Ruby - The Queen of Gems

Jewelry Design Considerations

Ruby is hard and tough, making it a superb jewelry stone. For reasonably clean stones, no special wear or care precautions are necessary. They also come in many different shapes and sizes. This makes Ruby perfect for all kinds of jewelry including rings, necklaces and earrings.

Another popular form of ruby jewelry is with the rarer "Star Rubies".
