All shades of green: emerald

Emerald is a gem, which is a variety of green. Natural precious stones can still be called a poetic word - Smaragd, that in the language of the ancient Rusich means - jewel. Color, as a rule, dark, dark green. Blue and yellow shades are allowed. There is also black emerald, but this mineral is a type of tourmaline, and he has little in common with Berillom. Find out what a genuine gem looks like, what is his story and whether it is possible to distinguish the fake from the original.

History of modern Emerada

The description of the Emerald is found not only in the Slavic chronicles, but also in the writers of ancient Egypt and Rome.

Cleopatra had its own large deposit of gems. The Egyptians believed that the stone gave them gods. He symbolized the spring and eternal youth.

Emerald appreciated in Babylon, India. Crystal was presented as a gift to high-ranking officials, wealthy people.

Have a decoration with a mineral meant possess a magical force. He was often given to beloved women. It was believed that the jewel decorated with this stone would save from the evil eye and damage.

Mankind is known many types of emerald. But only in the XIX century people opened the chemical composition of the emerald. Green beryl gives a saturated color of chromium oxide or vanadium. Allowed in the composition of iron impurities.

Where is the emerald in nature

Easmodes are produced in rocks. The largest natural stone deposit is located in Colombia. It is there that receive 50-95% of all minerals at the moment. Colombian Stone Emerald is considered one of the best all over the world.

Of course, pure green emerald is an excellent raw material for making jewels. It is framed in gold, silver and platinum. But unprocessed, unroquired crystals can be used to treat a person.

Their cost is lower, but lithotherapists believe that such gems:

• normalize pressure;
• get rid of headaches;
• improve visual sharpness;
• help in the treatment of diabetes;
• normalize metabolism.

Artificial stones

A simple formula of the emerald allows you to grow crystals in laboratory conditions. This uses emerald powder, water and special blanks. The technique is called - hydrothermal technology. Experienced specialists control the whole process (the magnitude of the stone, its color).

Synthetic gems for external signs are no different from natural. Their color can be different, green-white with dairy splashes to green-blue, but the main tone is green.

The density of minerals of this type is less, but the color is rich. There are copies of unique shades.

Made artificial gems in Germany, Switzerland, Russia, Belarus, USA.

How to distinguish artificial stone from natural

Chemical formulas synthetic and very similar.

But even with the naked eye, the stones can be distinguished:

1. Pay attention to the appearance of the gem. Too light emerald (almost salad) is the result of laboratory cultivation. In nature, the stone has darker shades, and dark green dominates. The brighter of the gem that suggests you, the greater the likelihood that this is a synthetic analog.
2. You need to pay attention not only on color. Emerald of natural origin has inclusions, small defects, cracks. They are quite acceptable. Artificial analogue grown in the laboratory will not have such defects.
3. With the help of a Chelsea filter. If you look at the artificial emerald through it, the stone will be much redest than natural.
4. Influence filtered UV (ultraviolet) irradiation with a long wave of 340-360 nm. Natural emeralds do not react to it, while synthetic acquire the characteristic luminescence of brown. But the technique is not perfect, as some natural minerals also react.

Price

Artificial gems are richer in color palette, but their cost, of course, is lower than natural.

An important factor affecting the price is cut. Glittering the edges of the stone, recalled in the precious metal, will cost much more than the untreated. Most often occurs the cut "Emerald", much less often - "Cabochon".
