Lot Details
Two Demantoid Garnets
Ural Mountains, Russia
Due to its high refractive index and equally high dispersion, the chromium bearing variety of andradite garnet (named after the Brazilian mineralogist J.G. de Andrada de Silva), was called "diamante", the Flemish word for diamond, hence the derivation of its present name demantoid. Found only as small crystals in the Ural Mountains of Russia, the premier world locality, gems over a carat in size are uncommon. The color can range from a dark yellow green to the rich, deep green of this stone, the result of chromium. Faceted demantoid garnets frequently contain characteristic radiating needle inclusions that are termed "horsetails" which are inclusions of byssolite. With a perfect shade of green neither too dark nor too yellowish this pair of gemstones are cut in a classic circular brilliant style. They are indeed a rare and exceptional garnet for those born in January. Suitable for mounting as a pair of earrings, these two circular-cut stones exhibit all the most desired characteristics of fine demantoids from this historic locality. It is rare to find demantoid garnets in sizes of over 1.0 carats. (2)
Weighing approximately 2.41 carats and 2.44 carats and each measuring approximately 8.0 x 5.0mm
