This Paraiba stone is set into a simple 14k gold basket mounting.  The stone weighs in the neighborhood of 7 carats, and measures 14x10mm.  It is roughly the size of a dime, only oval.

Look closely at the prongs, and the rest of the setting -- we use a nice, thick structure so that your jewelry will last and last. (Your daughter will love it when she inherits this from you.)
