Emerald (mineral name beryl), mainly distributed in Colombia, Brazil, India and other places. Emerald is among the top five gems (diamonds, red sapphires, emeralds, emeralds, cat eyes) with its glamorous charm.
Emerald, English (EMERALD) is called a bright green gem, the legend is derived from ancient Persian. At that time, the social transportation was not convenient, the mining technology was simple, and the output was small. Therefore, the emerald was only a luxury item for the official display. Because the original processing technology is not enough, it is difficult to show its best texture and the most beautiful colors. After a long period of exploration, people finally found that they must be cut into four steps, and the four corners are also grounded by one tenth, that is, the ratio of length to width is 1:1.5-1:1.75 (the approximate value of the golden ratio). Shape and cut work is called "emerald cut", and all those who conform to this shape are collectively referred to as "emerald cut" or "emerald-shaped gem". This cut perfectly reflects the emerald green.
The evaluation of emeralds is usually: color, transparency, cut, weight.
Color, distribution should be uniform, without impurities, pure green, dark green is better (not blue, not yellow). Transparency, internal impurities, cracks, defects, no scratches on the surface, and good residuals. The cutting work must be in proportion, the various processing surfaces should be regular, and the symmetry should be good. Weight, in carats, 1 carat equals 0.2 grams. Premium emeralds have the same value as diamonds of the same weight.
Emeralds are expensive, so imitations are constantly being used, and some are replaced with emerald-like gemstones. The natural emerald hardness is 7.5-8, non-homogeneous, with irregular cotton inside, containing three inclusions or comma-like inclusions. The color is calm, rich and restrained, and the surface is bright and clear. Here's a simple comparison of other green gemstones with emeralds:
Green tourmaline: hardness 7 grade, yellowish gray and dark, no three-phase inclusion inside.
Jadeite: Hardness 6.5, grease to glass luster, translucent to opaque, fiber interweaving structure, color mixed with the gemstone body, no three-phase inclusions.
Green glass: Hardness grade 5, frivolous color, lack of emerald green color features, contains bubbles inside.
Emeralds are similar to other gemstones, and some are also defective. In order to enhance their natural beauty and increase their value, emeralds with some light, light and cracked emeralds are soaked with vegetable oil and cedar oil to make them perfect. In addition, there are emeralds filled with resin-based transparent glue, but under the magnifying glass, it can be found that the thicker parts of the filling will leave bubbles and the gloss is gray. In order to make the emerald color deeper, it is dyed with chemical pigments, but under the high magnification magnifying glass, the green inside of the distressed emerald can be seen along the network of cracked spiders.
