Emerald
The bright green gem of the beryl and Maystone mineral family.
Colombian Emeralds:
Emeralds in calcite and shale matrix originate in the Coscuez basin, Muzo, Colombia. Crystal shaped with an attractive blue color is approximately 1 inch (1 cm) in diameter.
What are Emeralds?
Emeralds are high-quality images of a rich, green beryl mineral family. They are found in agneous, metamorphic, and sedimentary rocks in a small geographic area around the world.
For over 5000 years, emeralds have become one of the most beloved and important colored gemstones. Ancient civilizations in Africa, Asia and South America acquired emeralds independently and made them of great value. In the United States and many other countries, the emerald serves as a monument to people born in the month of May.
Today the emerald, along with ruby and sapphire, make up "three hundred" colored stones. The "Big Three" produces more economic activity than all other colored stones combined. In 2015 the number of emeralds imported into the United States surpassed the total number of colored stones except for the "three" included.

Emerald Physical Properties:
Color: The bright green color between green and yellow. Stones with a light tone or low satellite should be called "Beryl green" instead of emerald.
Intimacy Almost all natural emeralds have physical features such as inclusions, overlapping fractures, or cured fractures. Treatments to fill fractures with oils, wax, polymers, flux and other materials to reduce their appearance have been a common practice for centuries.
Luster Vitreous
Transparent Diaphaneity of light
Cleavage One direction of incomplete rupture.
The Durability Emerald is quite heavy, but almost all of the models have inclusions and accessible body parts that compromise their durability.
Weight of Mohs 7.5 to 8.
Specified deductions of 2.7 to 2.8
Chemical formulation of Be3Al2 (SiO3) 6.
Emerald green is caused by a certain amount of chromium or vanadium.
Crystal System Hexagonal. Usually as prismatic particles.
Emerald green color
Beryl, the mineral in which the emerald is varied, contains the chemical properties of Be3Al2 (SiO3) 6. When pure, beryl is colorless and known as "goshenite." Tracking the amount of chromium or vanadium in minerals makes it grow green. The values obtained by the metal will paint a blue-green or yellow-green color depending on its oxidation state.
Emerald is defined by its green color. To be emerald, the sign must have a green color that falls in the range from green to light green to light yellow. To be emerald, the sample must also be rich in color. Stones with weak satellite or light tone should be called "Beryl green." If the beryl color is blue it becomes "aquamarine." If yellow is "heliodor."
This color definition is a source of confusion. Which combination of hue, tone, and satellite saturation are the dividing lines between "beryl green" and "emerald"? Experts in the jewelery and jewelry trade would disagree about where the lines should be drawn. Some believe that the word "emerald" should be used in the description.
