I'll try to remember/find the person from Etsy where I got mine. I love it, and it's very sturdy! I'll pm you when I find the name.
Also, I second the James Avery suggestion. There's one in Atlanta, and I have a beautiful charm bracelet from there. They also have lovely necklaces and other jewelry that's very well made. The specialize in keepsake jewelry. I don't think they do hand-stamping, but you should check them out.
****Update -here is the link to JLynnCreations on Etsy where I got my hand-stamped mother necklace. I love the one I put together and my husband got it for me for Mother's Day and added a few special charms. One word -the discs and charms DO tarnish a bit, which I really like because it gives it an antiqued look, but if that bothers you, be forewarned or contact the artist to find out what she recommends.
