Coast Diamond Featured Retailer: Costello Jewelry Company in Naperville and Glen Ellyn, Illinois


Back in 1979, a talented businessman and jeweler saw an opportunity to provide “real” jewelry at a fair price, display it in a store staffed with skilled and creative jewelers, GIA graduate gemologists and experienced jewelry experts. This businessman, Joe Costello, had the foresight to serve the customer with the finest jewelry styles and brands at reasonable prices at his first store. Today, Costello Jewelry Company helps customers find the perfect jewelry gift at two gorgeous stores in Naperville and Glen Ellyn, Illinois. Costello Jewelry Company continues to win numerous “best of” awards and focuses on the customer’s needs, not the sale. For these reasons Coast Diamond is honored to name Costello Jewelry Company this week’s Featured Retailer.

Residents who live in the Chicago suburbs of Naperville and Glen Ellyn shop at Costello Jewelry Company for their fine jewelry and watch needs, and couples in love visit Costello to find the perfect Coast Diamond engagement rings, anniversary rings and wedding bands. While the halo setting is always a popular style, customers still love this traditional solitaire setting designed by Coast Diamond, ready for a one carat center stone that a diamond expert at Costello Jewelry Company will help select:

Coast Diamond Classic 6 prong Engagement Ring (LC5270)

And Chicagoland brides-to-be who desire a vintage look have made this Coast Diamond halo, style number LC5257, a top selling favorite at Costello Jewelry Company:
