In China, opal is called "lion negative", "cat eye", "cat eye". As far back as the early Tang Dynasty, it was said that Tang Xuanzong had two treasures called "Lion". In the Yuan and Ming dynasties, the court's love for colored gemstones reached an unprecedented peak in ancient Chinese history. The gold and silver jewels embedded in the opal are even more precious. From the eyes of the cats in the Du Shi Niang Treasure Box, to the inlaid opal stone of the Dingling Wanli Emperor, the three-diamond gold band ornaments, and then the ancient cats in the ancient books...

Cat eyes licking cat's eye? Don't make a dizzy!
Before I knew the opal, there was a very confusing concept. I thought it must be clear first. Cat eyes (effects) and opal can be two different things!
Cat's eye
The cat's eye is actually an optical effect, just like literal understanding, this effect is very similar to the cat's eyes.
It can make the curved gemstones show a bright band of light. As the gemstone moves, the intensity of the band will change. When the cat's eye effect is placed under two light sources, the eyeliner will follow the rotation of the gemstone. The phenomenon of opening and closing is really like the eyes of a flexible and bright cat.
It is formed because there are a large number of fine, parallel-array filament or tubular inclusions inside the gemstone, and the refractive index of the inclusion and the gemstone is quite different.
Opal
The cat's eye effect can appear on many gems, and only the gold emerald with cat's eye effect can be called opal!
You may not have heard of gold emeralds, but the famous opals and marbles are gold emeralds.

Gold emerald itself is of great value due to its rare and gemstone characteristics. What's more, it can perfectly perform the cat's eye effect. Its light band is particularly delicate, bright and clear, and it picks up the gemstones of other cat eye families. A few streets.

Birthplace of opal
The world can produce opal, but it is not too small. Sri Lanka, Russia's Ural region, Brazil, Myanmar, India, Australia, Zimbabwe and other places have output.
But what's important is that the highest quality, most prestigious opal is only available in the Tranabra and Gower regions of southwestern Sri Lanka! The mining area here has a history of more than 2,000 years of mining.
