Alfred Dunhill is a luxury English brand, specializing in ready-to-wear, men's clothing, leather goods and accessories. Founded in 1893 by Alfred Dunhill, it has belonged to the Swiss luxury group Richemont since 1999.
This cufflink and tie clip set is by Dunhill and dates from approximately the 1980s. The inlaid stones appear to be ferrite, a stone that Rolex used for some of its stone dials.
