The name “emerald” comes from the ancient Greek word for green, “smaragdus.” Emerald was said to be the gemstone of the goddess Venus (the goddess of love and beauty) in ancient Greece and Rome, and was considered to aid in fertility.

The first known emerald mines were in Egypt, not far from the Red Sea. It is believed that these mines were worked as early as 3500 BC. For the Egyptians, emeralds were held in high regard by the Incas and believed to be a source of eternal life. The Incas had already been using emeralds in their jewelry and religious ceremonies for 500 years.

Emeralds were also considered to be a gift from Thoth, the ancient god of wisdom. Egypt’s female seductive monarch, Cleopatra, was famous for wearing emerald jewelry. Ancient Egyptians believed emeralds could be used to treat eye diseases and that the green color represented fertility and rebirth. Egyptians often buried their dead with emeralds to symbolize eternal youth and when visiting dignitaries left Egypt, Cleopatra presented them with a likeness of herself carved into large emeralds.

He also stated “An emerald hung from the neck or worn in a ring will prevent the falling sickness.”

The Roman magician Damigeron stated that an emerald “influences every kind of business, and if you remain chaste while you wear it, it adds substance to both the body and the speech.”

GIA gives a clear guide as to how to buy emeralds.

Chromium, vanadium, and iron are the trace elements that cause emerald’s color. The amount each of these elements are present or absent in the stone determines the exact color of an emerald crystal.

When shopping for emeralds, professionals generally agree that emeralds are most of all about color. Subtle variations make significant differences in value. The most desirable emeralds are highly transparent and colored bluish green to pure green, “with vivid color saturation and tone that’s not too dark,” according to GIA. The color should be “evenly distributed, with no eye-visible color zoning.”

Sometimes the appearance of an emerald, meaning its color, is associated with the location of where it was mined. GIA says that emeralds mined in Colombia are said to have a warmer and more intense pure green color, while Zambian emeralds are said to have a cooler, more bluish green color.

Eye-clean emeralds, where there are no inclusions visible to the unaided eye, are very valuable because they’re so rare. Emeralds typically contain inclusions and because of that most traders and some consumers understand and accept the presence of inclusions. Something to remember, though, is that when the inclusions have a negative effect on transparency and clarity, they also dramatically reduce the value of the emerald.

In terms of clarity, GIA says “expect to see inclusions that dealers like to call an internal ‘jardin,’ or garden. When looking at carat, because an emerald’s density is lower, a one-carat emerald will appear larger in size than a one-carat diamond.” According to GIA, the most popular and common cut for the stone is the emerald shape (which is rectangular) because of the original shape of the crystals. Stones that are cut well maximize the beauty of its green color (making it brighter and livelier) while minimizing the impact of fissures. Emeralds are also difficult to cut but Colombian rough emeralds is especially hard because the distribution of “coloring agents” during formation, GIA says.

On May 16, the auction house Christie’s in Geneva offered a Tiffany & Co. diamond-and-emerald necklace made between 1880 and 1890. The necklace has old-cut diamonds, upside-down fleur-de-lis motifs, unusual circular-cut emeralds from Colombia, and its central largest emerald has not been treated at all. Christie’s cited a specialist saying that the green gemstones may have come from the famous collection of Queen Isabella II of Spain. In 1878, she auctioned some of her emeralds in Paris and at the time Tiffany & Co. imported royal and imperial gems to America where wealthy families, such as the Vanderbilts, were eager to get a hold of these pieces.

To clean your emerald, use room temperature running water and a soft toothbrush with mild soap. Brush repeatedly on the underside of the emerald to remove dirt and grease that may have accumulated over time.
