2, thermal measurement: the needle burns in an inconspicuous place of amber, with a faint pine fragrance. Bakelite and plastic smell pungent and stick to needles. Friendly reminder: Too hot will leave black spots on the amber surface, which will affect the appearance.
3, nail polish lotion: repeatedly wipe the amber surface with a cotton swab, no obvious change. Plastics, pressure and amber have not changed, but resin and Coba butter will be corroded because they are not petrified, resulting in sticking pits. Rosin will melt slowly when it is soaked in liquid medicine. Friendly reminder: some amber has a layer of polishing substance, which will turn into white spots when wiped with drugs, but this layer of white spots can be scraped off with nail shells to expose the surface of amber, and there will be no change when rubbed with drugs. The liquid medicine still has 18%-20% solubility in amber, and the surface may become foggy after soaking for a long time.
4, feel: amber is a neutral organic gem, not very hot in summer, not too cold in winter, very gentle. Imitation with glass or chalcedony will feel cold and heavy.
5. Eye scales: This is the most important method to identify inlaid amber. Amber usually has beautiful scales of lotus leaves, which have different feelings from different angles, have different refraction and emit spiritual light. The transparency of fake amber is generally not high, and the scales emit dead light, which is similar from different angles and lacks the aura of amber. The scales and patterns in fake amber are mostly injection molded, so most of them are the same. The most common one on the market is the red scale.
6, ultraviolet irradiation: put amber under the money detector, it will have fluorescence, light green, green, blue, white and so on. Amber and Jin Po have the most obvious discoloration, while blood amber and beeswax have no obvious discoloration. The more transparent it is, the more obvious it is, and the plastic will not change color. Friendly reminder: don't test under strong light or the effect will not be obvious.
7. Sound test: Amber beads without inlay will make a very soft and slightly dull sound when they are gently rubbed in their hands. If the sound is plastic or resin, it will be crisp.
8. Spend money to identify: find a jewelry identification center with CMA qualification to detect the nature of amber, which is the most reliable result.
Note: The best test methods: visual inspection, ultraviolet irradiation, hand feeling and salt water. Other methods will do some harm to amber even if they are detected to be true. The above identification methods cannot be used alone, and various testing methods should be used to distinguish between true and false! I'm glad to answer it for you.
