The Diamondaire

"Because Remember Gentlemen...Size Does Matter''

The Diamondaire website provides a small taste into the magic that happens within the store. On our site you can purchase fine sterling silver pieces and some marked down merchandise along with viewing some bridal jewelry styles. But if your building and engagement ring or have a special jewelry design, then you want to come in. Our bench jeweler is a dinosaur and all our employees are trained though the Gemological Institute of America. The staff has access to thousands of designs and loose diamonds to build your piece. Experience the fun of buying a diamond and let us show you how we find value.

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.
