Just wondering if anyone has had any experience with ADCO? They are in Boston in the jewelers building. Seem honest and fairly priced, but i haven''t seen too many reviews in this forum. I''m looking for an engagment ring, and I''m a little skeptical to buy one online. I think id rather buy from a brick and mortar store just go my girlfriend will be able to go back to the store in case. Any help is appreciated! Thanks!
