Now, this, is a gem.  An aquamarine cabochon more than 19 mm x 13 mm x 12 mm thick and weighing in at 24 ct.  Gorgeous aqua blue set in solid 18k green gold on a handmade green gold chain.  Made for one of my most stylish of clients it also has a wee hook in platinum at the back to which she occasionally boosts up the colour even more by adding an earring drop from her collection of Disegno earrings.
