How to find Emeralds in the earth
You can check an Emerald for authenticity by checking what fluorescent colors can be seen through the gem with a blacklight. A natural emerald will show a pure green or blue-green hue. With the light, it will either not have any backlight or a weak orange-red or green color
Beryl is a rare mineral with a chemical composition of Be3Al2 (SiO3). This is rare because beryllium is an element that occurs in very small amounts in the earth's crust. It is not unusual for beryllium to be present in one location to form minerals. In addition, the conditions in which beryllium is present in a number that is significantly different from the conditions in which chromium and vanadium, sources of emerald green, occur. This is why emeralds are rare and are only found in a small number of locations.
Although the conditions of the Emerald formation are very difficult, these gems have been found in a variety of rock types. In Colombia, the country that supplies most of the world's Emeralds, black organic flakes and sparkling limestone, both sedimentary rocks, are ores for many Emerald deposits. This flake is considered a source of chromium, and beryllium is considered to have been delivered by ascending fluids.

Many world Emerald deposits have formed in the contact metamorphosis area. A granite magma can function as a beryllium source, and a nearby carbon fuse or seam can function as a source of chromium or vanadium. Emerald usually forms in schist or gneiss or on the edge of the nearest pegmatite. Mafic and ultramafic stones can also function as sources of chromium or vanadium.
Emerald is rarely mined from alluvial deposits. Emerald is usually a cracked rock that has no alluvial power to survive far from its source. Emerald also has a specific gravity of 2.7 to 2.8, which is not significantly different from quartz, feldspar, and other common materials found in current sediments. Therefore, not concentrating with high density granules separated in the current and more easily recovered by placer mining.

The largest emerald deposits are currently mined in Colombia, Brazil and Zambia. Emerald is mined throughout the world (Pakistan, Afghanistan, Russia, Australia, United States) but these are the three main sources.
Colombia arguably produces the best emeralds. Brazilian emeralds tend to be brighter in tone and more are included Inclusions (Fiber Stones). Inclusion in Emerald Brazil may be a dark inclusion, where brightly colored inclusions that are usually in Colombian Emerald (known as jardin) are considered to be less factors that have a negative impact on their value.
Emerald tends to have more bluish streaks than Colombian or Brazilian emeralds, and tends to lead to a rather gray cast, which is not in the Colombian Emerald or Brazil. Zambian Emerald and Brazil can also be colored due to vanadium, while Colombian Emerald usually reaches its coloring from the presence of chromium.
Chivor and Muzo are the two main mining districts in Colombia. Chivor, northeast of Bogota, is in a very rough area with dense forest vegetation. The two main mines in this district are Chivor and Gachala. In this area, these rocks are mainly shale and sandstone. Emerald crystals can be found in blood vessels containing pyrite, quartz and albit.
Muzo is the most famous mining district in Colombia. Located 60 miles north of Bogota. The climate is hot and humid with continuous rainfall. Muzo, Cosquez, and Pena Blanca are the main mines. Emerald crystals can be found in deposits of calcite in shale.
Most of the Emerald that we offer comes from Colombia, because this tends to have the most accepted popularity and represents the best value for our Customers.
