Magnificent Emeralds


Tiffany & Co. announced that the House has acquired an extraordinary gemstone: an emerald of over 10 carats. Sourced directly from Muzo Emerald Colombia, where the world’s finest emeralds are unearthed, the exceedingly rare ‘Tiffany Muzo Emerald’ is named after its source, the renowned Muzo mines, located 60 miles northwest of Bogotá.

“As the world’s authority on rare gems, we are thrilled to announce our recent acquisition of the Tiffany Muzo Emerald,” said Victoria Wirth Reynolds, Chief Gemologist, Tiffany & Co. “This remarkable stone, weighing over 10 carats, is a continuation of Tiffany’s longstanding heritage of acquiring the most coveted gemstones that Mother Nature has to offer.”

The Tiffany Muzo Emerald

Weighing over 10 carats, this rectangular square cut emerald was extracted from the historical Puerto Arturo shaft in December 2019. This emerald is exceedingly rare due to its exceptionally high clarity, which provides a superior degree of transparency, which highlights its exceptional color.

This emerald has absolutely no fissures and is virtually inclusion free, displaying only a few inclusions found by microscopic examination, which are consistent of those found in Colombian emeralds from the Muzo mine. Furthermore, this historic emerald showcases the perfectly saturated green color that Muzo emeralds are so highly coveted for.

This is a 75.47 carat, square, inclusion-free Colombian emerald that was originally the property of Abdul Hamid II, Sultan of the Ottoman Empire. The emerald was used by the sultan to decorate a belt buckle until it was purchased by Tiffany & Co in 1911 and was made into a brooch. The brooch has 109 round diamonds and twenty baguettes, the combined weight of the diamonds are 13 carats. Mrs Janet Annenberg Hooker (sister of Walter Annenberg) purchased the emerald brooch from Tiffany in 1955 and donated it to the Smithsonian Institute in 1977.

Neither the origin nor the name of this necklace can be substantiated. We know that parts of the original necklace are over three hundred years old, and some believe its gemstones to have once belonged to the Spanish royal family. Is 374 diamonds must have come from India as India was the only diamond source at that time. There are 15 emeralds, the largest of which is 45 carats, all of which came from Colombia. According to experts the necklace that exists today was probably created in the twentieth century, judging from its style. The Maharaja of Idore owned the necklace until 1948 when it was purchased by Harry Winston. The necklace became part of the National Gem Collection when it was donated to the Smithsonian Institute by Cora Hubbard Williams in 1972.
