Can Emerald still be grilled? Many people feel quite surprised, but insiders will smile when they hear this, because they are talking about a jadeite optimization method in the industry - burning red jadeite, have you ever bought it? It is the red jadeite in the picture below!
Emerald jadeite, red and yellow for emerald green for jade, jadeite for jadeite, because of the surface of jadeite rough, after thousands of years of underground mineral immersion, by the secondary iron oxide influence, the formation of brownish yellow or brownish red, generally under the shell of jadeite rough, jade flesh, also known as red mist layer, the general emerald color is relatively dark, not bright enough bright and bright, so many people will use heat treatment, give jadeite barbecue, a very magical situation happened, the original dark brownish yellow will turn into bright red, What we call "burnt red emerald" is out of the pot!
Many people say that such artificially processed jadeite should not be natural, it is really not! In the process of heat treatment, the elements inside the jadeite are only the price state has changed, the composition and structure have not changed, belongs to the optimization category, even if it is known to be burned red, take it for identification, you can still issue a natural jadeite certificate.
Burn red on the left and natural on the right
So how to identify such burnt red jadeite? From the texture point of view, during the heating process, the original secondary impregnated gelatinous limonite minerals lost part of the adsorption water, gradually crystallized, into a small collection of microcrystallines, the loss of water and the transformation of the phase, will make the jadeite particle gap is exposed, resulting in many fine cracks, the texture also becomes rough, the transparency is reduced, and the delicate texture of itself is lost.
Natural emerald color
From the color point of view, the natural red emerald color is gray, the color has changed, with a sense of layering, the color of natural red jade and white, purple, green, etc. is a mutated relationship, and the jade flesh boundary is clear; the color of burnt red jadeite is more vivid, but there is no sense of layering, it looks relatively single.
Although the burnt red jadeite can also issue a certificate of natural jadeite, but after all, after manual treatment, for lovers of pure natural and pollution-free jade, they always feel that they can't get over it, so if you see a particularly bright red jade, you must keep a snack to see if it is baked by the merchant with cumin and pepper!
