Queen Victoria’s Turkish Rosette Necklace. 

Queen Victoria was given a personal gift of a large number of diamonds by Sultan Mahmud of Turkey in 1838. The following year, the Queen commissioned Rundell & Bridge, the firm that held the royal warrant at the time, to create a necklace and earrings using some of the diamonds. Because of the provenance of the stones, Victoria referred to the set as “my Turkish diamond necklace and earrings”. 

The necklace featured three diamond rosettes – one large and two smaller ones – connected to each other by three strands of diamonds. At the back, two large oval diamonds connected via two rows of diamonds to the smaller rosettes on one side, and to the clasp on the other. The clasp itself featured a massive diamond in a frame of smaller stones. 

The earrings were equally elaborate and featured two small rosettes connected to each other with three rows of diamonds. Victoria was fond of the set and wore it to some of the most important occasions in her life, including her wedding and christenings of some of her children.
