First of all, I would like to remind you that some small traders steal the concept, bind non-fossil resins to synthetic materials, especially call baked wax old wax, and the price difference is great.

Amber is a prehistoric fossil of turpentine, which was formed 40 million to 60 million years ago. The main components of amber are carbon, hydrogen, oxygen and a small amount of sulfur. Hardness 2-3, specific gravity105-10, melting point 150c- 180a. Amber is a very astringent substance. No two amber pieces are exactly the same. Its composition and structure can be identified by scientific instruments. Amber is generally identified by its low specific gravity and hardness, in addition, its refractive index is also very special.

In the actual collection appreciation, playmaker summed up the identification method of 12, so that you can identify the authenticity:

0 1 brine test method: the density of amber is between 105- 1 10. In 1: 4 (salt: water) saturated brine, amber, light plastic and resin can float, while ordinary plastic, glass, acrylic and bakelite can sink. Friendly reminder: this method is limited to naked amber. Amber with a lot of impurities in its body will sink if the salt water concentration is not heavy enough.

Thermal measurement: the needle was burned 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.

Needle picking test with a knife: cutting amber with a paper cutter will powder, resin will fall off in pieces, plastic will roll up, and glass will not be cut open. When you flush amber with a hard needle at an angle of 20-30 degrees from the horizontal line, you will feel explosive and there will be extremely fine powder residue. If it is plastic or other substances with different hardness, it will not stick, or it will feel sticky, or even stick in. Friendly reminder: this experiment will damage your jewelry. If you pick out the cut part, you can only find a professional to repair it. It is best not to do it or do it less, so as not to cause harm to amber.

04 nail polish remover: wipe the amber surface repeatedly with a cotton swab, with 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)

Feel: Amber is a kind of neutral organic gem, which is not too hot in summer and too cold in winter, so it is gentle. Imitation with glass or chalcedony will feel cold and heavy.

Observing scales with eyes: This is the most important way 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.

Observation of bubbles: bubbles in amber are mostly round, while bubbles in pressed amber are mostly long and flat.

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.

9 fragrance: amber has only a faint smell, and it can hardly be smelled when rubbed, or it can't be smelled at all, but amber with skin will produce fragrance when rubbed, and Xiangpo will produce fragrance when rubbed. Amber only gives off a loose fragrance when it burns. Friendly reminder: there is no rubbing smell on the stall, so it is better to just watch and not buy.

10 sound test: amber beads without inlay will make a very soft and slightly dull sound when rubbed gently in your hands. If they are plastic or resin, the sound will be crisp.

1 1 Friction with static electricity: Amber can attract small pieces of paper after rubbing on clothes. (Friendly reminder: except copy paper)

12 Expensive appraisal: Take it to CMA Jewelry Appraisal Center to measure refractive index, density, etc.

But the most reliable identification method is to go to the geological department for testing in person! There is no such thing as "undetectable"-even if the so-called "Middle East beeswax" appearing in China in recent years is not hot enough to attract the attention of the testing department, it can at least tell the buyer the actual composition of the Middle East beeswax. 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 hope my answer is helpful to you!
