Hi all, I have been in the jewelry business for over 20 years now and previously owned and ran a production manufacturing company which created prototypes, molds, and cast and finished jewelry for designers throughout the US. We'd cast in a variety of metals using both lost wax and spin casting methods. After the sale of my business, I simplified and am now a jewelry designer, creating custom CAD designs, models and pieces for the trade as well as for my own line.; http://www.harryhamilldesigns.com
