The process is slow and energy intensive and the yield of facetable material is low.
What do emeralds look like in real life.
The mining area is literally shaped like a pit that can hold equipment and workers.
In the open pit mining method a lot of waste rock must be hauled away.
The methods used to create them in labs require expensive equipment.
Keep in mind however that synthetic emeralds can also look very clean and be quite affordable although they are not technically considered.
Like cut emeralds raw emeralds can be transparent or translucent a quality that is sometimes called clarity but in the gem trade is referred to as diaphaneity.
Emerald is a cyclosilicate.
In contrast to real emeralds artificially created imitations usually look too perfect and clean and if they are also relatively cheap then this is a giveaway sign that you may be dealing with a fake.
You can also tell if an emerald is real by looking at its edges.
Another test you can do to determine a natural emerald is to apply oil to.
Most emeralds are highly included so their toughness resistance to breakage is classified as generally poor.

If it reflects the different colors of the rainbow it isn t a real emerald.
The first thing to look for are tiny flaws or irregular patterns.
A real emerald has sharp defined edges so if the edges you re looking at are dull and worn it s likely not a real emerald.
Workers dig a large pit about 12 meters deep and then blast the surface with water to reveal mineral bearing rocks.
Raw emeralds like cut emeralds are all green but the shade of green varies from blue green to pale yellow green to a rich forest green.
Emerald is a gemstone and a variety of the mineral beryl be 3 al 2 sio 3 6 colored green by trace amounts of chromium and sometimes vanadium.
Beryl has a hardness of 7 5 8 on the mohs scale.
There are two main things to look for in natural emeralds.
