Emeralds have been one of the most loved gemstones for over 4000 years. [1] X Sources of Research Many historians associate emeralds with Queen Cleopatra, the last pharaoh of Egypt. Queen Cleopatra was obsessed with emeralds, so she decorated emeralds on her gown, jewelry, and tiara. Emeralds are 20 times rarer than diamonds, and they are often highly valued.

Observe for impurities. Impurities are any matter (such as air bubbles or tiny crystals) trapped inside a stone during its formation. Nearly 99% of emeralds have impurities that can be seen with the naked eye or with a gemologist’s magnifying glass.
- The presence of impurities makes emeralds a Category 3 gemstone, which means that there is almost always the presence of impurities visible to the naked eye.
- An emerald with a lot of impurities leading to a decrease in transparency or purity is worth less than an emerald with few impurities.
- Be careful with impurities extending to the surface of the jade, as they can cause the gem to crack.

Check the quality of the emerald’s crafting. Emeralds can be difficult to work with because of the presence of impurities that make them prone to cracking during the process. Emeralds are often cut in a rectangular shape (also known as “tiered cut” or “emerald cut”) to help show off the color of the gem. [3] X Research Sources

- Good crafting technique will enhance the color, tone and saturation of an emerald. A good cut will help the gem sparkle and show the desired color, while a bad cut can give the gem a beautiful but opaque color. [5] X Trusted Source Gempogical Institute of America Go to Source

Understand that emeralds come in many different sizes. Like all gemstones, emeralds can range in size from 0.02-0.5 carats (1mm-5mm in diameter) rough stones to 1-5 carats (7mm-12mm in diameter). ) facestone for use as rings or necklaces.
{“smallUrl”:”https://www.wikihow.com/images_en/thumb/2/28/Know-Emerald-Value-Step-4-Version-2.jpg/v4-728px-Know-Emerald-Value- Step-4-Version-2.jpg”,”bigUrl”:”https://www.wikihow.com/images/thumb/2/28/Know-Emerald-Value-Step-4-Version-2.jpg/ v4-728px-Know-Emerald-Value-Step-4-Version-2.jpg”,”smallWidth”:460,”smallHeight”:345,”bigWidth”:728,”bigHeight”:546,”licensing”:” <div class=”mw-parser-output”></div>”}
Don’t equate size with value. It is true that large stones are more valuable than smaller stones. However, the quality of the stones is just as important as their size, large emeralds often have large impurities and this can obviously affect purity. Smaller but better quality stones are usually more valuable than larger but lower quality stones. In addition, the color of the stone also has a significant effect on the value of the stone.

Understand the importance of color. Emeralds come in many colors. Color is one of the most important factors in determining the value of an emerald. The difference in the color of an emerald comes from the difference in the amount of chromium, vanadium, and iron in the environment in which the stone was formed. [6] X Trusted Source Gempogical Institute of America Go to source The color of emeralds can be divided into hue, tone, and saturation categories.
{“smallUrl”:”https://www.wikihow.com/images_en/thumb/e/e6/Know-Emerald-Value-Step-6.jpg/v4-728px-Know-Emerald-Value-Step-6. jpg”,”bigUrl”:”https://www.wikihow.com/images/thumb/e/e6/Know-Emerald-Value-Step-6.jpg/v4-728px-Know-Emerald-Value-Step- 6.jpg”,”smallWidth”:460,”smallHeight”:345,”bigWidth”:728,”bigHeight”:546,”licensing”:”<div class=”mw-parser-output”></div> “}
Determine the color of an emerald. Color is probably what comes to mind when you hear the word “color.” The color of an emerald is its characteristic green color. [7] X Trusted Source Gempogical Institute of America Go to Source
- The color of emeralds can range from bluish green to yellowish green.
- For example, the emeralds of Zambia are characterized by a deep green color, while the emeralds of Brazil and Cpombia are usually pure green. [8] X Trusted Source Gempogical Institute of America Go to Source
{“smallUrl”:”https://www.wikihow.com/images_en/thumb/d/d8/Know-Emerald-Value-Step-7.jpg/v4-728px-Know-Emerald-Value-Step-7. jpg”,”bigUrl”:”https://www.wikihow.com/images/thumb/d/d8/Know-Emerald-Value-Step-7.jpg/v4-728px-Know-Emerald-Value-Step- 7.jpg”,”smallWidth”:460,”smallHeight”:345,”bigWidth”:728,”bigHeight”:546,”licensing”:”<div class=”mw-parser-output”></div> “}
Look at the tone of the emerald. Tone indicates the brightness and darkness of the gem. Emeralds can range in color from light green to very dark green. The relationship between the tone and value of a gem is quite complicated. Dark green emeralds are generally considered to have a higher value, however if the color of the emerald is too dark, its value will be much lower. [9] X Research Source
- Medium to medium-dark green-tone emeralds are among the highest valued gems on the market.
- Pure green or blue-green emeralds are the most in-demand stones, in part because blue-green emeralds are associated with a The prized gem mine in Cpombia is called the Muzo Mine.
- Note that emeralds that are too yellow or too blue may not be considered genuine emeralds and are therefore of much less value.
{“smallUrl”:”https://www.wikihow.com/images_en/thumb/b/b8/Know-Emerald-Value-Step-8.jpg/v4-728px-Know-Emerald-Value-Step-8. jpg”,”bigUrl”:”https://www.wikihow.com/images/thumb/b/b8/Know-Emerald-Value-Step-8.jpg/v4-728px-Know-Emerald-Value-Step- 8.jpg”,”smallWidth”:460,”smallHeight”:345,”bigWidth”:728,”bigHeight”:546,”licensing”:”<div class=”mw-parser-output”></div> “}
Rate the saturation of the emerald. The saturation of the stone is closely related to its purity. Emeralds with high saturation (meaning high purity) have a higher value than those with low saturation.
- Saturation can be tied to both impurities and tones; to some extent including stones of lower purity. Likewise, very dark green emeralds don’t absorb much light, so they appear more opaque than bright blue ones.
Buy Emeralds
{“smallUrl”:”https://www.wikihow.com/images_en/thumb/4/42/Know-Emerald-Value-Step-9.jpg/v4-728px-Know-Emerald-Value-Step-9. jpg”,”bigUrl”:”https://www.wikihow.com/images/thumb/4/42/Know-Emerald-Value-Step-9.jpg/v4-728px-Know-Emerald-Value-Step- 9.jpg”,”smallWidth”:460,”smallHeight”:345,”bigWidth”:728,”bigHeight”:546,”licensing”:”<div class=”mw-parser-output”></div> “}
Choose reputable jewelry stores. Buy gems from a trusted source. Make sure the jewelry store has an established reputation. It is best to choose a jeweler that has a policy that allows returns of products sold due to inaccurate descriptions of purity and quality.
{“smallUrl”:”https://www.wikihow.com/images_en/thumb/f/ff/Know-Emerald-Value-Step-10.jpg/v4-728px-Know-Emerald-Value-Step-10. jpg”,”bigUrl”:”https://www.wikihow.com/images/thumb/f/ff/Know-Emerald-Value-Step-10.jpg/v4-728px-Know-Emerald-Value-Step- 10.jpg”,”smallWidth”:460,”smallHeight”:345,”bigWidth”:728,”bigHeight”:546,”licensing”:”<div class=”mw-parser-output”></div> “}
Valuation of the stone. It is a good idea to let a third party value very high-value gems (or stones that are three carats or more) in weight. It is best to choose reputable testing centers. The list of reputable accreditation centers in Hanoi and Ho Chi Minh City includes:
- Research and Testing Center for Gems and Gold (VGC), 3rd Floor, 91 Dinh Tien Hoang, Hanoi.
- Agribank Gemstone Testing Center, 1st Floor, 91 Dinh Tien Hoang, Hanoi City.
- DOJI LAB, 4th Floor Ruby Plaza, 44 Le Ngoc Han, Hanoi City.
- Institute of Gemology – Vietnam Gemological Association, 10B Tang Bat Ho, Hanoi.
- Institute of Gems, Gold and Vietnamese Jewelry, 2nd Floor, 110 Tue Tinh, Hanoi.
- PNJ’s inspection center is at 52A-52B Nguyen Van Troi, Phu Nhuan, Ho Chi Minh City.
- RGG Gemological Research Center, 02 Nguyen Binh Khiem, District 1, Ho Chi Minh City.
- Inspection Center of SBJ, 278 Cochinchina Uprising, Ward 8, District 3, Ho Chi Minh City.
- Golden Dragon Inspection Co., Ltd – SJC, 422B Nguyen Thi Minh Khai, Ward 5, District 3, Ho Chi Minh City.

Request a gemological certificate from a reputable gemological center such as the Gem and Gold Research and Testing Center (VGC). To properly assess the value of the emerald you intend to purchase, you may request a certificate of inspection from the VGC, which identifies the type, size, workmanship, purity, color and the naturalness of the emerald you purchase.
- This assessment will give you more confidence in the quality and value of your gems, even before third-party inspection.
{“smallUrl”:”https://www.wikihow.com/images_en/thumb/2/2b/Know-Emerald-Value-Step-12.jpg/v4-728px-Know-Emerald-Value-Step-12. jpg”,”bigUrl”:”https://www.wikihow.com/images/thumb/2/2b/Know-Emerald-Value-Step-12.jpg/v4-728px-Know-Emerald-Value-Step- 12.jpg”,”smallWidth”:460,”smallHeight”:345,”bigWidth”:728,”bigHeight”:546,”licensing”:”<div class=”mw-parser-output”></div> “}
Understand prices. Before buying an emerald, you should make sure that you are getting a good quality stone for your money. The VGC’s certificate of assessment will give you a starting point, however, the VGC will not give the stone’s market value. To get a more accurate sense of price, you may want to shop in different jewelers, jotting down the color, style, and quality of each stone you value.
- Remember that the price of a gemstone is extremely subjective, so you don’t have to come up with a specific “recipe” for an exact price for the stone.
{“smallUrl”:”https://www.wikihow.com/images_en/thumb/7/77/Know-Emerald-Value-Step-13.jpg/v4-728px-Know-Emerald-Value-Step-13. jpg”,”bigUrl”:”https://www.wikihow.com/images/thumb/7/77/Know-Emerald-Value-Step-13.jpg/v4-728px-Know-Emerald-Value-Step- 13.jpg”,”smallWidth”:460,”smallHeight”:345,”bigWidth”:728,”bigHeight”:546,”licensing”:”<div class=”mw-parser-output”></div> “}
Understand the oil coating process. Emeralds are often treated with oil to increase the clarity of the stone. Oiling is a common treatment and is seen as a minimal treatment to enhance the beauty of the gem. [10] X Trusted Source Gempogical Institute of America Go to Source
- Ask if the emerald has undergone minor, medium, or large treatments. Minor treatments, such as oiling, are quite common, while major treatments such as coating with turpentine or staining the stone will alter the appearance of the stone and mask its true color.
Advice
- Be sure to find out if the emerald is a natural stone or a lab-made imitation. The stones are so pure, with a brilliant blue color and almost no impurities that are probably “too perfect”, which indicates that it is a high-quality imitation from a laboratory.
- Let an independent person who has no connection to the person you purchased the stone from to inspect your gem before or shortly after you purchase the stone. If the stone is not authentic or was sold to you with inaccurate information about quality, return to the jeweler with written inspection for a refund or exchange for another stone.
Warning
- Always purchase emeralds from a reputable jeweler with a return policy for incorrect or untrue information.
