I cannot speak more highly of Charles Koll Jewelers and the work they do. I purchases my fiance's engagement ring here and worked closely with Richard on designing the perfect ring. They are fair and provide expert consultation throughout the entire process. The final product was perfect. We also purchased our wedding bands here which were also custom designed and they will accompany her engagement ring perfectly. Everybody is so friendly at their office and their priority is customer satisfaction. HIGHLY recommend using Charles Koll as your jeweler.

Malcolm saved what was the most terrible experience with my first ring from another jeweler and I couldn't be happier. He took such good care of us and my ring is absolutely gorgeous. Thank you!

I am so excited to know that Charles Koll Jewelers- and, it's incredible team of designers and customer support staff- will be reopening soon! This family-owned business offers an elegant array of jewelry in a friendly atmosphere. I have been a customer for several years now, and can say that I always leave their store feeling thrilled (and, educated). I love the custom pieces I have ordered through Charles Koll- each one means a lot to me! My heartfelt thanks!

Excellent customer service - big thank you to Claire for her genuine support throughout the years. She helped my husband and me when we first got engaged by guiding us through resizing and repairs needed for a family heirloom wedding ring set; and most recently, she happily welcomed me in for a cleaning and consultation while they were still working on opening their new store location - all with a big smile. Her deep knowledge of jewelry, honest feedback, and warm disposition will keep us loyal customers for years to come. Thank you Claire!

I don't even know where to start other than to say that from top to bottom beginning to end these guys were amazing. We happened upon a sale and during their transition to the new location so it was perfect timing but ultimately my wife's ring was lost after 14 years of marriage and we were able to get it replaced with an even better ring for about the same cost and she absolutely loves it. Richard is phenomenal. Plus it is a family-owned business which is always nice. And as a business owner myself I critique pretty hard. :
