Theo's Jewelers  is a family owned business since 1977.

Theo began his business at 5 North Wabash in Downtown Chicago's Jewelers Row. Soon after his sons joined him in the business bringing fine quality jewelry with a personal touch to their customers. In 2002 Theo's Jewelers relocated across the street at 29 East Madison Chicago, IL. Suite 1800. At Theo's Jewelers we believe every customer is special. That is why we give you the attention you deserve. Generations of families continue to come back to Theo's Jewelers because we care. At Theo's Jewelers we believe every customer should know the 4 C's of buying a Diamond. That is why every customer who comes to Theo's Jewelers is taught about their Diamond BEFORE they make a purchase. Our belief that we have stood by for over 25 years is that an informed customer is a happy customer. We hope that once you meet our family you will become our family.
