My husband didn't want your typical wedding band, so we went into Things Celtic to see what designs were available. He ended up finding a ring he loved. It had to be ordered from England and when we ordered it, we were guaranteed it would fit. When it came in, it was too large, and the owner stood by her guarantee. Despite the fact it was already engraved, she ordered us another ring, in a smaller size, and didn't charge us a penny for the second ring. The new ring fit wonderfully and we're very happy.
While not specifically a "wedding" vendor, Things Celtic was the only place that had wedding rings that jumped up and caught my attention. We wanted something special- a little more unique- than the standard plain gold bands. Our rings are white gold with beautiful celtic knotwork on them, and we love them to pieces. If you like jewelry (or other things) with a celtic flair, then this is an excellent place to look.
