Cat’s eye (Cat’s eye), namely “cat’s eye”, “cat’s eye”, “cat’s essence”. Opal, also known as oriental cat’s eye, is a rare and precious variety in jewelry. Because the light phenomenon shown by the opal is the same as that of the cat’s eyes, it is flexible and bright, and can change with the intensity of the light, hence the name. This optical effect is called the “cat’s eye effect”.

Cat’s eye refers to chrysoberyl with cat’s eye effect. Among all gems, there are many varieties of gems with cat’s eye effect. But in the national standard, only the chrysoberyl with cat’s eye effect can really be called cat’s eye, and other gems with cat’s eye effect cannot be directly called cat’s eye. The gemological circle calls the chrysoberyl with the cat’s eye effect as the opal. Generally speaking, the opal refers to the gold-green cat’s eye gemstone, and other gems with cat’s eye effect must be added with the name of the gemstone before the word “cat’s eye”, such as aquamarine cat’s eye, tourmaline cat’s eye, etc.

This gemstone has parallel distribution of “tubular” inclusions in the crystal, so after processing into a cabochon gemstone, it can produce concentrated reflection of light, and a light band like a cat’s eye “pupil” appears. Under the illumination of the cat’s eye, the rotating cat’s eye gem will open and close, exactly like a cat’s eye, hence the name “cat’s eye”.

Alexandrite cat’s eye: When the golden-green cat’s eye, that is, the cat’s eye contains chromium, it sometimes shows a discoloration effect, which is very expensive and very rare.

Introduction to cats eye stone

Strictly speaking, “cat’s eye” is not the name of a gemstone, but an optical phenomenon that appears on some gemstones. That is, when a hemispherical gemstone is irradiated with strong light, a narrow and bright reflection will appear on the surface, called “cat’s eye flash” or “cat’s eye live light”, and then named according to what the gem is, if the gem is quartz, it is called “Quartz cat’s eye”, if it is chrysoberyl, it is called “golden green cat’s eye”. There are many kinds of gemstones that may have cat’s eye glitter. According to statistics, there may be as many as 30 kinds. In addition to quartz cat’s eye and gold-green cat’s eye, there are mainly “pyrite cat’s eye” and “aquamarine cat’s eye”. Because the golden-green cat’s eye is the most famous and precious, it is also called “cat’s eye” for short, and other cat’s eyes cannot be called this way.

Opals are often referred to as “noble gems”. Along with alexandrite, it belongs to one of the five most precious and high-grade gemstones in the world. Opals are mainly produced in gas-derived hydrothermal deposits and pegmatite dykes. The world’s most famous opal origins are Terranabra and Gower in southwestern Sri Lanka. Opals are also found in countries such as Brazil and Russia, but they are very rare.

The selection of opal is based on factors such as color, position of eyeliner, shape and weight of gemstones. For high-quality cat’s eye gemstones, the cat’s eye line should be thin and narrow with clear boundaries; the eyes should be opened and closed flexibly to show lively light; the color of the cat’s eye should be in sharp contrast with the background; and the cat’s eye line should be located in the center of the arc. When purchasing, you should distinguish the opal from other gemstones and artificial cats according to the identification characteristics, and buy genuine opals.

Like other gemstones, the bigger the opal, the harder it is, so weight is still one of the basic elements in evaluating an opal. But the most important thing that affects the opal is the color, the condition and the evenness of the eyeliner.

The best colors for opals are very strong yellowish greens, tans and honey yellows, followed by greens and then slightly darker browns. Very white yellows and very white greens are worth less. The worst are variegated and gray.

The best opal eyeliner should be narrow, well-defined, bright, and centered on the gemstone. Regarding the color of eyeliner, some people like silvery forehead color, while others prefer golden yellow, while green and blue-white lines are more neglected. The body color is opaque gray, often with blue or blue-gray eyeliner. However, whatever the color, it is important that the eyeliner contrasts with the background and appears clean. The eyes should be able to open wide, the bigger the better, and they should be sharp when closed.

Processing technology (especially the degree of symmetry) is also an important factor in evaluating opals. In order to make full use of the original stone, the purpose of leaving it thick is to increase the weight and sell more money. But the result backfired, the asymmetry seriously affected the beauty of the cat’s eye, and no one offered high prices. The correct way is to keep the appropriate thickness below the waistline of the gemstone and grind it into a small arc. To keep the angle low, this will help to make the gemstone set firmly on the support.

Some natural crystal crystals have natural cotton wool, ice cracks, mineral deficiencies, and artificial flaws in the grinding process, and some bracelets have a small size difference. This is what we call the beauty of defects. Just like liking a person, if you like him (her), you must accept his (her) shortcomings. No one is perfect, let alone a gem from hundreds of millions of years ago. Please understand natural crystals, take care of natural crystals, and hope that every crystal that belongs to you can bring you good luck.
