Created Red on Brown Opal, well cut, pretty Bright Red and Green Fire on a Brown background.
 
Totally gorgeous, and fraction of what real ones would cost -- but you pretty much have to be a jeweler to tell the difference.

Very pretty, and with a single CZ accent at the bail.

This stone is set into a sturdy 4 prong basket.  We cast our own mountings and will never use flimsy "snap tight" stuff...  It allows the most show of stone for the least expense in silver. It's a good stable setting that doesn't set you back a month just to get one.
