As the amber market continues to rise, and the number of people collecting amber is increasing, the phenomenon of jewels in the jewelry market has occurred. Some merchants are selling synthetic pressed, coba resin and even plastic forged amber jewelry and amber rough, those posing as amber. The original stone of Coba resin, because of its low price and the buyer can directly participate in the polishing, has attracted many unsuspecting ordinary collectors to participate in the "amber" jewelry polished by themselves, but they do not know the quality of Coba and amber. Prices vary widely. What is Coba resin? Coba resin is a natural resin in the semi-fossil state that was produced between millions of years and modern times. Its texture and appearance are similar to those of amber, but it has not been formed for a long time. Therefore, it is called “recent resin†in the industry. The physical properties of Coba resin are unstable, and it is easy to ablate when exposed to heat. However, the so-called amber jewelry made of this material is extremely deceptive and easy for the first-time person to be fooled. What is amber? Amber is an organic colloid that flows out of the bark of pine trees thousands of years ago. It is a natural fossil that is deeply buried in the earth's crust and gradually condensed into the ground. It often contains various insects inside. Such as spiders, ants, mosquitoes and seeds, charred leaves and so on. Most of the color of amber is golden yellow. There are more than 100 types of amber in the world. The amber of the Baltic countries in Europe is the most famous. The amber produced by the coast of the former Soviet Union accounts for 90% of the global total. In recent years, Myanmar amber has become the new favorite of the industry for its unique quality. How to identify Coba resin? 1. Coba resin is very smooth because it is soft in texture. 2, Coba resin due to the extremely low degree of petrochemical, the content is usually white, so insects. 3, Coba resin due to the short period of time, the color is usually very shallow, the contents do not have the unique oak hair of the Baltic amber. 4. Apply an organic solution such as alcohol or ether to the cotton swab to wipe the surface of the coba resin, which will make the polished part lose its luster. 5. After the organic solution such as alcohol or ether is dropped on the coba resin for 30 seconds, the coba resin will be corroded and become sticky.
