I am a jeweler and jewelry designer. I have a gallery in Mill Valley, California where I sell my work and a few wholesale accounts left over from the days when I worked the shows and went on the road. I work in platinum and 22k gold with other karats used as needed and as accents. I have been making jewelry and in the jewelry business for over 30 years with experience in a variety of areas. I know I'm a hardcore geek when I find myself up at 2 in the morning, fascinated, reading the blog of a guy doing tests on a new type of silver. But then, you don't do this work for this long unless you're really interested. So I love this forum...; -
