The Gift from Venus

Since time immemorial, the emerald variety of beryl has been adored for its elegant green colour, which symbolizes nature’s gift of the spring season for mankind. Ancient fables abound about Goddess Venus being lavished with gifts of emerald.
Back in 3500 BC, the ancient Egyptians discovered emeralds in the desert southwest of Cairo, a gem that became extensively worn. In 1600 AD, huge emerald deposits emerged from the ground in Muzo of Colombia, following a torrential flood. Later, the
Spanish immigrants stunned the entire Europe and even the world when they took this enormous batch of gemstones back to their home country. Emeralds can be found in many Royal jewellery collections. They include those from the royal family of the bygone Iranian dynasty and the regnant Queen of England. Even the gold-woven quilt of Empress Dowager Cixi of Qing-dynasty in China had been embroidered with two emerald pieces that weighed over 80 carats.
Apart from Colombia, emerald deposits have also been found successively in Russia, Brazil, Zimbabwe and Zambia. However, Colombian emeralds remain unrivalled in quality and prices. The mines in Egypt where emeralds were first extracted are now depleted.
Emeralds are more difficult to mine than other gemstones and more resources are wasted in the process. As a result, they are sold at extremely high prices.
Natural emeralds are more or less covered with cracks and irregularly-shaped crystalline.
The cracks are often filled with oil to render these gemstones in perfection. Such a practice has been widely accepted, adopted and endorsed in the industry, given that oil injection does not compromise the gemstone’s integrity or its crystalline combinations. Natural, nonenhanced emeralds with fewer inclusions are extremely rare and highly treasured by jewellery connoisseurs and investors.
