Antique Engagement (7/366)

This ring is emerald set in platinum surrounded by diamonds. It was given to me by my grandmother, for my wife's engagement.

Sadly, emeralds are quite brittle, and the antique setting wasn't up to modern life. The middle diamond on the right fell out once, and it was pure dumb luck that we found it. We brought it home tied up in a napkin, a bit like you do with your child's teeth when they fall out!

Emerald is formed from the mineral beryl, coloured by chromium and/or vanadium. Accordingly, it's this week's WBC entry.
