Cocktail rings do not follow any convention in terms of design or material. The name originated in the US in the year 1930, when cocktails were illegal under the prohibition laws. In other countries, these rings were called ‘dress rings’ because they were meant for impressing observers on special occasions. In the beginning, the diamond cocktail ring vintage type was worn to show off a wearer’s wealth, with most centerpieces having a 3-carat stone or larger.
