This project is an investigation of material and processes in jewelry-making that combines hand-making with production methods derived from industry. The study examines how a studio jeweler, in this case defined as a practitioner who makes jewelry as a material and conceptual exploration, might adapt the production methods of industry to their practice.

Living in this high-technology era, the computer is pervasive item in modern life. The creation of jewelry pieces has also been affected by machines controlled by computers. If machines create millions of identical jewelry pieces, what will make the difference between creative and mundane pieces? This creative project is to pursue the use of machine-made objects and produce creative pieces of jewelry. Also, in order to gain practical skills and enhance my design skills, I designed many pieces of jewelry with 3-D software. / Department of Art
