That unmistakeable glow of patinaed 15ct is just the best. 
 
This oval, set with an old mine cut diamond, was originally a stick pin, which we have converted, adding a recycled gold jump ring. 
 
Stamped and tested as 15ct gold 
Weight approx 0.80g
Total drop approx 20mm
Width approx 9mm
Diamond tested as natural, earth mined diamond
Very good antique condition, with patina.
