Kornerupine is a rare born-silicate mineral that is very rarely found in gem grade.  It is highly pleochroic, and cut gems will often show more than one color when carefully observed.  This Kornerupine is a beautiful light green color, and shows a small bit of secondary orange, giving the green a slight olive tone.  The gem is very clean, with a few tiny natural inclusions not easily visible without a 10x loupe.

This Kornerupine is faceted in my “Bella” square cushion design and is extremely brilliant in the hand.  The gem weighs 1.59 carats and measures 6.2 x 5.1 mm.  Kornerupine is typically quite small, and gems over one carat are very rare.
