Emerald Information

Today, in this article, I am going to answer some questions about Emerald.

  •       How to check the quality of a true Emerald?
  •       What would be the price of the Emerald?
  •       How to buy an Emerald? Are they treated?
  •       How to take care of your precious Emerald?
  •       In the last segment, we have listed few pictures of emeralds from our stock.

Yeah, I know, these are the common questions that come to a customer’s mind while going to buy a precious gemstone “Emerald”.

Please allow me to tell you about the judgment of the quality of a true Emerald. A natural and genuine Emerald is deep green in color. Bluish-green to pure green are also acceptable. The stones with lighter hue are not Emeralds, but green beryl. A true emerald will be as darker as a glass Coke bottle. Emeralds typically have some inclusions, which are tolerable.


Now the question is how does inclusion occur? Inclusion occurs when an unfamiliar material is inside it. These inclusions may be solid, liquid, or gas-filled. An emerald with inclusions and darker in color is more valuable than one with a dull color. If you want to see the flaws, which are not visible with naked eyes, then use a magnifying glass. It is possible that a high-quality Emerald is a bit cloudy, but it should possess noteworthy transparency.

Get all the details about the Emerald treatment from the jeweler or gemstone dealer before buying it. Emeralds are susceptible and can react pessimistically if they have been treated improperly; if the pores that naturally occur in an emerald are sealed with enrichment materials, it may dull the stone’s appearance.

There are some trace elements like chromium, vanadium, and iron which are a cause of color in Emerald. The proper balance of these elements determines the exact color of an Emerald crystal. This is the reason that different mining location of Emerald is the cause of its different appearance. It is said that the Colombian Emeralds have a warmer and deeper pure green color; Zambian Emeralds have a sophisticated, more bluish-green color.

There are four following characteristics of Emerald crystals, which make them difficult to cut:

  1. Almost all Emeralds have noteworthy cavities, also known as fissures in the trade.
  2. Because of these inherent fractures, Emeralds are more fragile than Ruby or Sapphire. This makes Emeralds sensitive to damage while cutting, polishing, and setting. You should also wear it very carefully for daily use.
  3. Because the color is very important in establishing Emerald’s price, the cut must maximize the effect of hue, tone, and saturation.
  4. The bluish-green to yellowish-green dichroism of many Emerald crystals persuades the gem cutter to familiarize the table so it’s making a corner to the length of the crystal. That way, the more perceptible color in the cut gem is the bluish-green, which so many emerald lovers prize.

The Emerald size ranges from 1 mm to hundreds of carats. The price of the Emerald increased dramatically as the size increases. The beautiful Green jewel, Emerald, has 7.5 to 8 hardness on the Mohs scale of hardness, which is fair to good robustness, but this does not mean that they can afford a harsh cleaning. This is the reason, but that Emerald requires more care in wearing than Ruby or Sapphire.

The hardness of Gems and minerals is measured on the Mohs scale. Hardness is measured in numbers that are based on the moderate ease or difficulty with which one mineral can be scratched by another. But the Mohs scale is illusory.

As you can see in the image below, a diamond has a hardness of 10, which is only one number away, but many times harder than Ruby, Sapphire, or Emerald.

Here are few points to take care of an Emerald to keep it long-lasting:

  1.  It should not be exposed to high heat, it can damage emeralds by lengthening existing cavities. 
  2. You should follow a good rule of thumb for it. The rule is if you cannot put your hand in the hot cleaning solution, then you should not place your valuable Emerald in it.
    (Some guesstimates state that more than 90% of emeralds in the market are fracture-filled. It is unsafe to clean these fracture-filled Emeralds ultrasonically or with steam. Ultrasonic vibrations can deteriorate already-fractured stones, and hot steam can cause oil or unhardened resin to sweat out of cavities.)
  3. Light and chemicals can cause the oils, resins, and polymers used to fill surface-reaching cavities to amend in appearance or corrode.
  4. The safest way to clean an Emerald is to use warm soapy water coupled with gentle scrubbing is the safest way to clean emeralds. 
  5.  You can also use a mild detergent solution with a very soft scrubbing brush. Emeralds are classically oil-treated to perk up the lucidity and gleam.

The cleaning solution of Emerald should not contain petroleum distillates or any other organic solvent, whether the solution is a verified “jewelry cleaner”. Organic solvents are not attuned with the oil treatment of Emeralds.

To clean your precious Green Jewel, soak it in a dishwashing detergent solution for approx 10-15 minutes and then mounted it with a soft brush. The Emerald should then be rinsed with warm water and patted dry. You should not leave your Emerald engrossed in the cleaning or rinse solution any longer than is necessary.

The following image will show you the difference in Natural Emerald and the Emerald after treatment:

According to the quality, the price range of Emerald starts from $ 30.00 per carat to $ 9800.00 per carat. The fine quality of Emerald has, the high is the price.

Most of the Natural Emeralds have not only copious internal inclusions and fractures but also petite surface-breaking cavities or cracks. The reason, why most the Emeralds are treated, is to improve their clarity.

Oiling with cedar oil is the traditional treatment for Emeralds. Cedar oil is naturally extracted from cedar trees. It is colorless, glutinous, and very sticky. It is not easy for Cedar oil to penetrate the microscopic cracks in Emerald because it is very viscous and sticky. To do this requires some heat and pressure.

Traditional oiling is stable but it is not enduring. In the long run, an oiled emerald will require re-oiling to keep it’s best looking. This is the reason that there have been innumerable attempts to set up post filters, which will be more eternal. These involve natural and simulated resins (such as Opticon), and polymers and pre-polymers. You can see the difference between Natural Emerald and Treated Emerald in the image below:


Navneet Gems and Minerals has been a manufacturer of wholesale synthetic gems or lab-created gems and supplying them to the major important jewelry companies around the world. So, if you are going to buy an Emerald, you should keep all these things in your mind. The following video will help you to understand the cutting of the Emeralds.

Zambian Emeralds are one of the best Natural Emeralds in the market. They are high in quality and high in price as well. 2020 was a big year for getting back to nature, the rural and in 2021, we continue to be inspired by nature and a big color trend is green. Teal Greens, Olive greens, emerald greens, sage greens, they are everywhere right now and it’s such an easy, versatile shade to pair with absolutely anything. 

You know what is interesting about Emeralds, which is the birthstone of the month of May; they are one of the four precious gemstones in the world, which can be costly, depending on the quality, more than a diamond sometimes. Emeralds are mined in more than 30 countries which include Brazil, Afghanistan, Bulgaria, Canada, Egypt, France, India, Kazakhstan, Mozambique, Nigeria, Pakistan, Somalia, Spain, Tanzania, Zambia, Zimbabwe, United States, Switzerland, South Africa, Russia, Norway, Namibia, Madagascar, Italy, Germany, Ethiopia, China, Cambodia, and Australia.
