Review for Magic Diamond - Lewiston Review For Magic Diamond - Lewiston Google User Aug 31 '17 at 23:28 Have now had two terrific shopping experiences at Cross Jewelers in Portland - first last fall, when I purchased a Maine tourmaline ring, and then again this September, when I purchased a lovely tourmaline necklace. Remarkable client service, so accommodating, and in both cases, there had to be modifications made, which were accomplished swiftly and professionally. I am, in a word, delighted. Bought some beach glass jewelry set in silver for a gift and a lovely souvenir charm as well. Well worth the visit! View full site to comment or like
