Mogul Emerald Necklace

A Columbian discovery, this emerald made its way to India, where it was carved with a floral pattern reminiscent of the Mughal style. One belief is that it was carved instead of faceted because of the natural inclusions in the beryl which make the gem brittle in nature and susceptible to breakage. It is also possible that carving the stone instead of cutting facets was simply a conscious stylistic choice for that era of trends in jewellery making. The emerald is in the form of a pendant encircled by round diamonds and the necklace, in turn, is made up of two rows of diamonds; in all, the diamonds make up 50 carats worth. This emerald necklace is now a part of the National Gem Collection in the Smithsonian.
Mogul Mughal Emerald

This is a rectangular tablet, dark green in colour also believed to be mined in Columbia. It is arguably one of the largest emeralds in the world, table-cut and weighing about 217.80 carats. It bears the carving of Arabic inscription on one side with a date marked as 1107 A.H. and a floral motif on the other side consisting of a rosette surrounded by poppies. Each of the sides has a hole drilled into it, possibly for attachments. Christie’s, New York auctioned off the emerald to an anonymous buyer for 2.2 million dollars sometime around or after 2001. The gemstone is reported to be in the Museum of Islamic Art, Qatar as of today.
Guinness Emerald Crystal

This emerald used to be one of the largest natural emerald mined from Coscuez; one of the three significant mines in Columbia, the other two being Muzo and Chivor. 1,759 carats in weight, this emerald is bright green in colour and is an elongated crystal with twelve sides (dihexagonal). The emerald is somewhat translucent and there are fissures towards the bottom of it that are quite clearly visible to the naked eye (as is the case for most emeralds where visibility is concerned). It is currently in the care and possession of the Banco Nacionale de la Republica in BogotÃ, Colombia.
Mackay Emerald Necklace

This spectacular gem made its way from the mines of Muzo to Cartier’s, who set it in a necklace. The emerald weighs 167.97 carats and it serves as a pendant surrounded by emeralds and round brilliant and step cut diamonds and is set in platinum. It was a wedding present to Anna Case, a prima donna of the New York Metropolitan Opera from her husband Clarence Mackay; which is where it got its name. It was donated by Anna Case Mackay to be a part of the National Gem Collection in 1984 and is currently on display and in the possession of the Smithsonian Institute.
