On April 25th, the nearly 110-year-old 34.4ct Colombian micro-oil emerald Monogram Ring was sold at Sotheby’s New York auction for $996,500. The named Stotesbury Emerald was first inlaid with a 94.8ct pear-shaped diamond “Star of the East.”
It was purchased in 1912 by American banker Edward Stotesbury and presented to his wife. American jeweler Harry Winston purchased the emerald in 1943 and redesigned it to the current platinum ring, which is still in use today. This emerald has changed hands and is loved by celebrities. It can be said to be a microcosm of many high-quality emeralds.
Among the celebrities in the world, the most famous of the emeralds is the late American legendary star, Elizabeth Taylor. This inlaid 16 Colombian Emerald Jewelry Necklace with a total weight of 60.5ct is the first piece of jewelry that gave her by Taylor’s sixth husband, Chardon Burton, which is a piece of jewelry of the most worn by Taylor when attending important occasions.
In addition to Elizabeth Taylor, various stars are a preference for emeralds, as evidenced by the re-emergence of emerald couples jewelry(Couple’s Breakable Heart Love Necklace) in various important events. Do you really know her like an emerald called “big three” in the colored gem world with rubies, sapphires?
Emeralds are produced in many places in Colombia, Brazil, Zambia, Russia, India, Zimbabwe, Madagascar, etc., but the gem-quality emeralds currently on the market are mainly from Colombia, Zambia, and Brazil. Among the three producing areas, Colombia is recognized as the highest quality emerald producing area in the world.
Among them, the Muzo area is synonymous with the top color of emerald in the jewelry market because of the emerald color that often appears in the top color. Compared to Colombia with a long history of emeralds, Zambia can be said to be a newcomer in the emerald production area. Currently, the country’s emerald is mainly mined by the famous Gemfields company, and now it can be regarded as the second largest emerald producing countries in the world.
As the origin of emeralds in Brazil, although not as good as Colombia and Zambia, there is still no shortage of high-quality emeralds. Although the emerald’s origin affects his price to a certain extent, each producing area will produce its high-quality emerald, and the final quality evaluation will return to the quality of the emerald itself.
Among the factors that affect the value of emeralds, color is its core criterion. The color of the “top emerald” is a comprehensive performance, not just a simple color. The color of the high-quality emerald is a little blue or no other color, high color saturation, bright green, and this requires uniform color distribution, no visible color bands, and high transparency.
Therefore, yellowish color, too much blue color, low color saturation, low color brightness, uneven color distribution, visible color bands, and low transparency will reduce the value of the emerald. Emeralds with bright colors and bright blue. When an emerald reaches the top color described above, some appraisal agencies will describe her as ” Muzo color”. For example, the Swiss color identification agency GRS will meet the agency required the color to reach the Vivid Green emerald color, with the note “Muzo Green“. Emeralds that reach the Muzo color are usually expensive.
In addition to color, clarity is also one of the factors that have a greater impact on emerald value, usually the cleaner the emerald, the higher the price. Emeralds often contain microscopic inclusions, and even the top emeralds on the auction stage contain macroscopic inclusions.
So, when you come across a whole clean, innocent emerald, it’s not that you are lucky, and you’ve come across a synthetic emerald. In the same size, the price of an emerald depends mainly on his color. When choosing an emerald, the first thing to consider is its color. If you pursue excessive clarity, it will only miss the high-quality emerald.
Emerald’s “micro-shaping” like many gems. Emerald also has his own optimized treatment. Commonly, there is oil immersion optimization, filling, dyeing and laminating. Filling, dyeing and laminating are all areas of processing and are difficult for many consumers to accept. So we mainly talk about emerald “micro-shaping”: oil-immersed optimization.
Top Emeralds without any cracks are very rare. So people have studied the emerald oil immersion optimization to improve its clarity. Infused into the emerald is usually an oil that is similar in refractive index to the emerald. Because the refractive indices of the two are similar, the extent to which light changes direction as it passes is minimized, which masks these cracks to the maximum extent visually.
In addition to improving transparency, emeralds are more brittle and easily damaged during processing. The oil immersion can protect the emeralds with more cracks and prevent fragmentation.
