Here is a superb 15 ct yellow gold knife edge cut bar brooch set with a single cultured pearl bought in the early 1900s and still in its original fitted box that it was bought in.
The length is 45 mm. The pearl is 4.5mm near round. The weight is 2.7grams.  It is not hallmarked but is stamped 15ct. Tested at 14/15ct.
I had this brooch valued for insurance purposes at £300 SHRV.
A really lovely classic brooch in good condition. The photos describe it well but any questions please ask. Thanks for looking.
