Hooker Emerald Brooch
The Hooker Emerald Brooch is an emerald brooch designed by Tiffany & Co.. As of 2010, the brooch is on display in the Janet Annenberg Hooker Hall of Geology, Gems, and Minerals at the Smithsonian Institution's National Museum of Natural History in Washington D.C., United States.
==Description==
The Hooker Emerald Brooch consists of an open-ended circular band of platinum. The two ends of the band curl outwards into scrolls, and are connected by a round brilliant cut diamond. 108 other round brilliant cut diamonds are studded along the band. Spokes cross the band, converging to form the setting for the Hooker Emerald at the centre of the brooch. Ten pairs of baguette-cut diamonds project between the spokes from behind the emerald towards the platinum band. The Hooker Emerald itself weighs 75.47 carats.〔"(Catalog Number: G7719 )", ''GeoGallery'', Smithsonian Institution (2008). Retrieved March 31, 2010.〕 It measures 27 mm to a side and is remarkably free of inclusions for its size.〔Morgan, Diane (2007); ''From Satan's crown to the holy grail: emeralds in myth, magic, and history'', Praeger Publishers Inc., ISBN 978-0-275-99123-4〕 The gem's cut gives the appearance of a series of concentric squares within the gemstone (known as a beveled square emerald cut.) In total, the brooch contains approximately 13 carats of diamonds.〔
