Costello Jewelry Company - Naperville (IL)

5 /5 James Caruso: From the inception of our first visit as a couple to Costello Jewelry Company . . . to the very present—just days after our wedding—Trisha has worked with us every step of the way and has made our entire customer experience BEYOND extraordinary and beyond exceptional. We were fortunate to not only work with the best of the best, but we discovered in Trisha a person who has the highest integrity and an even bigger heart! Here are the words to describe our experience at Costello with Trisha and her character: Personable, professional, an eye for the “right contextual fit” for the customer and their needs, affable, caring, encourager, great communicator, beyond helpful, pleasant to be around, amazing, a joy to work with and speak with, and the list goes on. We were also blessed to have met Maureen, who was a great, great encourager and supporter alongside Trisha. Trisha and Maureen have helped to take our relationship with Costello jewelers to new Heights. I, James, have been a customer of Costello Jewelers going back 1998 and now a customer with Katherine for the last eight years as a couple. I want to give a special shout out to Jose who has been at Costello as long as I’ve shopped there. I see that gifted artisan working with amazing skill and artistry every single time I’ve been to Costello. He is one of the main individuals who helps to create and refine the jewelry that the Costello customers have come to know and love. Where would an exceptional jeweler be without an extraordinary artist like Jose? We are so grateful to the Costello family for their fine locations and even finer business and hospitality. We always appreciate their family and spiritual values and always love the meaningful mailers we receive, especially at Christmas time!

5 /5 Marianne - Italianwifey: I’ve been coming to Costello Jewelry in Naperville for years from purchases to repairs and cleaning. I love that my jewelry does not leave the store when being repaired. This is the first time I had an original ring designed, though. I worked with Marino Costello on the design process. As an anniversary gift, my husband wanted to buy me a ring, but I decided that I couldn’t give up my original engagement ring and wedding band so I had a new ring designed utilizing the diamonds. The process was interesting. I looked at rings in the jewelry store to get an idea of what I wanted and then we proceeded to the design process, Marino sending me CAD drawings and then a wax ring was made where I tried it on to get an idea of the design and dimensions. My new ring is gorgeous! Marino is a fabulous designer and so easy to work with. I appreciated his attention to detail and his quick responses to my emails. The design process was fun. I love that Marino designed such a special ring where I still have the original diamonds that my husband gave me 20 years ago. I highly recommend Costello Jewelry!

5 /5 JP Liquors: I recently visited Costello Jewelry Company to have five of my watches fitted, and I couldn’t be more impressed. The entire process was smooth and effortless — they handled everything with ease and professionalism. The staff is incredibly friendly and welcoming; they truly make you feel like part of the family from the moment you walk in. Whether you need jewelry repairs, custom pieces, or any type of jewelry service, I highly recommend Costello Jewelry Company. Their attention to detail, genuine care for their customers, and quality of work set them apart. I’ll definitely be returning for all my future jewelry needs!

5 /5 Bill Ossler: Stopped in Costellos to see if they could size a smart watch I received for Fathers Day. I spent around 2 hours trying and got a link off but couldnt get another or put it back together. I dealt with Alexander who greeted me immediately, offered me a water, and then took care of it in approximately 5 minutes. Great place to deal with. I need to get my wifes ring fixed and cleaned up and I know where Im taking it.

5 /5 Bridget Dervin: We had the privilege of working with Alicia at Costello Jewelry in Naperville on a very special project. She helped us redesign my engagement ring, reset a three-stone ring, and select a new wedding band that beautifully tied everything together. Alicia made the entire process such a joy—she’s not only incredibly talented and knowledgeable, but also warm, fun, and an absolute pleasure to work with. Her design sense is truly exceptional, and she brought so much creativity and care to every detail. Ive trusted Costello Jewelers for years with jewelry cleanings and repairs, and their level of care and attention to detail is unmatched. Every time I bring a piece in for cleaning, I’m reassured by the thorough inspection and the professionalism of their team. The staff at Costello’s is warm, welcoming, and genuinely helpful. Whether you’re making a major design decision or stopping in for a quick service, Youre always welcomed with kindness and genuine attention.
