A Short History of Emeralds
According to the Gemological Institute of America (GIA), the first known emerald mines were in Egypt, dating from at least 330 BC into the 1700s. Cleopatra was known to have a passion for emeralds and used it in her royal adornments.
Some of the most famous emeralds were looted by Spanish conquistadors in South America when they invaded the New World in the 16th century. It includes the Mogul Mughal Emerald, a 217.80ct carved emerald sold at Christie’s for $2.2 million in 2001. It now resides in the Museum of Islamic Art, Doha, Qatar.
When the Spanish invaded, the Incas had already been using emeralds in their jewelry and religious ceremonies for hundreds of years. It wasn’t long before the trade in emeralds caught the attention of European and Asian royalty. And the popularity of emeralds only increased over the centuries that followed.
Emeralds are often used in engagement rings as an alternative to a traditional diamond.

The 4Cs of Emeralds
All gemstones are evaluated based on the 4Cs – color, clarity, cut, and carat (weight).
An emerald gets its color from trace amounts of chromium, but vanadium can also play a role.
Color plays a critical role in emeralds and can be broken down into three components, namely Hue, Tone, and Saturation.
Hue – Emeralds, by definition, can only be green in color. Slight color variations, such as bluish green and yellowish green are acceptable. But, if it’s too yellow, it’s no longer an emerald but a green beryl instead.
Tone – An emerald must have a medium-light tone. If not, it’s classified as a green beryl.
Saturation – Refers to color purity.
Emeralds nearly always have fracture-filled inclusions or imperfections. In addition, they typically have crystalline minerals inside them. And a combination of liquid, solid, and gas inclusions are common.
The cut of an emerald can, to some extent, determine its clarity. But gem cutters often don’t have much to work with, especially with stones that have a high number of inclusions.
Note: Colored gem cuts are seldom perfectly symmetrical. The cut is typically adjusted to maximize the weight of the gemstone.
Carat weight plays an important role in determining the price of an emerald. As a rule of thumb, all else being equal, the price doubles with every carat increase. For example, if a one-carat gem is worth $1,000, a two-carat one will be worth $2,000, and a three-carat one $4,000.
Note that although clarity and cut have an impact on the price as well, the primary factor that determines an emerald’s value is its color.
How to Clean Emeralds
The safest way to clean an emerald is gently scrubbing it in warm, soapy water.
Cleaning emeralds ultrasonically or with hot steam is risky as most emeralds are fracture-filled.
