Natural gemstones are always more or less with enamel, so that the gem world has the saying of "Ten Treasures and Nine Cracks". Of course, natural amber is no exception. The broad meaning of ç‘•ç–µ refers to all the defects of natural gemstones. In the narrow sense, it refers to the small impurities, cracks and other impurities in the gemstone crystal. The following small series will tell you about the common cockroaches in natural amber.
A few common cockroaches
1, dirty spots. It refers to the presence of speckled, small, long or braided black or other dark impure inclusions inside the crystal of transparent amber, such as carbonaceous materials, small collections of dark minerals, etc. This is natural amber. There are often, and some have small bubbles.
2, cotton willow. Also known as "waist", it refers to the small and smooth silky cotton, cotton, willow or catkin-like material inside the transparent amber crystal, as well as the flower-like pattern, often referred to as "filament". "Flap", "flower", "small flower" and so on. The formation of these substances may be due to the presence of inclusions or the influence of external forces on amber crystals, such as "Liu", "Sunflower", etc., which are often referred to by amber artists.
3. Fine cracks. As for the fine cracks in the amber crystal, it may be naturally formed, or it may be caused by artificial factors during mining, processing or otherwise.
And now the old craftsmanship has been upgraded, especially beeswax. Specifically, there is a large piece of beeswax with cracks and cracks, which are turned into cracks and pits, and then filled with amber powder, and then into the furnace to do the same process as the overall heat treatment. In fact, a similar process has been done before, but other substances such as adhesives need to be added, and no other substances need to be involved. And now the price of amber beeswax is high, so the complicated process cost can be sold, especially the grinding into beads and then baking, after baking, the naked eye can hardly be seen.
The cost and quality of the pressed and dewaxed beeswax cannot be compared with natural beeswax, and many consumers often purchase such pressed beeswax at the price of natural beeswax, which invisibly damages their interests. Be careful when you need to get a professional appraisal agency for identification.
