Here is a magnificent Sterling silver rose quartz ring by the Danish master silversmith Niels Erik From (see bio).  The oval cabochon cut stone is set in a substantial frame, hollowed to reduce weight.  The ring band is slightly misshapen and has been cut, doubtless to allow an adjustment to a different finger size. 

Condition: Excellent - no visible damage to top, band cut and misshapen

Marks: From 925S

Size: currently resting at finger size UK P, US small 8, Eu 57, but will adjust several sizes up or down.  Top of ring is 2.5 cm (1") long

Year:  1960s?
