I cannot recommend Costello's in Glen Ellyn enough! My stroller completely bent a silver engraved plate that wasn't mine like a taco. I was completely stumped on what to possibly do to fix it and was so nervous to tell the group it belonged to that I had ruined it. I brought it in to Costello and they accepted the challenge. They completely fixed it and now you would never know anything happened to it. Not only did they fix it, but the service and communication was great! I will certainly be going back there again and again!

I had a horribly tarnished silver necklace that needed cleaning. So I brought it in to Costello Jewelry thinking it would take a week or so to clean, but the woman behind the counter (I don't remember her name) cleaned it in minutes and above all didn't charge me a thing! What a nice surprise! I appreciate the gesture and the personal attention.. thank you!

Costellos is the only jewelry shop in the Western Suburbs my husband and I trust. We've worked with them to create an updated diamond ring, as well as creating custom earrings using existing diamonds/opals I had in not-being-worn jewelry pieces. Leslie, in specific, is patient, informative, communicative, and so helpful. All staff we've come into contact with is friendly. This is a go-to spot for any jewelry needs. Highly recommend and cannot sing its praises enough.

Really nice people. Ralph has extensive knowledge of watches also and took the time to identify a really old watch I brought in. The first time I went there they put a bent silver ring back into shape at no charge. When I find the right stone I'm going to have something custom made.

I had a custom pendant made and the customer service, design, and attention to detail were excellent. Many thanks to Ralph and Katie Rose for helping me make my vision a gorgeous reality.

The staff here is very polite. They were able to get my watch fitted for me very quickly and are very knowledgeable when it comes to jewelry. I will be coming back here again in the future.

I could not have been happier with Costello's and with Leslie! I wanted to use a local jeweler to buy an engagement ring. I walked Into Costello's and I'm very glad I did! From the moment I walked in, Leslie had me feeling at home and comfortable. I was very nervous and had no idea what I was looking at. She made the whole experience easier and enjoyable. She walked me through every step and always kept in touch when needed. I needed the ring by a certain date and she made sure I had it on time. The ring is absolutely beautiful and EXACTLY what my, now, fiance wanted! Overall, it was a great experiance and I couldn't recommend Costello's and Leslie enough! We talked about budget and wants and needs... she stayed under budget and got me everything I wanted. We needed it resized when we got home from our trip and they took care of it the same day it was dropped off. She remembers me and my fiancé's name, even though they only met one time when she dropped off the ring to get resized. She even followed up a couple weeks later to see how it was and if it fit better now that she's been wearing it for a couple weeks. 10/10 highly recommend both Costello's and Leslie!

I visited this store for a basic watch battery replacement and they were courteous, efficient and professional. They even adjusted the band for free. Simply excellent service!

Costello's has been a part of my family for many years. They have great customer service. We recently reset my diamond from my 34 year old engagement ring into a new setting that is just stunning. Leslie is the best! Friendly, kind and very patient. She explained the whole process to us and kept us informed every step of the way. You can't find a better place. Oh and she had my diamond solitaire earrings reset to an up to date setting and they are beautiful! I now wear them everyday!
