Art Deco ring from Gleim the Jeweler.

A man presents his prospective bride with an engagement ring upon acceptance of his marriage proposal. Anthropologists believe this tradition originated from a Roman custom in which wives wore rings attached to small keys, indicating their husbands' ownership.

In 1477, Archduke Maximillian of Austria commissioned the very first diamond engagement ring on record for his betrothed, Mary of Burgundy. This sparked a trend for diamond rings among European aristocracy and nobility.

The sentimental Victorians popularized ornate engagement ring designs that mixed diamonds with other gemstones, precious metals and enamels. Often these rings were crafted in the shapes of flowers and were dubbed “posey rings.” Diamond rings crafted during the Edwardian era continued the tradition of pairing diamonds with other jewels, commonly mounted in filigree settings.

In 1947, De Beers launched its now classic slogan, "A Diamond is Forever." This campaign spurred even more sales. The implied durability of a diamond conveyed the meaning in the American psyche that marriage is forever. A diamond's purity and sparkle have now become symbols of the depth of a man's commitment to the woman he loves in practically all corners of the world.The opening of the DeBeers mines in Africa made diamonds more accessible. In the 1930s, when demand for diamond rings declined in the U.S. during hard economic times, the De Beers Company began an aggressive marketing campaign using photographs of glamorous movie stars swathed in diamonds. Within three years, the sales of diamonds had increased by 50 percent.

Diamonds still signify the celebration of a union and cherished memory, though more cuts make more styles an easy option for diamond lovers.

The History of Popular Cuts

Over the years, the most popular cut for diamond engagement rings has always been the round brilliant, consisting of 58 facets that divide the stone into a top and bottom half. Runners up include the princess cut, the emerald cut and the oval cut, with the cushion cut quickly gaining popularity as a recent trend.
