Hallmarked French dog mark for Platinum, tete d’aigle mark on pin, numbered 30299 with original fitted case. H. 10.6 cm, accompanied by the original drawing and letter signed A. Van Cleef & Arpels dated 12 January 1928. Gross weight approx. 17.5 g Graded and measured in mount Note: Van Cleef & Arpels had been synonymous with French luxury and haute jewellery for over a century. Their timeless pieces have been worn by style icons such as Elizabeth Taylor, Grace Kelly and the Duchess of Windsor. Van Cleef’s impressive reputation is due to their unique sense of detail, frivolity and femininity, which is evident in this beautiful feather that has been turned into diamonds, set in platinum. Look at the perfect angle of the quill and the gentle, random overlapping of the plumes, that lends this piece its asymmetrical perfection.
