CHURCHILL Private Label 18K Yellow Gold Sapphire Earrings. The rarest color of sapphires, known as padparadsha, are a fleeting tone of pink that just goes to orange. Some experts call them "shrimp" colored sapphires. Here, this tone of sapphire is combined with pink to hot pink sapphires in a stunning match up. Some appear as deep apricot; others are a softer peach shade. Stones are all oval in shape, but they are mounted randomly south to west and north to south. We hope you enjoy them as much as we enjoyed producing them.
