Green price In recent years, the current production of Green Perth is very small, so the price of Green Perch is relatively high in amber. The price is lower than that of the blood and the blue, but it is not much different. Can appear in China, the basic price is about a thousand or so. Green Perg refers to the appearance of pale green amber in the interior, mainly in Romania, South America. Most of the green pepo samples in the market are yellow-green, green, and some have uneven color. Green almost completely penetrates small samples, but only exists on the surface of larger samples. Even some samples are very clear, with a few disc cracks (so-called sunflower or popcorn) and very few bubbles. Almost no plant debris was found, and granular granules were observed under professional microscopes with microscope and fiber optic illumination. The hardness of the all-optimized sample is close to that of amber (2-2.5 Mohs hardness), and the sample shows a slight white and dark green under long- and short-wave ultraviolet radiation, which is one of the signs of heating. They produce static electricity, feel warm to the touch, and have cracks on the surface and a slight odor. Greenpeer identification method 01. Saline test method: In the brine of 1:4 (salt: water), both resin and amber can float, the plasticity plastic floats, and the ordinary plastic sinks. Note: Amber with insufficient brine concentration will also sink. The mahjong of the house is hollow and the air is floating on the surface. 02. Thermal test: Burn the needle to the invisible part of the red thorn amber (for example, at the small hole of the bead), which has a light and loose flavor or no taste. Plastics can smell and stick to needles; in less than a year, coba or rosin needles can easily melt and insert into the scent. The difficulty of needle insertion is felt by experienced professionals. Note: Improper operation will leave amber spots on the amber surface, which will make the amber ugly. 03. Needle-cutting test: The cutting knife will cut into a powder, the resin will fall off in pieces, and the plastic will become a roll. A 30-degree angle with a hard needle and a horizontal line will have a bursting feel. Note: This test will cause damage to your jewelry. If you pick up the cut-out, you can only find a professional to repair it. The owner almost ruined a feathered Perth, and the pick was too fierce. 04. Nail Polishing Lotion: Wipe the amber surface repeatedly with a cotton swab and it should be unchanged. There is no change in the plastic and the pressure and the amber, but the resin and the coba are corroded to form a sticky pit because there is no petrochemical. The rosin is put into the syrup and it will melt slowly. Note: Some layers of glazing material outside the amber will become white spots when wiped with the potion, but this layer of white spots can be scraped off with a nail shell to expose the amber surface, and the potion is wiped on it without any change. The syrup will still have a degree of melting of 18%-20% for the amber, and the surface of the bubble may become foggy. 05. Feel: Amber is a neutral gem. It won't be very hot in summer, and it won't be too cold in winter. The general situation is mild. With glass or chalcedony, there will be ice and ice. 06. Eye-view scales: This is the main method for identifying silver-set amber. There are usually beautiful lotus leaf scales in amber, which have different feelings from different angles, and the refractive power will not be the same. The transparency of fake amber is generally not high, and the scales emit dead light. The observation from different angles is almost the same, lacking the aura of amber. The scales and patterns of fake amber are mostly injected, so most of them are the same. The more common ones are red scales. 07. Eye bubbles: The bubbles in amber are mostly round, and the bubbles in the pressed amber are mostly long. 08. Cracked weathering pattern: The back of the green pel is generally treated with red or black. A crack in the turtle can be seen under the naked eye or under a magnifying glass. 09. Ultraviolet radiation: A simpler method is to put amber under the detector, which will have fluorescent, light green, green, blue, white and so on. The plastic does not change color. 10. Rubbing with static electricity: Take amber on the clothes and rub it to attract small pieces of paper. 11. Spend money to make an appraisal: I got the CMA Jewelry Appraisal Center to measure the refractive index. I didn't see the appraisal book. If I can find the density and the age, it will be perfect. The preferred test method: eye, ultraviolet radiation, hand, salt water (limited to bare stone, not 100% accurate), other methods more or less even if the amber is true will cause certain damage to amber, one Beautiful jewelry can only be a poor waste.
