Well cut, with lots of blue sparkle, this totally clean stone would run about $4,000 if it were a natural Kachanaburi Royal Blue Sapphire... and yes, the color is THAT good.

This Lab Sapphire stone is set into a simple 14k gold basket mounting. The stone weighs in the neighborhood of 15 carats, and measures 18x13mm.

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.) 

It's a good stable setting that doesn't set you back a month just to get one.  There's no reason why these stone shouldn't last you for years, and dazzle every day of it.
