History of use

What does a natural emerald stone look like?

Natural emeralds have a rich, intense green color. The mineral is a very light shade and is ordinary beryl. The following steps allow you to identify a fake:

  • Check under the Chelsea color filter. Natural stone will appear reddish-brown when viewed due to the presence of chromium in the composition.
  • When viewing the stone through a magnifying glass, small inclusions are observed. The peculiarities of the formation of an emerald are reflected in its internal state. Inclusions give the gem its uniqueness.
  • Use a refractometer. A natural gem has a refractive index of 1,58, while for a synthetic stone this indicator does not exceed 1,572.
  • And the most effective way is to take the product to the laboratory, since synthetic stones have become very similar to natural ones and it is not possible to distinguish without microscopy

Place of Birth

Some of the best colored emeralds are mined in Colombia. Colombian emeralds are a brand name in the gemstone world, synonymous with high quality. Specimens of excellent color also come from other deposits. For example, from Afghanistan, Brazil or Zambia. Small-sized raw materials are mined in Pakistan.

In Russia, the green beryl deposit is located in the Middle Urals near the village of Malysheva. They are mined together with alexandrites. But Ural emeralds are quite difficult to find on the world market. Today, most crystals come from Colombia and Zambia, where the largest gem-quality stones are also found.

History

The history of the stone begins in 330 BC, when the development of emerald mines began in Egypt, which continued until the 1700s. Queen Cleopatra used them to create her jewelry. And the Roman scientist Pliny the Elder described its physical properties back in the 1st century AD, noting that people use green emeralds to relieve stress and eye fatigue when looking at these stones. The history of the gem is also connected with the Incas, who used jewelry with emeralds in their religious rites. The Spaniards exchanged precious metals for Incan emeralds, which they then brought to Europe and Asia. Legend has it that the emerald was one of the four precious stones given by God to King Solomon. These are some of the most popular gemstones these days, with their spring green color attracting many.

Ennobling

More than 90% of emeralds on the world market are treated to improve their purity. To do this, the cracks are filled with cedar oil or various polymers. Oiling is considered a standard classical type of processing. Filling with colorless oil is allowed, but green oil is not approved by the gemological community. Staining with various types of dyes is sometimes used for almost opaque light-colored beryls. Refined samples are several times cheaper than non-refined ones. The cost will also depend on the degree of filling with various substances. Filling can be diagnosed by spectra, when other chemical impurities related to the filler and not included in the emerald formula can be seen in the composition of the emerald. The more aggregate there is in the stone, the lower the price will be.

Every year, jewelers create new stunning jewelry with emerald. But with the advent of new technologies, jewelry with fake stones is also appearing. To recognize the authenticity of a mineral, they pay attention not only to the price, but also to other criteria.

Ways to fake emerald

Emeralds are counterfeited in several ways:

  • imitation;
  • doublets (triplets);
  • synthesis of stones.

Often other stones that are similar in color and shade are passed off as emerald. For example: demantoid, tsavorite, green quartz, tourmaline, green jade, peridot, other minerals and green semi-precious stones.

Doublets and triplets are when several stones of different quality are glued together and combined with green paste. Sometimes, to make it more believable, real emerald fragments are glued to the surface of the jewelry.

The third method of counterfeiting is synthesized stones. Indicators of hardness, strength and light reflection of real stones are higher. Although the fake is similar in hardness to a real emerald, its shape and structure are softer.

Methods for identifying a real stone from a fake

There are 6 main criteria that help distinguish a real emerald from a fake:

  • Colour;
  • the presence of defects;
  • inclusions on stone;
  • strength;
  • clarity edge;
  • stone processing.

Jewelry with emerald has a beautiful, green color. This is because it contains chromium, which gives the green, rich shade of young grass. A fake will show a yellowish tint when the stone is held up to light or sunlight. Shine is also important, which is present only in genuine emeralds.

Products with green emeralds have defects. To prevent them from being visible, jewelers give them a hemispherical shape or make a stepped octagonal cut.

The third criterion is the purity of the stone. Fake emeralds are perfectly clean, while on genuine gems, when held under a lamp or sunlight, some gaseous, liquid or solid inclusions are visible. Doublets also have inclusions where the stones are glued together. Here you need to be extremely careful not to confuse a real emerald with a fake.

Real gems are durable, ranging from 7,5 to 8 on the Mohs scale. This is two scales less than diamonds.

The edges of a precious mineral have a clear outline, while those of a fake have a softer shape.

To improve a natural emerald and hide all defects, the stone is treated with a special green pigment or colorless liquid, as well as cedar oil. Fake stones are not processed this way; they already have a smooth structure without any defects.

All natural stones have a certificate of authenticity. A gemologist by profession checks the stone for authenticity.

What determines the cost of a real emerald?

Jewelry with emerald costs differently; the cost of such products is influenced by a number of factors:

  • emerald deposit. The birthplace of emerald is considered to be India, Pakistan, Egypt, and the Urals. Each specific region or country has its own inclusion. For example, gems from Colombia have a beautiful bright green color and very small inclusions.
  • history of the stone. Gold and silver jewelry with history are much more valuable. An emerald that, for example, was in the collection of Elizabeth II or another famous person will cost much more.
  • color. The saturation of color and shade depends on the amount of chromium in the emerald: the more there is, the more expensive the product will be.
  • carat content and purity of the mineral. Natural emerald has many inclusions and defects, so it is treated with cedar oil and pigments. A poorly processed stone with inclusions, even weighing several tens of carats, will be cheap.
