Last month we were asked to create a bespoke ring with a diamond design to set and oval shaped Australian opal stone a customer had. The customer wanted the opal tp be set with diamonds and mounted on a mixture of 18 carat white gld and 18 carats yellow gold. Our jewellery designer put together the following designs with diamonds set on the shoulders with the mount of the ring in 18 carats white gold and the band in 18 carat yellow gold. Once the customer picked the bespoke ring design, we printed the head, where the opal and the diamonds will sit and the band of the ring separately into a three dimensional wax models. Using the lost wax process the wax model of the ring was skilfully cast into a mixture of 18 carat white and yellow gold ready for the ring to be assembled and the stones to be set. The final design features the oval Australian opal held in a 4 claw 18 carat white gold bezel setting with 14 round brilliant diamonds set either side in 18 carat white gold rub over settings. The diamonds total 0.21 points in carat weight. The centre stone is a light Australian opal with different swirls and flashes of vivid colours seen on the white background. The opal combines glowing, luminous colours of some of the most beautiful gemstones that sparkle together. Including the deep blue of a sapphire and the shining purple of an amerthist.
About Australian Opals
The vibrant colours in Australian opals are the result of a combination of Silica and water. Australian opals were formed millions of years ago when parts of Australia were covered by the sea and stone sediment were deposited along the shoreline. When the water flooded back over the shoreline, it contained silica, which flushed into the stone sediments. This resulted in cavities and niches in the stone, as well as remains of plants and animals.
