True custom design involves using the lost wax method. Using this method a wax is either hand carved or created by the use of a computer aided cad program and then cast in either gold, platinum or silver. After casting, stones are set and the finished product is polished. True custom design requires a great deal of talent, training and time. Remount, what some stores call custom design, merely involves selecting a precast mounting from a catalog and setting stones. Although true custom design is more expensive it is a useful tool in creating unique, one of a kind pieces or turning out of style sentimental pieces into a more wearable design.
