"Just got a beautiful new chain for my 20+ year old necklace. They attached the silver medallion and polished everything up so it looked like brand new! I don't know why I waited so long! I'm not much of a jewelry wearer myself but the next time I need a gift for someone I'll be coming here!"

"My wedding band & engagement ring were stolen (originally purchased @ J Alexander's) so I went back last week. Although I was focused on Vintage rings, Lexi showed me a stunning London Blue Topaz Engagement ring. This ring is a dazzling optical illusion. It's deep blue, its green, etc. the kaleidoscope of colors allows a new ring every day. The offset is a ring of diamonds. The wedding band wraps around the ring all created by the genius of Lexi. The pricing is reasonable. The staff is knowledgeable and customer service is extraordinary. I have asked Lexi to design a different ring. I am very pleased and I haven't previously written a 5 star review. Thank you for taking a sad situation and creating a fabulously happy couple."

"John and Christine are wonderful. I recently had some work done on my ring. When I got it back one of the prongs caught on things. I brought it back and they reviewed and fixed the problem! Great experience, and they are both so easy to speak/work with. I've been looking for a good jeweler, but I found my new jeweler at J. Alexander Fine Jewelers! Thank you!"

"J Alexander Fine Jewelers has real jewelers on the premises, unlike most chain jewelry stores typically found in malls, and the only thing better than their excellent custom work is their very excellent customer service. Here are pictures of my custom engagement/wedding rings set done by J Alexander and their sister store, and of a custom diamond Initial necklace they made for me. They also customized some pieces of inherited jewelry for me, using diamonds from some pieces I inherited (and did not wish to keep) that they set into other pieces I inherited (which had no stones), one of which (the Star of David) is also pictured below. The last picture of a very unusual piece is a necklace with a pendant containing a fire opal and druzy with both natural (textured) and polished (smooth) portions of the same piece of druzy."
