Geological Origins of Colombian Emeralds
Colombian emeralds are renowned worldwide for their exceptional quality and deep green color. The emerald mines in Colombia are among the most profitable in the world. Historical geological records indicate that emeralds were mined from this region even before the Spanish conquistadors arrived in Colombia in the 16th century.
For over half a century, the Incas used emeralds in jewelry and religious ceremonies. Colombian emeralds, with their unique deep hues, allure, and high prices, stand out in necklaces, rings, earrings, and bracelets.
The Legendary Colombian Emerald Mines
Colombia has two main mining areas: Muzo and Chivor. The Muzo mine is also known as the “World Capital of Emeralds.” This mine is famous for producing emeralds with the deepest, richest colors. The Chivor mining area yields emeralds with more bluish-green tones. Both of these mines are still operational today, producing 70-90% of the emeralds in the global market.
The vibrant green color of Colombian emeralds comes from the presence of trace elements such as chromium and vanadium. The most desirable emeralds from these mines will have the highest clarity and the least visible inclusions.
The Secrets of Colombian Emeralds
Colombian emeralds have long been surrounded by charm and mystery. In many cultures, emeralds are considered symbols of fertility and rebirth. Emeralds are also believed to possess mystical powers. This mystical power stems from ancient Incan stories, which claim that emeralds can bring good luck, enhance intuition, promote healing, and balance.
Emeralds were once thought to cure diseases such as cholera and malaria. Today, emeralds are the birthstone for May and the traditional gift for 55th wedding anniversaries.
Purchasing Natural Colombian Emeralds
Natural, unheated Colombian emeralds are the most sought-after in the luxury market. When searching for emerald jewelry, it’s crucial to focus on the best cut, clarity, color, and carat weight. It’s also important to look for “No Oil Colombian Emeralds” or “No Treatment Colombian Emeralds.” Oiling is a treatment used to improve the clarity of emeralds by filling fissures with oil, making inclusions less noticeable.
While this process can enhance the gemstone’s appearance, it deprives the stone of its natural beauty and diminishes its value. No Oil Colombian Emeralds represent the pinnacle of natural beauty in emerald gemstones. When purchasing emeralds, always look for GIA or EGL certification proving the gemstone is in its natural state.
The 4Cs of Colombian Emeralds
When buying emeralds, it’s essential to consider the four Cs: Cut, Clarity, Color, and Carat weight to ensure you’re selecting a high-quality gemstone. Emeralds belong to the beryl family. In terms of emerald atomic structure, high levels of chromium, coupled with low levels of iron, can lead to crystal stress fractures, reducing the clarity of vivid green emeralds.
Emeralds are considered Type III gemstones because they always contain some inclusions. Inclusions in emeralds are known as “Jardin.” Jardin means garden in French, and gemologists consider these minute flaws similar to a garden’s intricate patterns. When evaluating an emerald’s clarity, we recommend looking for an emerald with a clarity grade of SI1 or above.
Regarding emerald color, the iconic green of emeralds can range from bluish-green to true green to yellowish-green. Colombian emeralds owe their unparalleled deep green color primarily to the element chromium, the same element that gives rubies their unique red hue. While this unique chromophore is positive in terms of color, it compromises clarity. Colombian emeralds are the most popular because they have a vibrant blue-green color.
The most popular cut is the emerald cut. This is because emeralds are known for their “brittle” nature, making them susceptible to fractures. By cutting emerald gemstones in the emerald cut, it maximizes clarity, enhances color, and maintains the stone’s structural integrity.
As for carats, it depends on the type of creation you’re pursuing. For emerald rings, we recommend starting with at least 3 carats. Finding natural Colombian emeralds with vibrant blue-green hues and few inclusions is extremely rare. Colombian emerald jewelry prices range from $10,000 to $100,000, depending on the emerald’s size and quality, setting, and origin.
Buying Colombian Emerald Jewelry
Today, Colombian emeralds are among the most expensive gemstones on the market. Over the past 15 years, global auction prices for natural emeralds have been rising at a rate of 10% annually.
In December 2022, Sotheby’s auctioned a 400-year-old Colombian emerald ring that was salvaged from a shipwreck in 1985. This 5.27-carat octagonal step-cut emerald set in gold was initially estimated at $50,000-$70,000. The ring exceeded its estimate, selling for a record-breaking $1.2 million.
