The British crown jewels contain the Cullinan Diamond, part of the largest gem-quality rough diamond ever found (1905), at 3,106.75 carats (621.35 g). Now popular in engagement rings, this usage dates back to the marriage of Maximilian I to Mary of Burgundy in 1477.

The earliest culture to begin managerial jewellery in Asia was the Chinese around 5,000 years ago. Chinese jewellery designs were authentic religion-orientated and contained many Buddhist symbols, a Engagement Rings authenticity which remains to this day.
