I come in here to get gifts for my sister who lives in Flagstaff and does not have access to this kind of store. They always seem to have the things she asks for and seem well stocked. They have always been nice to me when I go in, but I see a lot of bad reviews here and I think I know why.
This store feels very much like the SCA, or any other historical-focused organization. In those sorts of places, you need to 'earn your respect', in a way.
I'm not a jeweler and so they don't bother to look at me one way or another.
But If you go in this store as a jeweler, be aware that they are probably sizing you up when you come in. These people may want either evidence that you know what you're doing, or willingness to ask them questions and have them share their knowledge with you. Those sorts of places can have little respect for amateurs unless the amateurs come in with a willingness to acknowledge the expertise there and ask to have some of it.
That attitude can come off as pretentious or demeaning, but really it's just a very old-fashioned way of thinking. And jewellery is an old-fashioned art.
Hopefully that helps if you are a jeweler in the phoenix area looking for some supplies. Don't go in this store expecting modern customer service, because most people in this site have not found it. Pretend you are in the Middle Ages, and you are an apprentice going into a skilled artisan's store. That artisan probably demands respect in a way most modern people don't. It may seem backwards, but you may be able to tap into their knowledge if you pay the price of admission.
