What Makes Australian Opals What It Is?

The Australian Opals are the gemstones which are multi-coloured and contain small spheres of silica organized in a regular pattern with water between the spheres. The sphere disperses white light breaking it into various colors of the spectrum. They are mostly included in the jewelery paired up with different kinds of other stones such as rubies, diamonds, and emeralds. 

The sphere of opal in Australia comes in all kind of colors which makes it a unique stone as it shows the rainbow-like colors. The process of diffraction of white light in various spectrums is known as “opalescence”.  When there is a larger sphere, it provides all kind of colors but the smaller sphere is mostly having blues and greens. Stones which are red in color are a rare phenomenon as it only occurs when larger silica is deposited. 

The different color of this stone shows a different kind of properties. The white stones are delicate and come across as pale in lighter background. The Black stones which are rare and valuable have a dark background and its color ranges from rich reds to greens, purples, and blues. The Boulder ones are cut with a natural host rock and ironstone on a back.

The black opals are the costliest and rarest of all the opals. It is mainly because of its dark shade because of carbon and traces of iron oxide. The dark shade helps in highlighting the rainbow colours, which cannot be seen on a white or light coloured opals. 

More the vibrancy of colours, the costlier the stone. For making the stone worthy to use in jewellery making, the back of the stone is attached with a black surface that helps in increasing the darkness of the stone and strength as well. 

Few stones have a natural layer of potch left on the back of the stone, which provides extra darkness and vibrancy of hues as well. The darker the stone, the higher the price it can fetch.  

Generally the stones are cut into oval shapes, but the natural shape of the stone will play a major role in deciding the final shape. Freeform or teardrop are the other forms of the stone that fetch a higher price in the market. 

A genuine dealer can give the best opal at the correct price. So before purchasing opal, verify the prices from two to three dealers.
