Diamond 'string' ring, JAR, Paris

The oval diamond weighing 16.04 carats, set within a diamond 'string' platinum mounting, size 6, maker's mark, French assay mark.  With signed box with monogram LMS.

Very good condition with almost no apparent wear to the mounting. Please see GIA report # 2105794032 stating the 16.04 carat oval-cut diamond to be F color, SI1 clarity. The diamond is slightly flattened on top and bottom, thereby presenting a very pleasing, slightly cushion-shaped outline. The numerous single-cut diamonds together weight approximately 0.90 carat, F-G color, VS clarity. The shank registers as a size 6 on a mandrel, but accommodates a larger finger due to its oval shape. The diamonds set on the shank restrict sizing.
