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.

The term jinjuseon(眞珠扇), meaning literally a pearl fan, refers to a fan decorated with precious stones for use in royal wedding ceremonies. This study examined a jinjuseon housed in the National Palace Museum of Korea (NPMK) which currently lacks jeweled ornaments. In order to determine whether pearls or other gemstone settings originally ornamented the fan,the surface and composition of the gray materials remaining on the washers were investigated and the fan was compared with other artifacts decorated using similar techniques. The analysis revealed that the gray materials visible around the round rims of the washers contain tin-lead alloys. The traces of folded nails suggest that soldering was not applied. The remains of the infill observed in other artifacts with bezel settings indicate that this jinjuseon in the NPMK collection was produced using abezel setting technique wherein pearls or other gemstones were affixed by filling cylindrical bezels with tin-lead alloys.
