Best of Boston

Long’s wrote the book (The Diamond Book) on buying diamonds, and eagerly uses it to educate customers at regular diamond seminars. But when it comes time to pony up and buy the rocks, this is old-fashioned shopping—complete with meticulous, informative salespeople and some of the brightest gems around. As one of the few stores in the region with both AGS (American Gem Society) and GIA (Gemological Institute of America) certification, Long’s has not only a high-quality stock but also a knack for finding the right stone for each customer.
