Discovering the Enchanting Beauty of October Birthstone - Opal

Some stones are pretty. Opal is different. It holds an entire spectrum of color inside one stone and it changes every time the light does. The October birthstone has earned its reputation. Opal is one of the few gems that genuinely shifts in your hand flashing greens, blues, corals, and golds depending on the angle, the light source, the time of day. It's not a trick of the setting. It's the stone itself. If you're shopping for an October birthday or finally treating yourself to something personal, opal jewelry is worth a close look. Here are eight pieces that show the stone at its best.
