The Crown of Muzo
Emerald is a green mineral beryl, coloured by trace amounts of chromium or vanadium. The varying presence of these elements gives
emerald its range of colour which until now, no gemologist has ever accurately described its colour - green with a touch of yellow and
seemingly a bluish tint, making emerald an arresting sight to behold.
Cleopatra, the queen of ancient Egypt, was known to have a passion for emerald. One millennium later, the gemstone captured the heart
of actress Elizabeth Taylor, who played the bewitching queen on the silver screen. Taylor recalled the scene she visited the Bulgari’s shop in
Rome, “a green glitter emerged and all we could do is to hold our breaths. Oh my God! I’ve got to have the emerald!”
Emerald is formed under extremely complex geological conditions. Though exceedingly beautiful, they are brittle and contain numerous
inclusions that are described by gemologists as an internal “jardin,” or garden. Due to this unique characteristic, the main focus of emerald
enhancement is to deal with their cracks. One of the widely accepted enhancements is oil treatment (colourless oil). Filling them with oil
makes their fractures less visible and helps protect the gem crystals. Almost all emeralds in general are subject to oil enhancement, except
for a precious few that are so naturally perfect they are spared this treatment.
Colombia is a famous producer of emeralds in the world. Backed with a unique geographical environment, it provides excellent growing
conditions for emeralds. The country’s Muzo mining region yields emeralds of the finest quality, so beautiful that collectors find it hard to
resist them. Amongst the limited mines within Colombian borders, Muzo mine produces the most saturated pure green to slightly bluishgreen
emeralds, creating the lushest allure of green gemstones that make collectors scramble for. Muzo emeralds are called “oil drops”
by the locals. Along with the increasing demand for emeralds coupled with markedly curtailed outputs from the Colombian mines over
the years, Muzo emeralds are close to depletion. Colombian Muzo emeralds above five carats are rare, those in excess of ten carats are
exceptionally rare.
To be offered in the auction is a 29.16-carat untreated Colombian Muzo emerald “Crown of Muzo”, with prestigious origin and impressive
quality, this gemstone is truly an arresting beauty.
