An absolutely stunning finger full of antique diamonds - there's nothing like it. 
This gorgeous ring features 5 graduating old European cut diamonds, with rose cut diamond points set in between them to "fill the gaps"
The setting is hand carved with beautiful scroll work, which has very minimal evidence of wear. 
Tests as 18ct gold 
Weight approx 4.34g 
Total diamond weight approx 1.75ct (calculated in settings) the centre being approx 0.65ct. 
Diamonds are nice and lively, with some inclusions common in stones cut during this time. (I would say I1/12 clarity) 
Finger size K (Approx USA size 5.5) - this could be sized up or down a couple of sizes. 
Excellent antique condition  - evidence of a historical resize, but very well done.
