Amber itself is an organic gem, which is changed from the resin secreted by an ancient conifer. Mainly produced in the Baltic coast of Europe. Pure amber can only be used for a single purpose in jewelry processing, and its scientific value lies in the impurities contained in amber, especially the well-preserved insect remains. Generally speaking, amber containing ordinary insects has low scientific value, but it is still a good choice as a collection. Amber, crystal clear and delicate in color, is very popular in the world. Legend has it that amber was changed from the tears of the ancient Greek goddess Helitis. In our country, amber is regarded as the change of the soul after the death of a tiger. Amber is actually a petrochemical product of plant resin in geological age, and it is a well-preserved solid biological fossil. It is one of the organic gems. Amber is amorphous and irregular, ranging in size from fine particles to chunks weighing several pounds. The raw material has a resin luster, and after polishing, it has a resin luster close to glass luster.

The hardness is only 2-2.5. It is easy to cut with a knife, with poor toughness and shell-like cracks. The specific gravity of transparent amber is about 1.05 ~ 1.09, while the specific gravity of turbid amber is as low as 1.0. The refractive index of amber does not change much, but it is usually close to 1.54, which can be as low as 1.539 and as high as 1.545. Because amber is an amorphous substance, it is isotropic, cleavage-free, multi-colored and refraction-free. According to the lack of toughness, powdery inclusion, oily luster, broken glass and lack of high polishing ability, it can be identified as fat amber. There are often inclusions in amber, such as insects, seeds and other foreign bodies, which are captured before turpentine hardens. Germans call amber a burning stone because it burns at a very low temperature. For this reason, amber is often used as hygienic incense. Amber has rich colors, diverse patterns and strong or weak transparency. People give them many image names according to their different characteristics: Shipo, Huapo, Shuipo, Jin Po, Lingpo, Mingpo, Xiangpo and Xuepo. Among them, red blood beads are the most precious, followed by yellow transparent Jin Po, and goose yellow wax beads are the least. In real life, amber has various uses. Amber is often processed into decorative handicrafts such as necklaces, collars, rings and knickknacks. People wear them on their bodies, saying that they can "calm the five internal organs, calm the soul and drive away ghosts and evil spirits." Some ethnic minorities in our country must put amber necklaces on their brides at weddings. They think amber can make the bride and groom feel harmonious and stay young forever. In interpersonal communication, amber ornaments are noble gifts for relatives and friends, and both parties will feel that they are worth a hundred times. Amber can be used not only for decoration, but also for making medicines, dyes, spices and paints. Amber is generally identified by its low specific gravity and hardness. In addition, its refractive index is also very special.
