Charles Horner Silver Cluster Brooch from Chester, 1945.

The Charles Horner Silver Cluster Brooch from Chester, dated 1945, represents a piece of British jewelry history from the mid-20th century. Charles Horner, a renowned name in British jewelry making, was based in Halifax, West Yorkshire, and known for producing high-quality silver and enamel jewelry, including the famous "Dorcas" thimbles, from the late 19th to the early 20th century. The company's pieces are highly collectible today.

A brooch marked "Chester Silver 1945" would have been hallmarked in Chester, one of the British assay offices. The Chester Assay Office was operational until it closed in 1962, making any piece hallmarked there of particular interest to collectors due to its finite operational period. The date letter for 1945 in Chester hallmarking would help in verifying the authenticity and exact year of manufacture of the brooch.

Given the time period, a silver cluster brooch from this era would likely reflect the styles and design preferences of the time, possibly incorporating motifs popular in post-war Britain or reflecting the austerity of the era with simpler designs compared to the pre-war period. Collectors and enthusiasts of vintage jewelry appreciate such pieces not only for their aesthetic and historical value but also for the craftsmanship and story they represent.

If you're looking into the value, authenticity, or further details about this specific piece, consulting a specialist in vintage British jewelry or an appraiser familiar with Charles Horner's work and British silver hallmarks would be advisable. Additionally, checking with auction houses or collectors' forums could provide more insights into its current market value and collectibility.
