Is it a club or a clover? I'm never certain how to determine which is which, but it's cute, antique, and diamond set, which is good enough for me. 
Converted from a late Victorian brooch, this motif (whatever you call it) is set with old cut and rose cut diamonds, and crafted in yellow gold and silver.
We have added a recycled gold 5mm jump ring in our usual style. 
Tested as 9ct gold and silver 
Weight approx 0.90g
