jewelry factory china Baolong decomposition: Opal series gems

Postat pe de Kingjy

The word Opal is derived from the Indian word “precious stone”. În ultimii ani, the Hong Kong jewelry industry has translated Opal as “Aobao”. It has the emerald greenness, the vividness of rubies, the brilliance of amethyst, the clarity of crystal… its colors and patterns are so integrated and beautiful. This effect is called the “opal effect”.

Among all kinds of opals, opals with a black background are particularly dazzling in color and the price is the most expensive.

Orientals regard opal as a sacred gem of loyalty and believe that wearing it can protect you from disease. Europeans think that opal represents inauspiciousness. Cu toate acestea, Queen Victoria of the United Kingdom once gave her 5 daughters an unusually beautiful opal as a gift.

Opal contains 3%-30% crystal water. As the time of exposure to the air increases, it will gradually lose these crystal water, causing cracks or blemishes to weaken the light of the protein. The way to remedy and restore it is to put it in oil, spermaceti, or bury it in wet sawdust, in short, try to minimize the time it is exposed to hot conditions.

In the Smithsonian Society of the United States, there is an opal weighing 2,610 carate. Australia once produced a Pandora opal weighing 711 carate.

Opals on the market are natural ones, and some are artificially optimized or combined or artificially synthesized.

At the end of the 19th century, the eastern part of the Czech Republic was rich in high-quality precious opals. Later, new mineral deposits were continuously discovered in Queensland of Australia, Coober Pedy and Lightning Ridge in South Australia, which made precious opals become Australia’s national treasure.
