Royal Brierley is a fine cut glass ("cut crystal" for marketing purposes) brand, owned by Dartington Crystal and based in North Devon. It is one of the oldest crystal glass brands in England.
Many of the creations became quality museum pieces. The trading name Stevens & Williams was used until the 1930s when the company became Royal Brierley Crystal to signify its royal warrant of appointment as glassmakers. The first royal warrant was awarded by King George V and the most recent by Charles, Prince of Wales.
