Opals Informative Guide
Opals are one of the most popular gemstones in the world, and for good reason. They are beautiful, unique, and come in a wide range of colors. But what exactly is an opal? Opals have long been treasured for their unique beauty, and today they remain one of the most popular gemstones. Opals come in a wide range of colors, from the deep hues of black opals to the delicate pastels of Ethiopian opals. No two opals are alike, and each stone exhibits a different play of color. When choosing an opal, it is important to select one that displays your favorite colors. Opals are typically found in Australia, and the Lightning Ridge region is famous for its black opals. These stones are considered the rarest and most valuable type of opal. Whether you choose a black opal, an Ethiopian opal, or any other type of opal, be sure to select a stone that is perfect for you.
An opal is a type of mineral that is made up of hydrated silicon dioxide. The word "opal" comes from the Latin word "opalus," which means "precious stone." Opals are found all over the world, but the majority come from Australia. In fact, Australia produces 97% of the world's supply of opals!
Opals typically have a milky or glass-like appearance and are translucent. However, some opals can be quite opaque. The color of an opal is determined by the type of impurities that are present in the silicon dioxide. For example, opals that contain traces of iron oxide tend to be red or orange, while those with manganese oxide can be pink, purple, or blue.
One of the most unique things about opals is their "play-of-color." This refers to the way that the stone seems to change color when viewed from different angles. The colors in an opal are actually caused by light diffraction, which occurs when light waves bounce off of tiny silica spheres that are embedded in the stone.
Opals come in a wide range of sizes and shapes. They can be cut into cabochons (a smooth, rounded gemstone), or fashioned into beads or other jewelry.
Opals are relatively soft stones, so they require special care when cleaning and storing. It's important to avoid using harsh chemicals or cleaners on opals, as this can damage the stone. Opals should also be stored away from other hard gemstones, as they can easily scratch each other.
If you're interested in adding an opal to your jewelry collection, be sure to consult with a qualified jeweler to find the perfect piece for you.
