A Stunning Champagne Cubic Zirconia!  This stone is set into a simple 925 Sterling Silver basket mounting.  The stone weighs in the neighborhood of 2.3 carats, and measures 9x7mm.

Look closely at the prongs, and the rest of the setting -- we use a nice, thick structure (you don't want massive, but you don't want cheap stamped out stuff either) so that your jewelry will last and last.  (Your daughter will love it when she inherits this from you.)
