This is a cold enamel Carnation pin by Exquisite Jewellery Ltd., of Solihull, Warwickshire, England.  It was one of their range of Birthday Flower Brooches introduced and extremely popular during the 1960's.  These pins came in two sizes with a flower for every month of the year!  This is the larger sized one! The Company also had a range of Leaf pins and matching earrings, as well as many other lines in quality costume jewellery. The  Carnation Brooch is the pin for October .  It has a silvery gold tone finish and has the classic "bow" tied around the bunch of flowers which features on all these designer pins. It is in good vintage condition.  What a great gift for anyone who has an October Birthday or just because you like it! Approximate measurements are  7cms (2.75ins) by 5cms (2ins).  This item fastens with a rollover type clasp.
