| Background White color jewelrys can be said to have been booming since a large number of diamond mines were discovered in the early 1900s. However, while demand for platinum increases over time, the production of platinum decreases, causing disruptions in supply. White gold, which is similar to platinum, is developed and distributed for commercial purposes when such a platinum substitute is desperately needed. Early white gold was not uniform in the type and content of elemental metals used as alloys, Gradually, the production method of standardized white gold will be created. According to the production method, it can be divided into nickel-based white gold and palladium-based white gold. However, nickel and palladium are not commonly used in modern white gold. Nickel causes contact allergens to cause harmful effects on the body, and palladium has soaring prices that have similar economic value to gold and cannot offer economic prices in a highly competitive modern market. Nevertheless, some luxury brand jewelery companies use palladium or platinum as alloy alloys in white gold jewelry. White gold produced in this way will have a clear white color without worry of discoloration. The white color is steadily maintained even without white plating, which means that luxury brands have kept their values.
Methods In the past, the palladium-based white gold alloy ratio was 4: 4: 2, which was made of 40% of gold, 40% of palladium, and 20% of other metals such as silver and platinum. Based on this method, white gold without plating was developed. And alloy alloy considering economic value was intended. Alloys made of 40% gold range from 9 to 10K, but this study attempted to study the white color of one of the most popular and jeweled 18K content. Since 18K is 75% gold, the remaining 25% alloy is the main experimental study on white color improvement. Several metal elements that induce white color are selected and alloyed with alloys up to 25%, the maximum ratio, to compare white color improvement. Among them, the subjects whose color improvements were made were studied whether or not there was any abnormality in the processing of the actual jewelry, the discoloration occurred over time, and whether the white luster was maintained even after the polishing operation. In addition, when expensive alloy material is used, it is produced by gradually reducing the alloy content in consideration of economical efficiency. By comparing and analyzing the created objects, the golden ratio that can achieve the maximum effect with the minimum value is presented.
Result Such research has disadvantages such as the high cost of alloys due to expensive alloys and the resulting increase in product prices, but color improvement can improve the quality of jewelry products and reduce unnecessary plating expenses. The retailer will be able to increase the stability of the display of precious metal products and will be able to construct a new color lineup of low priced existing white gold and expensive white gold. First of all, the seller's excuses due to the discoloration of white gold are unnecessary. It can improve sales performance and resolve dissatisfaction with consumers due to no discoloration. Consumers will also buy more jewelry.
Conclusion The beneficial effects of these studies are expected to be of great benefit to the jewelry market economy. It is expected to play an economic virtuous circle in all jewelry sectors, including the jewelry manufacturing industry and the wholesale and retail distribution industry. |
