I have "fixed" a whole lot of jewelry in my time. It's shocking to me the shoddy workmanship out here that people buy. It is ugly, it is full of dark, dull I grade IJ color stones and passed of as fine jewelry. The truth is? You just wasted your money on that piece of sh*t - and all that it's really worth is the gold we can melt it down into. Don't buy crap and regret it later. Buy quality - don't know what that looks like? Look at the masters - Vintage Tiffany and co., Harry Winston, Chopard, Jar, there are so many amazing old designs that really showcase stone setting - less metal more stones. Make sure any stone you buy is an SI1-2 or better and a GH color or better generally speaking. and, make sure you are dealing with a jeweler who will make it right. Takes the time to explain it to you - what makes good jewelry, how it performs and looks, how to clean and take care of it, and someone that stands behind their stuff.
Otherwise? wear a cigar band and move along.
