Amber is the resin of Fossil from a pine tree which flourished and grew in full swing in the Baltic region or other localities about 25-60 million years ago. Different globs from this aromatic material/sap or piece poured down from ancient trees. They often trapped leaves, bark, twigs and insects. Amber is one of the rare and handful gemstones having an organic origin. In pre-historic Egypt and India, people used amber for burning as incense. They believed it to purify and cleanse the surrounding area. The material is found in abundance along the Baltic Sea shores.
People have extensively mining it from Tertiary glauconitic sands, which are roughly 40-60 million years old.
- The diagnostics: Often, amber is difficult to separate from its various imitations owing to the overlapping optical and physical properties. If no internal features remain diagnostic, you can usually resort to destructive methods like aceton or ether or hot needle test.
- The color semblanc: Amber stones come in a variety of colors. These are white, red, and brown, yellow, green, blue, black, and red, orange, white and contain a typical and unfettered resinous luster. You can find green and blue amber in the Dominican Republic. This Green or Blue color is only perceptible in the reflected light. You will see more of a common color of amber in transmitted light. These colors are red, orange and yellow.
- The color segregation: These blue gems provide a strong florescence of cobalt blue. The amalgam of these colors in the gems is regarded to be a product from the fluorescence of violet light and UV rays from natural sunlight. Delocalized electrons on different organic modules are another reason behind these colors.
- Specific gravity: IT varies from 1.05-1.09. The gem has many gas bubbles in its lower range. It floats in a saline solution, which is saturated. This is the prime reason you can find amber on different shores surrounding the Baltic Sea. It also floats finely on sea water. Pertaining to refractive index, some plastics and copal also fall in the identical range.
- Magnification and electricity: insects and other fauna and flora that get trapped in the resin are molded in plastic. These insects are generally extinct species. The green term for Amber is electricity or electron. The gemstone thrives on this name. If you rub it silk, it gets a negative charge of electricity while the glass gets charged positively charged. You can also charge plastics negatively like this.
- Different treatments: The different bubbles in Amber stones entail a hazy appearance. You use slow heating, followed by slow cooling for diffusing these bubbles. When it happens too rapidly, you have typical leaf-centric stress inclusions forming sun spangles. Other treatments include foiling, coating and dying.
Limitations on the front
When you're talking about reconstructed amber as an example, you have the inference of amberoid. You select clear fragments and heat them under a specific temperature. It reduces atmosphere with linseed oil being added. These gemstones have a tendency of whitening with time, as opposed to any natural amber that actually darkens.
