Abstract

Recently, most jewelry design employ multiple prongs that grasp the front surface of the jewel to the metal frame To keep up with recent trends in fashion. jewelry manufacturers need to produce single-prong neckalces and earings constructed with non-precious metals. In responce to this demand, Ameth Development Division and The University of Seoul researched jointly and developed a technique for setting the jewel safely using a single prong with less weight. The setting process consists of making a small trench through the jewel at the mounting point and using a low melting point tin solder, to fill the trench and bonding with the prong. The application or this technology in the setting of a natural amethyst to a single 18K gold prong resulted in a 40% reduction in cost and weight and improvement of feeling for wearing.
