Petersen Tanzanite Brooch
|Catalog Number||NMNH G10195-00|
Gift of Donald E. and Jo A. Petersen in 2002.
The gem variety of zoisite known as tanzanite was first discovered in 1967 in Tanzania. Tanzanite is a strongly pleochroic gem, appearing intense blue, violet, or red depending on the direction from which the crystal is viewed and the orientation in which a gem is cut. This magnificent pair of matched tanzanites weigh approximately 30 carats. These modified triangular cut gems exhibit beautifully the highly-prized intense sapphire-blue color with modifying highlights of violet this is sought after. The floral platinum brooch, designed by Harry Winston, Inc. in 1991, has approximately 24 carats of marquise, pear and baguette cut diamonds. The tanzanite “flowers” can be detached and worn as earrings.
