The study of silver metal used in the non-plated jewelry industry was found to be dull or black but it was a basic feature of silver. To react with air easily in Thailand. The hot weather must be maintained regularly. The concept that we can study the development of silver metal with resistance to tarnish to slow down will have a positive effect on the jewelry industry. The team has developed a concept to bring other elements to meet the potential. The element used here is palladium (Pd) because the palladium is in the same group as the nickel and platinum groups in the periodic table. It is a metal (Nobel Metal) which is very durable corrosion. Usually white is natural and when used to polish the skin is glistening and in most cases in the jewelry industry is often used as part of the alloy such as making the natural gold color close to the platinum. The authors performed the experiments by introducing silver metal with palladium in an appropriate ratio and tested it with artificial stone. And save the record. It is divided into 4 periods of 5-20 days in normal temperature. The results of the study showed that 92.5% copper 6.8% and 0.7% palladium had a shade of L value of 59% over 20 days. It can be used to produce silver jewelry at a lower tarnished rate. In the jewelry industry
