Opal is such a beautiful and attractive gemstone that all kinds of jewellery like rings, earrings, necklaces, bracelets etc. look very impressive. However, the demand for opal in making special jewellery is not less nowadays.Black opal pendant is an attractive gemstone that flashes with all the colours of the rainbow. These are made from tiny spheres of hydrated silica; Silica is the component of sand that makes sand! As these are formed, tiny droplets of water get stuck in the latticework of the sphere in an irregular pattern. The water radiates light into the gemstones, resulting in a magical play of colours, known as opulence, for which the gemstone is famous!
However, not all opal earrings are the same! There are four broad categories of opal, white, black, boulder and crystal, differing in their clarity and the colour of the host rock. They also display different levels of opacity. And although fashion indicates the variable popularity of individual opal types, certain types of opals lend themselves better than other types of opal jewellery. So which form suit is best for jewellery?White opal is the most common of these gemstones. They have a milky white appearance that can range from opaque to transparent. The more milk like the background of the host rock, the harder it is to see a glimmer of burning ambiguity inside. Their beauty is most easily seen in strong direct light. Their pale appearance and relative affordability mean that they are often set in silver metal for everyday jewellery, such as cabochon.Black opal ring is the rarest, most tempting and most expensive form of gemstone. Some of the best in the world comes from the Lightning Ridge in Australia. The dark host rock is usually black, blue, brown or grey and provides a perfect background for viewing the glorious colours of this gemstone. They have the appearance of an angry storm cloud behind a rainbow.Black Opal's play is best appreciated in full view. These are usually set as cabochon. And they're dramatic enough to hold themselves in a diamond as well as a fine piece of australian opal, such as a wonderful anniversary pendant or an engagement ring.Boulder opals are always cut with some host rock still attached. These are usually set in jewellery as thin pieces or shapes of baroque stones. These are unusual and extremely interesting pieces that will attract comments and admirable attention! These are not easily set in rings but make great pendant necklaces.Types of crystal opals, such as fire opals are transparent and usually have a good transparency which is seen in a strong diffused colour. These are the only classes of gemstones that are usually oriented before being set in jewellery. Fire opals have a slight opacity but are valued for their colour instead. They make nice rings, earrings and pendants.
