Though moonstone is not as hard as most other types of jewelry gemstones, it remains one of the most popular gemstones for jewelry. In fact, moonstone jewelry has been worn for centuries, dating back to ancient Greek and Roman civilizations.
Moonstone jewelry should be limited to protective-style jewelry applications, such as earrings, pendants, pins and brooches. Moonstone can also be worn as rings, but care should be taken to prevent scratches and blows. The wearing of moonstone rings should be limited only to occasional wear as moonstone gems are not durable enough to handle everyday wear and tear like quartz or other harder gems. Moonstone is most often faceted, but some transparent materials may be faceted and these faceted stones are excellent for open settings, such as prongs. When cut en cabochon, designs are limited to closed style settings which can accommodate flat backs.
