A brief information about Opals and south sea pearls

Opals are very popular in Australia and for all right reasons. These opals look excellent and offer superior and appealing look to the person when you have them. If you don't know about opals, let me explain in brief. Opals are amorphous, non-crystalline silica, (silicon dioxide, alike to quartz and sand) a hydrated form of silica (SiO2H2O) in a rigid gel form containing between 1% and 21% water.

Opals have the unique ability to diffract white light into excellent colors of the rainbow and that too without any impurities. When the light is split by the voids between the spheres, the color is created.

The south sea pearls are also something that you should definitely long for. They are the best pearls across the world and you can find them on the jewellery shops or online jewellery stores.

All you need to do is to find the authentic jewellery store and ask for opals and south sea pearls and that is all.
