Diamond cusp earrings
These are a rather special pair of silver and gold earrings with a sprung catch mechanism that holds on to the earring post of the diamond set stud.
You press the gold trigger on the top to release the stud and, lo, you have a pair of diamond stud earrings that you can wear on their own. Because of this I supply them with a set of silver butterflies as well.
The silver cusps are 15mm high and the diamonds are 3pt brilliants.
