custom green tourmaline rings Baolong Sharing: Identify gemstones by visual and tactile inspection

Let’s observe the surface gloss of gemstones. The higher the hardness of gemstones, the higher the surface gloss will be after polishing. The gloss of diamonds is the best among all transparent gemstones. It is diamond gloss. Most other transparent gemstones are glass gloss, which is lower than glass gloss. Most of the gems have a low hardness, о 5, such as serpentine. Следующий, check the cutting of Qi. All gems have a typical cutting method. Although there are exceptions, the cutting of gems will be selected according to the transparency of the gem. Only those with high transparency will be cut into faceted gemstones. The less transparent ones are mostly egg noodles (Cabochon) or engraving. Check the transparency of each gemstone. What kind of cut should be done. Например, diamonds focus on their clarity and cut, so they are cut into special brilliant cuts. The transparency of jade or nephrite can only cut salted egg noodles. Цвет, блеск, and cut will reveal information about the characteristics of the gemstone and provide preliminary information for gemstone identification.

Touch

The cold touch of natural gemstones cannot be shaped by man-made synthetic gemstones, but the difference in temperature is very small and requires accumulation of experience. The most sensitive parts of the human body to temperature are the fingertips and the lips, so you can use these two places to feel it. The famous gemological authority Mr. Gubelin once gave a speech onThe Method of Identification of Gems without InstrumentsMentioned inGive your gemstone a first kiss.” (Give your gemstone a first kiss.), this is the truth. Например, the cold touch of natural jade is different from other imitations and you can feel it by touching it with your hands.
