Emerald jade is recognized as a precious jade in the world, because it is naturally rich, noble and graceful green, and is favored by the East and West. Emerald jade production is scarce, adding to its unparalleled charm. However, it is precisely because of this that some unscrupulous merchants have moved the fake emerald jade to the market, disrupting the market. Forged emerald jade not only does not have the value of a true gem, but long-term wear can also hurt the wearer's body. So, how should we identify the authenticity of emerald jade?
There are some artificial imitations in the workshop. Although the color can also make dark green, it is not bright, and the reflection power is weak. The unique "wing" logo of the real emerald can not be created, and some only cause lace-like feathers. There are a few technically sophisticated, forged (flaps), and not linear slag, but a nearly circular or concentric arc, which has no shape under a twenty-fold magnifying glass. In fact, artificial fakes have appeared more than a hundred years ago, so do not think that antique emerald beads do not have artifacts.
After the middle of the 1960s, many synthetic products made in the United States and Germany were mixed into the market. They were free of natural cracks. They were too green and uniform, and there was no depth or depth. However, under the magnifying glass, specific growth patterns or halo-like melting were observed. Quality inclusions.
Also attached to the common emerald imitation -
Artificial glass
Green artificial glass is most similar to emerald, and it can achieve chaos in terms of color and appearance. Air bubbles in the man-made glass or some other residual material can create an appearance similar to a crack or fingerprint-like inclusion, but the man-made glass lacks the green fluffy feel of emerald. People who are more familiar with emeralds will have doubts about the glass at the first observation of the sample, but some yellow-green or blue-green emeralds have a lighter green luster and are not easy to understand. Special care should be taken when distinguishing from artificial glass.
2. Artificial garnet garnet
Artificial garnet garnet is also very similar to emerald, because artificial garnet is also a homogeneous body, and the difference is similar to the artificial glass step. Only the artificial yttrium aluminum garnet has a large refractive index, generally greater than 1.81, which is generally not measured by the refractometer, and the emerald can be directly measured at 1.575-1.583. The interior of the artificial garnet is generally clean and occasionally air bubbles. The absorption spectrum is different from that of emerald, and the artificial enamel garnet has no soft feeling of emerald green velvet on the naked eye.
3. Flatten the gem
Emerald flat stones come in many forms and can be split in two or three layers. The most common are grandmothers with beryl, emerald or beryl and green man-made glass, red garnet and green man-made glass, colorless crystals plus a layer of green material and colorless crystal. The top is usually emerald or beryl, and is lined with various green materials such as man-made glass, synthetic emerald, light-colored beryl, etc., which can be glued with colorless or green glue.
