Amber - fossilized fossil resin, hardened resin of the most ancient conifers of the Upper Cretaceous and Paleogene periods. Mainly used for making jewelry and haberdashery, bijouterie

Experts distinguish about two hundred and eighty varieties of amber , from "sea" to "earthy", which are found on the Amber Coast. Amber also characterizes the degree of transparency associated with the unequal concentration of microscopic voids in its body. On this basis amber can be called:

  • "transparent" - no voids, superior quality
  • "cloudy" - translucent, with a cavity density of 600 / mm2
  • "bastard" - opaque, with a cavity density of 2500 / mm2
  • "bone" - opaque, resembling ivory in color, with a cavity density of 900,000 / mm2
  • "frothy" - opaque, externally resembling pestilencefoam, with a variety of cavities from the smallest to very large, a few mm

Amber is also distinguished by color: shades of amber are no less than colors in the spectrum. The reason for this diversity is usually the presence in the body of amber substances and minerals foreign to the resin.

Amber is a fragile material, its processing leads to a significant reduction in the primary size and weight of stones, which in turn leads to an increase in the cost of jewelry. Currently, there are processing technologies for giving amber the desired color and texture: clarification, heating, heating, chemical processing, grinding, cutting, stone carving and others.

Also worth noting is pressed amber . When heated, pieces of amber become very plastic. This property is used in hot pressing, when ground into a powder is naturalth amber is sprinkled into molds. Under the influence of temperature and pressure, the powder turns into a viscous mass. After cooling and hardening in figured shapes, pressed stone products are obtained. The stone obtained in this way was named " ambroid ". Amber powder can be mixed with various dyes, which makes it possible to obtain bright contrasting colors (white, black, red) and shades close to natural (translucent greenish, cherry).

First of all, it is necessary to understand the difference between counterfeiting and deep processing of amber using innovative technologies. Pressed amber is made from 100% natural raw materials, imitation and falsification of amber - from materials with a minimum content of amber raw materials or without it. imitation amber made of epoxy resin, in whichoften some kind of "fossil" insect is introduced. Currently, there are many plastics that very well reproduce the basic properties of natural amber . Imitation amber made of plastic and amber dust.

bernite - a kind of artificial "fused »Amber from various resins. Bernite consists of polyester resins with amber content up to 5% or even without it, imitating the structure of hardened amber and obtained using the "micro-explosion" technology to create decorative internal cracks.
