Advice for your choice:

It is considered from factors such as color, position of eyeliner, shape and weight of gem. High-quality cat-eye gemstone, the cat-eye line should be thin and narrow, and the boundary should be clear; Eyes should be flexible to open and close, showing vivid 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 cambered surface. When purchasing, we should distinguish opal from other precious cat eyes and artificial cat eyes according to the identification characteristics, and purchase genuine opal.

Like other gems, the bigger the opal, the harder it is to find, so the weight is still one of the basic factors to evaluate opal. But the most important factors affecting opal are color, eyeliner and uniformity.

The best color of opal is very strong yellow-green, brown-yellow and honey-yellow, followed by green and then slightly dark brown. The values of extremely white yellow and extremely white green are low. The worst are variegated and gray.

The best opal eyeliner should be narrow, with clear boundaries and vivid light, and should be located in the center of the gem. Regarding the color of eyeliner, some people like the silver forehead color, others like the golden yellow color, while the green and blue-white lines are relatively ignored. People with opaque gray body color often have blue or blue-gray eyeliner. However, no matter what color it is, it is important that the eyeliner contrasts with the background and looks clean. Keep your eyes wide open, the bigger the better, and be sharp when you close them.

Processing technology (especially the degree of symmetry) is also an important factor in evaluating opal. In order to make full use of the original stone, the purpose of keeping it thick is to increase the weight and sell more money. However, the result was just the opposite, which seriously affected the beauty of the cat's eye and no one paid a high price. The correct way is to keep a proper thickness below the waist line of the gem and polish it into a small arc surface. Keep the angle low, so that the gem can be firmly embedded in the holder.

1. The main feature of opal is that it can see a clear brown cat's eye. The spun silk inclusions of opal are rutile and hollow tube. Because these tubular inclusions are slender and dense, the cat's eye effect is particularly obvious even under weak light source. This is unmatched by other gems.

2. Artificial opal is made of glass fiber, which is red, blue and brownish yellow, and some brownish yellow varieties are very similar to natural opal. The difference between the two is that artificial opal has 2-3 bright bands at the arc top, while natural opal has only one; Observing the two sides of artificial opal with a magnifying glass, we can see the hexagonal honeycomb structure; Meanwhile, the hardness of artificial opal is lower than that of natural opal.

3. Illuminating from the side of opal with a single light source, the colors of both sides of opal are different. When the honey yellow opal is illuminated from the left, it is honey yellow on the left and milky white on the right. When illuminated from the right, its color is just the opposite.
