Demantoid means “diamond like,” and the gem displays an adamantine luster with amazing brilliance and dispersion.  Gems larger than a few carats are extremely rare.  Dematoid gems are usually high in clarity but may contain characteristic inclusions of byssolite, needle-like radiating inclusions referred to as “horsetails.” Today, because of limited supplies, demantoid maintains its status as a rare and valuable gem.  Demantoid has been found in Italy and Iran, and more recently Namibia (1996). However, the Russian material continues to be the standard by which the gem is judged. This beautiful cushion-cut demantoid, found in Russia in the late 1990s, exhibits the vivid intense emerald-green color that is very rare and highly prized.  At 11.24 carats it is a major upgrade for the National Gem Collection.  It is a world-class gemstone and one of the largest and finest faceted demantoids known.  - See more at: http://geogallery.si.edu/index.php/en/10266183/demantoid#sthash.30mRmn95.dpuf

This platinum bracelet contains 31 antique-cut Burmese rubies (totaling 60 carats) possessing the deep, highly-valued color called pigeon’s blood. Burma, particularly the region around Mogok, has been a main source for rubies since the late fifteenth century. Rubies from this region are known for their rich and vibrant color, which is why the term “Burmese Ruby” is synonymous with the finest color rubies. A red to slightly purplish-red color, that is medium-dark in tone, with the vibrancy of the color enhanced by a red fluorescence is called pigeon’s blood. The rubies in this bracelet were taken from another piece of jewelry and reset by Harry Winston, Inc., in 1950. The original cuts were retained and the stones were reset in a 3-row platinum bracelet with diamonds. The accompanying 107 pear, marquise and round brilliant cut diamonds, total 27 carats. This beautiful bracelet was donated to the Smithsonian in 1961 and is on display in the Gem Gallery at the National Museum of Natural History. - See more at: http://geogallery.si.edu/index.php/en/1002085/burmese-ruby-bracelet#sthash.2b3BVBHt.dpuf
