A lovely cluster ring containing an oval opal with excellent play of colour (not shown well on our images, possibly more accurate on the black background). The opal is 10x7mm (just under 3 carats). Claw set and surrounded by fourteen brilliant cut white diamonds 0.10 carats each (1.4 carats total), colour G-h, clarity Si all set into platinum.
Head 16x13mm, depth 9mm, weight 7.7grams. Shoulders are a fleur de lys pattern. 18 carat gold shank, this hallmarked London 1972. Condition- fine to excellent.
Basically, opal is made up of water and silica (the main component in glass). A silica solution forms when silica from under the earth mixes with water. This solution fills voids or is trapped in layers under the earth, and opal begins to form.
Over a long period of time, the solution settles and the water evaporates, allowing the gradual formation of layer upon layer of microscopic silica spheres. The spheres are formed because particles of silica spontaneously adhere to other particles which form around it. Its said that opals are more fragile than most gemstones, however they’re not as fragile as some people imagine. Opals are about the same hardness as glass, so imagine you’re wearing a piece of glass and you’ll get the idea. Avoid heavy manual labour, moving furniture, sport, gardening or any other vigorous activity where your opal might impact with hard surfaces and your opal will enjoy a long and happy life. With a little care it’s easy to take care of opals.
