Postado em por Kingjy

Amber is an important category of organic gems, which can be made into rings, pendants and other jewelry for sale.

Immerse in oil and heat to make the color of amber more golden and dazzling, or change the originally low-permeability beeswax into crystal clear golden amber. This treatment is quite durable and stable, but the amber may become more fragile. , Heat or pressure may cause chipping. The identification of this treatment requires a magnifying glass to observe the inside of the amber to see if there are sequin lines produced after heating.

Synthetic amber: an artificial product made of synthetic resin, vidro, plastic, etc., which can be easily distinguished by specific gravity. Geralmente, these products have a higher specific gravity than natural amber and sink in saturated salt. Natural amber will float.

Copal Copal is a new resin made of the same material as amber. It is called Coba on the market. Because it is a product of resin hardening, the specific gravity is the same as that of amber, but the age is much less. The real amber must be buried in the ground. For thousands of years, Coba is a resin fossil formed in modern times. The age is usually very short, even less than a thousand years. Portanto, the texture is relatively fragile. It needs to be identified as Coba or amber based on its age and content. The price of Pakistan is much lower than that of amber.

Re-made amber Amberoid is to heat and dissolve the finely divided amber, then press it with hydraulic pressure to re-press salty lumpy amber. Sometimes linseed oil is added during the pressing process to make the color stronger. This re-made amber will destroy the natural The rhyolite structure during the formation of amber can be observed with a magnifying glass to identify whether it is natural amber or remade amber. The price difference between the two is also very large.

Natural amber will float in saturated salt water, which is the best identification method; além disso, the pine aroma produced by rubbing amber is also a good way to determine it. De um modo geral, Coba does not emit natural pine aroma compared with remade amber. No entanto, the most correct identification is to observe with a magnifying glass.
