Monday - Friday: 10am-7pm
Welcome to The Diamondaire experience. We are a full service jeweler that is located in the heart of downtown St. Charles close to the river and plenty of entertainment. We are known for our custom work and feature some of it in our gallery. Most of our custom work starts with your imagination and we just run with it. Every diamond is different, just like every individual and we enjoy making unique pieces for unique people. Our site skims the surface of our in-store merchandise and offers some great deals on some overstock items online. Walk-Ins are welcome to view our cases but if looking for an engagement ring or custom piece, you’ll benefit from a private viewing in our diamond salon.
