Opal is one of the world's most popular gemstones and the birthstone for the month of October. A nice precious opal can flash every color of the spectrum with an intensity and quality of color that surpasses the fire of diamond. The best opals command prices per carat that rival expensive diamonds, rubies, sapphires, and emeralds. This beautifully crafted Butterfly contains 4 pieces of Opal Austman Crystal alon with sesveral small glass beads. The over dimesnisons for the Butterfly are 5cm x 4cm and it is suspended from a 16 Inch Stainless Steel Chain. This necklace would make a great statement piece on an evening out.
