This piece was a bit of a labour of love. 
 
The trombone links were part of a guard chain which had some damage elsewhere, and I wanted to use them. I had platinum joining links handmade to make this gorgeous 2 tone bracelet, complete with the original dog clip. 
 
Tested as 9ct gold (rosy in hue) and platinum. 
Weight approx 4.20g 
Width of links approx 2.2mm
Length approx 7 1/4 inches 
Very good antique condition, a couple of slight dents.
