The Mercury Mist Topaz, a titanium treated natural topaz, showing the most absolutely blazing pastel blue/gold/pink/silver/whatever you've ever seen.

These stones are set into a wraptight setting, hanging from 14K Threaders!   Notice the thickness of the gold in the mounting.  These are substantial, without being weighty.  I like my stones well protected, and I assume you do too!

This is a good stable setting that won't set you back a month just to get a pair.
