each sells for USD $85. The opals are described as “earth friendly” – not quite sure what that is supposed to mean, whether they are synthetic or natural, or doublets or triplets. And the chains are gold filled.
