This bracelet is set with a large central cabochon of Hematite.
The inside of the bangle is marked Sterling Denmark N.E. From 925S with the mark used in the 1940's and 1950's. The maker of the piece is Niels Erik From, a well respected silversmith and considered one of the greats in Danish design.
The bracelet secures with a sprung clasp which secures to the ring to one side of the setting. We would suggest it dates to the 1950's.
There are some scratches and marks to the silver to the sprung clasp as shown. The Hematite is highly polished and very reflective.
The bracelet measures 175mm around internally. The Hematite in its setting is 19mm x 25mm.
