Shank is 1.8cm. The decoration is 18mm x 1.2. 6mm wide so not too proud from the finger.
Worn once, it's a bit too big for me. It is a size UK R-S (bang in the middle on my ring sizer) which translates into a US 9, 19, 59.5.
Barely a scratch on it.
Bought at a fine jewellery auction so will include a screen shot of it.
It is fully Hallmarked for 9ct white gold, Birmingham 2011 with makers mark CR.
