Costello Jewelry Co.

Costello Jewelry Co.

In 1979, Joe Costello turned his passion and knowledge for fine jewelry into a thriving, client-centered business.  For the past 36 years, Costello Jewelry has grown in ways we could never have imagined.  Our artistic, on-site jewelers utilize top-of-the-line equipment to hand-craft the design of your dreams.  We find nothing more fulfilling than seeing our beloved clients brought together over unique, artisanal jewelry pieces.  Whether you choose a piece from one of the top designers we have spent decades building relationships with, or a piece that you yourself create alongside us, we will be with you every step of the way.

In addition to helping you procure your dream jewelry, we are here to assist you in maintaining or recreating your favorite heirloom pieces.  Our in-house shop is equipped to help you with ring sizing, prong replacing, stone replacing, and laser welding.  See us in Naperville (33 W. Jefferson) or Glen Ellyn (474 N. Main St.) for jewelry appraisals, gem identification, hand engraving, and so much more.

At Costello’s, we love love.  Passion, adoration, and life-long relationships are our motivation.  Impeccable jewelry is our result.
