I would like to hire an excellent goldsmith to make some custom jewelry for my daughters. In particular, I would like identical necklace pendants of my family coat of arms. Does anyone have a recommendation for how to search for a reputable goldsmith? Are there any accreditation organizations or certifications that I should look for? Mostly I want a skilled artist who can truly capture the essence in a timeless manner - heirloom jewelry that will be passed on for generations. Just because someone knows how to work with the metal doesn't mean they are artistic.
