There are several misconceptions about the gemstone opal one of them is that it brings bad luck. But believe us buying an opal engagement ring for your better half will only bring a smile of joy on her face. A very common superstition about opal gemstone is that it brings bad luck to purchase an opal for oneself, but good luck if it is a gift from someone.
These beliefs about this beautiful gem have been prevalent throughout the history. But some experts believe that such myths were perpetuated by diamond dealers in 18th and 19th century because they feared that this gemstone ill steal away diamond customers. Though after huge amounts of opals were found in Australia efforts are going on to change the perception of the customers regarding this gem.
We would recommend opal engagement rings for their rainbow hues, making opals some of the prettiest stones around. The real exciting feature of this stone is its ‘play of color’ or that beautiful display of rainbow shades on this gem.
For all those who are interested to know what makes this gem unique here is the science behind this gem. Opals are in fact amorphous “lumps” or “balls” of mineral silica or in other words it is a non crystalline form of silica.
So, if we want to know how it gets formed it is water carrying dissolved silica seeps through sand and dirt, and then eventually the silica particles are deposited in cracks. When the water evaporates, the silica particles cement together to form the opal.
As for this ‘play of color’ the identifying feature of this gem it is caused by the diffraction of light. Now each opal stone has small spheres of silica, most them are of similar arrangement and size. When the light gets reflected from these spheres it gets divided into spectral colors, and the stone appears to contain all the colors of the rainbow. But if these spheres are very large and not of uniform size and arrangement of the colors become more limited.
Though we are all impressed by the beautiful and colorful display of these opals it has its share of shortcoming. One major flaw is that unlike diamonds, opals are a much softer stone. If we compare the two stones on Moh’s scale of hardness, in comparison to diamond which is considered to be a 10 on this scale, the opal rates between a 5 and a 6.
This shows a jewelry with opal has to be handled with care as it can break more easily and you must be careful to treat it with care and look for a ring setting that best preserves its integrity. We would suggest semi-bezel setting can be a good choice.
Now if you have made your mind that you want an opal ring for your wedding you will be overwhelmed by the impressive color range.
