Публикувано на от Кингджи

Opal is the gem with the most unique color among colored gems. Следователно, in order to increase the play-of-color phenomenon of opal, set off the play-of-color phenomenon better or fill the cracks of opal, the market will optimize opal, the main methods are as follows :

Sugar Treatment: Put the non-play-of-color opal into saturated sugar water or high-concentration fruit juice and heat it. След охлаждане, the carbonized sugar will show a play-of-color phenomenon. Saccharified opal can be observed under a microscope to see the black spots left by the carbonized sugar. Saccharification is not a difficult processing method, and it is easy to identify, so it is rare on high-priced opals.

Glue filling treatment: Glue filling is mainly to fill the cracks of the opal. The opal has low toughness and may crack due to the loss of water. Следователно, this treatment is very common, but because it is filled with resin-based glue, it is used in fluorescent lamps. There will be a fluorescence reaction, and the general laboratory can detect whether it has undergone this treatment. Разбира се, scanning the infrared spectrum of jadeite can also be used to detect whether it is a glued opal.

Plastic Impregnation: Inject black plastic filling into the loosely structured opal to make it look like black protein, making the low-quality opal look like high-grade black opal, which can be seen under the microscope Traces after plastic filling.

Sandwich Opal: Double-layer Opal Doublets is a white opal with a black bottom, usually black agate is used to set off the original white opal to make its play-of-color phenomenon better; a transparent crystal on the three-layer opal Triplets Or a thin layer of opal sandwiched between the glass and the black bottom underneath is called a three-layer opal. Because only a small part of mezzanine opal is real opal, the price is much cheaper than the whole piece of opal.

Artificial Opal Imitations: Compress the imitations of salty opals with synthetic materials, and carefully observe the play-of-color of the opal with a magnifying glass. The edge lines of the play-of-color are like snakeskin-like zigzags, which are artificial imitations. The only way to park man-made and natural.
