Green With Envy: Why Emeralds Make Some Of Us Mad With Desire

Last month some of the world’s wealthiest jewelry collectors gathered at the Four Seasons Hotel in Geneva for an auction of rare gems. They had green in their eyes. “Here we have showing on the left the stunning ‘Patino’ emerald and diamond Cartier necklace,” the Christie’s auctioneer said. “We shall start the bidding at five million Swiss francs.”

Attendees raised their hands – and the stakes. When the auctioneer slammed down his gavel, the winning bidder had committed to paying 9,125,000 Swiss francs, or roughly $10 million. That made it the second highest price ever paid at auction for an emerald and diamond necklace.

It was just the most recent in a series of auctions where emeralds have reached many times their estimate.

The price for high-quality emeralds has increased by a factor of 10 since 2009, and the price of Colombian emeralds is set to increase by at least 25% this year alone.

Gemfields, the world’s largest producer of the green stones, has seen the price of its emeralds soar sixfold in the past four years. Meanwhile the International Diamond Manufacturers Association has warned that, following current growth rates, emeralds could slash the diamond market share by 20% in the next two decades.

Given the growing popularity of emeralds, maybe diamonds aren’t forever.

Why is this happening? The lofty prices are simply further proof of our enduring fascination with these alluring, mysteriously enigmatic stones. From Cleopatra to Catherine the Great to the Maharajahs of India, the world’s most powerful men and women have always coveted them — and inspired the masses to do the same.

The value of emeralds stems, in part, from their scarcity: they are over 20 times rarer than diamonds — a consequence of the extraordinary conditions required to create them. Beginning 500 million years ago, magma and hydrothermal fluids—rich in aluminum, beryllium, silicon and vanadium—cooled amid a delicate balance of heat and pressure, forming the precious gems.

Today most emeralds are mined in Colombia, Brazil and Zambia, and then sent to Jaipur, the emerald capital of the world, where artisans cut and polish them. Long before you encounter an emerald, it has been on a long and magnificent journey.

Much of the wonder and awe relates to the gem’s color. In normal lighting conditions, the human eye responds most strongly to yellowish-green light. Natural light, including sunlight and candlelight, also happens to be at its most intense at this point of the visible spectrum.

This coincidence of physics and human physiology explains why emeralds can appear so wonderfully, almost supernaturally vivid, as when you look at a field of lush green grass on a sunny day.

Historically jewelers have added to the emerald’s luster by setting it in yellow gold, which was thought the purest form of metal — and the closest thing to Godliness. People are subconsciously drawn to this warmth. Owing to chromium in its chemical make-up, the emerald doesn’t just reflect light, but also gives it off. It’s no exaggeration to describe it as radiant.

Queens and Maharajahs

Across cultures and across time, ancient peoples came to view the stone as having unusual powers. The Romans believed it could revitalize the soul of whoever wore it, and Pliny the Elder wrote that staring into the stone could soothe the weary eyes of jewel-cutters.

In several Middle Eastern cultures people wore emeralds thinking they would discourage snakes from biting them. This didn’t work for Cleopatra. But these perceived powers raised the profile of the gem, nourishing a desire that continues today.

The global emerald trade picked up during the 16th century after the Spanish Conquistadors captured the Inca Empire.
They exported Colombian emeralds to Europe and the Philippines. Soon even more people praised the emerald for its purported medicinal qualities, perhaps spurred on by the legend and myth surrounding the gem.

In 1609 Anselmus de Boodt, a Belgian mineralogist and physician, suggested that the green stones could cure dysentery, fever, panic attacks and epilepsy. One wonders if he had shares in an emerald mine.

Emeralds from Colombia also made their way to India. Mughal Emperors carved verses of the Koran into the gemstones, creating a strong link between emeralds and divinity. Shah Jahan, the ruler who built the Taj Mahal, loved emeralds so much that he had them inscribed with sacred text and wore them as talismans. Some of these sacred stones, called Mogul emeralds, can still be seen in museums and collections today.
