Diamond Bow Ring
Really easy to wear late Victorian 18 carat gold ring.
The central square mount with a diamond shaped aperture set with an old cut diamond with tiny foliate engravings in each corner, 
On each shoulder is a gold bow.
The diamond is about .4 carat
The inside of the band is hallmarked for 18 Carat London. Makers Mark indistinct. (no date) 
Shank 6.5mm wide all the way around - so great for stacking.
Size 8.5 but can be sized (has previously been sized)
Circa 1890 - 1900
