7.09 carats of prasiolite - the green variety of quartz, also called green amethyst, with a cool, slightly muted sage-to-mint green that occupies a specific and appealing color territory in fine colored stones - in octagon cuts at approximately half an inch creates earrings with both substantial stone presence and architectural geometric precision. Prasiolite's color is translucent and soft rather than saturated, creating an earring with understated green sophistication rather than vivid color impact. The warm 18K gold over sterling silver setting adds the warmth that brings out the best quality of prasiolite's cool green tone. Elegant, unusual, and accessible.
