Since their introduction to the jewelry industry, laser welders have been lauded for their speed, accuracy, and convenience of use. Retail stores and job shops have made sizable investments in these machines, which are guaranteed to simplify day-to-day repairs such as fixing damage next to stones and cleaning up porosity in castings. But it has only been in the last few years that the technology has started to turn up in higher volume production settings. Now, however, as laser welders become faster, more user-friendly, and suitable for a wider range of jewelry applications, they are finding new homes as standard equipment on the manufacturing shop floor....

Standard yellow gold alloys which are based on gold-silver copper can be used for many production processes. They could be called ‘all-purpose’ alloys. However, optimising the alloys for the particular manufacturing process to be employed is possible by use of other alloying additions which can influence relevant properties such as castability and grain size as well as the mechanical ones, for example, strength, hardness and ductility. Only a few elements (e.g. zinc, silicon, iridium, cobalt) have proved to be useful additions for modifying carat gold alloys without detrimentally changing other relevant properties....

If you have never manufactured with platinum and you think that you are ready, if you manufacture with platinum, but you have not capitalized on the growing potential of the bridal market, even if you are successful at manufacturing platinum bridal jewelry, I hope some of what is contained in this paper will be of help to you. I have been involved in wedding ring manufacturing for about 25 years. For the last eight years, I have committed a majority of my time to designing in platinum, and platinum and 18-karat gold combinations. I have always looked at my designing successes in our industry and equated them with my desire to explore. As a result of my last decade of studying, platinum and I have become great friends....
