Identification of Synthetic or Fake Emeralds from Genuine Emeralds Guidelines

Synthetic Emerald is culturally grown by flux or hydrothermal methods and Synthetic Emeralds resemble Natural Emeralds. Even the facetting/cutting of Synthetic Emeralds are very close to Natural Emeralds. For Online Shoppers it is very difficult to distinguish between Fake & Natural Emeralds. Synthetic or Lab Grown Emeralds wil be deep green free of inclusions. We have provided emerald buying tips for identifying genuine emeralds from fake emeralds for our online shoppers shopping at our emerald rings online jewelry store.

Flux Grown Synthetic Emeralds is made by dissolving nutrients in a molten chemical call flux. These are marketed as Chatham, Crystural, Empress, Gilson, Inamore, Lennix and Seiko.

Hydrothermal Synthetic Emeralds are made by dissolving nutrients at high temperature and pressures in a solution of water and chemicals. These are marketed as Kimberly, Regency, Tairus, and Russian hydrothermal.

Looking through a magnifier is not going to do the trick and some tests and equipments are required to distinguish between Fake & Natural Emeralds.

Gemology Lab Equipment - Sndgems

Synthetic Emerald Hanneman-Hodgkinson Filter Test

Alan Hodgkinson, a Scottish Gemologists discovered a color filters that distinguishes between Fake & Natural Emeralds. Synthetic Emeralds will turn pinkish or reddish when viewed through color filter under sunlight. Natural Emeralds when viewed through the color filter will look greenish. Kimberly and Russian Synthetic Emeralds are not detected when viewed though color filter.

This filter should not be confused with Chelsea Filter or Emerald Filter. Sndgems.com provides free complimentary Synthetic Emerald Hanneman-Hodgkinson Filter with any genuine emerald jewelry puchased from their online jewelry store. This will be a big leap in assuring our online buyers that the emerald that they are getting is truly genuine set in our beautiful emerald jewelry online.

Genuine Emeralds

Refractive Index Test

The speed of light varies in different transparent materials. Each material has a characteristic refractive index, which is the ratio of the speed of light in empty space to the speed of light in the material. Because the speed of light is greatest in empty space, the refractive index of a material is always greater than 1. Gemstones are generally designed so that light entering them from the viewing side (the crown) is internally reflected by facets on its back side (the pavilion) and directed to exit the gem through facets on the crown to the eye of the viewer. Natural Emeralds have slightly higher refractive index than Flux Grown Synthetic Emeralds. Natural Emerald have a refractive index of 1.577 - 1.583 plus minus .017) and birefringence of  0.005 0.009 (GIA Gem Reference Guide) and Flux Grown Synthetic Emeralds have a refractive index of 1.561 to 1.564. Synthetic Hydrothermally Grown Emeralds have a refractive index of 1.577 - 1.583 _plus minus .017) and birefringence of  0.005 0.009 (GIA Gem Reference Guide) and cannot be detected by this test.

Identification of  Emerald Sources - If they're from Columbia, Zambia, Madagascar

Refractive Index of Emerald vary by plus minus .017. Because there is a correlation between place of origin of emerald and refrative index due to impurities found in emeralds from different sources. Refractometer can help in identifying if emerald is from Columbia, Zambia, Madagascar. Sndgems.com offers free complimentary refractometer with purchase of emerald jewelry at their online jewelry store. This will be a big leap in assuring our online buyers that the emerald that they are getting is not only genuine but will know the source of fine genuine emeralds set in our beautiful emerald jewelry online.

Growth Pattern Test

Synthetic Hydrothermally Grown Emeralds have high clarity and are trasparent. If they have inclusion it is difficult to distinguish them from Natural Emeralds. Synthetic Hydrothermally Grown Emeralds have different growth patterns than Natural Emeralds and can be seen through 10X Magnification under different angles but to be really sure use a Microscope. Under different angles growth patterns tend to disappear.

Synthetic or Fake Emeralds

Cross Polarized Test

Alan Hodgkinson, a Scottish Gemologists has discovered that using two polaroid filters and a microscope hydrothermally grown Kimberly Synthetic Emeralds show jagged peak inclusions and Russian Synthetic Emeralds show a pattern like ornamental plate glass door panel. One polaroid filter is placed onto the microscope below the optoc objectives and other fits into the light well. Under different angles inclusions will be seen.

Specific Gravity Test

Specific gravity is the number of times heavier a gemstone of any volume is than an equal volume of water; in other words, it is the ratio of the density of the gemstone to the density of water. For all gemstones listed in this table there is a scientifically determined specific gravity. You can use the specific gravity and a couple simple measurements to estimate the carat weight of a stone.

Gemstone Name Specific Gravity Mohs Hardness Index of Refraction Gemstone Family
Brazilian Emerald 3.03 - 3.25 7.0 - 7.5 Mohs 1.610 - 1.640 Tourmaline
Emerald 2.63 - 2.91 7.5 - 8.0 Mohs 1.560 - 1.605 Beryl

This test measures the relative density of stones by comparing their weight to the weight of an equal volume of water. The specific gravity of Natural Emerald is 2.72 (+0.18 and -.05) and very according to the place of origin. The specific gravity of Synthetic Flux Grown Emeralds is lower than Natural Emeralds like Chatham Flux Grown Synthetic Emeralds is 2.67 and will float when immersed in a heavy liquid with a specific gravity of 2.67 while natural emeralds will sink. Hydrothermally Grown Synthetic Emeralds specific gravity is same as Natural Emeralds and cannot be detected by this test.

High Magnification

Under High Magnification Synthetic Flux Grown Emeralds show inclusions that ressemble fingerprints and veils and inclusion have opaqueness, granular structure that are different from Natural Emeralds.

As a general rule Natural Emeralds have combinations of inclusions like different colored crystals, fluid inclusions, needles while Synthetic Emeralds are more homogneous like flux gron emeralds have flux fingerprints and hydrothermally gron emeralds have chevron growth patterns.

Ultraviolet Fluoroscence

Gems that emit visible light after exposure to short-wave or long-wave ultraviolet radiation, they are said to be luminescent, or more specifically, flourescent. A gem is phosphorescent if the luminescence continues after the UV light source has been removed. This phenomenon of fluorescence and/or phosphorescence is the result of UV radiation absorbed by impurities or structural defects within the crystal structure, resulting in an oscillation of electrons between energy levels, and transmission of visible light.

The fluorescence can be a bold green, orangish-red, or whitish blue, and vary in intensity. Fluorescence may be unpredictable because some gems will have no reaction to the UV light source. Fluorescence testing involves cleaning the stone to be tested and then locating a very dark area for observations. Never look at the UV light source directly, as permanent damage to your eyes can occur. Place the gem on a surface when testing (not between metalllic tweezers or your fingers). Stones that look purplish are inert, with the "purple" color being a reflection of the light source.

Synthetic Flux Grown Emeralds emeralds show a distinctive fluoroscence under ultraviolet light. Natural Emeralds and Synthetic Hydrothermally Grown Emeralds do not show fluoroscence.
