Three generations of excellence in quality craftsmanship and outstanding customer service.

At Tobin Jewelers, we want you to love and cherish your diamond jewelry. That’s why we offer special benefits to those who come to us to purchase one-of-a-kind diamonds.

The Trade-Up Program

When you purchase a diamond at our New Berlin or Mequon showroom, it will hold its value – for life. If, at any point in the future, you decide you want to upgrade to a larger or higher quality stone, you will receive a credit for the full purchase price of the original diamond to put toward the purchase of a new stone.

This special offer applies to all loose diamonds, whether they are used for an engagement ring, diamond stud earrings, or any other piece.

The Engagement Ring Bonus

With the purchase of a center diamond from Tobin Jewelers, you will receive the following as part of your purchase:

  • 20% off on your hand-selected or custom-made engagement ring and wedding bands from Tobin Jewelers
  • Setting your one-of-a-kind diamond in your engagement ring
  • Complimentary ring sizing for your engagement and wedding rings
  • A certification from one the largest independent gem labs in the world
  • An appraisal for your insurance company so you can insure your future family heirloom. (We also will update the appraisal for you in the future at no charge.)
  • Laser engraving for most of our diamonds


Whether you're in search of a new piece for yourself, the perfect gift, or the engagement ring of your dreams, our third-generation experts are here to help. Visit us in Mequon or New Berlin today to see everything we have to offer!
