Opals! They have to be one of my favorite stones. From black with neon streaks to white with incandescent hues, opals come in many varieties and not a single one looks the same. Whether making your own, or looking for a signature piece, opals are one of those stones that go with everything. They can be found in many places around the world, but Australia is where most of them come from. The darker the stone, the more expensive and rare, and their price can go up to over $2,000 per carat! During the 2013 Oscars, Jennifer Hudson wore a stunning pair of Sutra earrings, that InStyle Magazine later named one of the Best Jewelry Moments of this past award season.
