Antique Red Spinel and Old mine Cut Diamond Carved Band Ring Solid 14k Gold size 8

This is a stunning antique ring made from natural red spinel and diamonds. The stones are all cleaved (rather than modern day cut). The ring is not marked but guaranteed to be at least 14k gold, solid. There is beautiful hand carving work. 

You might notice there is a "crack" line in one of the spinel. This I believe to be from a twinning plane in the stone. It is secure but is noticeable (see photos).

The center spinel is about 6x5mm cushion, and the sides are 5x4mm. The diamonds are 5mm and total between 80-90 points total weight. The ring is a size 8 and weighs 5.1g.
