Yowah Opal and Aquamarine Ring
This Opal and Aquamarine Ring is made from sterling silver with a 24ct gold setting. Size P1/2 

This Opal comes from the Yowah Opal Fields and was shaped  by me. Highlighted by a 3.5mm Aquamarine set in a 24ct gold setting. The ring shank is made from 2mm round sterling silver. The top measures 19x15.5mm. The ring sits very comfortable on the finger when worn.  

The Yowah Opal field is located in Outback Queensland -Cunnamulla Country. The occurrence of precious opal in siliceous ironstone nodules is generally referred to as Yowah Nuts. These nuts range from about 5mm to 200mm across, have a spherical or ellipsoidal shape, and show alternate concentric rings or bands of light- and dark-brown siliceous ironstone.

About 100 million years ago, the vast sea that covered 60 per cent of Australia – from Coober Pedy in South Australia to the Gulf of Carpentaria in Northern Australia began retreating. Water ran through the earths' deep cracks and picked up silica from sandstone. This silica-rich solution was carried into voids, caused by natural faults or decomposing fossils. As the water evaporated, it left behind a silica deposit. This cycle repeated over very long periods of time, and eventually opal was formed.  It is separated into two groups, the common opal (also known as potch) and the iridescent, richly coloured opal.
