Surabaya is a complex and special geological phenomenon in jadeite, which is the product of epigenetic geochemistry. Its color is generally gray or blue-gray or green-gray, and the distribution is generally uniform. So how do we identify the jadeite? Next, the small series of China Jewelry Merchants Network teaches you a small trick, so that you can easily identify the water and jade.
How to identify drowning jade
1. The jade gravel is usually covered with a few meters of water. A ash, blue-gray or green-gray hull is generally called a blue water hull or black mullet. According to the hull and other features, it is easy for an experienced person to determine that it is jade. However, the color and texture of the interior of the jadeite that has not been soaked in water is difficult to judge from the husk. This is also the reason why there are great risks in blue-shell and black-shell gambling. And it's usually "ten gambling and losing".
If you often observe the cut water, jade and gravel. Because of its obvious, evenly distributed blue-gray tone, especially along the husk and the distribution of earlier cracks, it is easy to identify whether the bracelet, pendant and jade carving crafts are drowned.
If conditions permit. The jadeite jade sample can be cut into thin slices and identified under a polarizing microscope. Observe the characteristics of the fine fissure distribution of the iron leaf chlorite along the network in the jade.
Water jade bracelets, pendants, etc. On the polished surface, a 10 to 20 times magnifying glass was observed, and a small amount of inconspicuous fine mesh cracks were observed. It is treated like a slight corrosion of acid (B goods) jade. There are no signs of glue in the micro cracks. Data such as hardness specific gravity and spot refractive index are almost identical to those of A. Surabaya jade is still a cargo jade.
Jadeite composed of omphacite fine mineral aggregates. Often referred to as oil green is more appropriate. Lishui jadeite should not be called oil green, I think it is better to call blue water.
