Yard first introduced asymmetrical cocktail rings, also known as ‘sport’ rings, in the 1930’s. They became increasingly substantial pieces of jewellery in the following decade, often set with sizable centre stones. A similar ring, differing only in the shape of the central diamond, appears in 'Yard:The Life and Magnificent Jewelry of Raymond C. Yard', by Natasha Kuzmanovic, fig. 313.
