What should I look for when buying a diamond?

Our GIA-trained gemologists are on-site to walk you through the 4Cs — cut, color, clarity, and carat weight — so you can choose a diamond with confidence, not guesswork.

Do you buy gold, silver, or diamonds even if I didn't buy them from you?

Absolutely. We pay on-site, on the spot, for gold, silver, diamonds, and coins—regardless of where they were originally purchased.

How long does a custom design take?

Most custom designs are completed in about 4 to 6 weeks, from first sketch to finished piece.

Do you offer financing or layaways?

Yes—we offer in-house financing and lay-away options to make your purchase work for your budget.

Can you appraise jewelry I purchased elsewhere?

Yes. Our on-site gemologists provide appraisals in 4 days or less, no matter where the piece came from.

Do you offer free cleaning and polishing?

Yes! We provide free jewelry cleaning and polishing—stop in anytime.

What if I've already gotten a quote somewhere else?

Bring it in. We'll beat any competitor's quote, or we'll give you $20 just for the effort of shopping around.

About Our Jeweler | Greenfield, WI

Robert Haack Diamond Importers has been helping Wisconsin families find the perfect diamond for nearly 80 years. Founded in 1948 by Robert Haack, our store has grown from a single jeweler's vision into one of southeastern Wisconsin's most trusted names in fine jewelry.

Since 2007, the business has been proudly owned and operated by Bret and Marie Eulberg, who have carried forward Robert Haack's original commitment to quality, honesty, and old-fashioned personal service. We remain an independently and locally owned Wisconsin business—not a chain, not a franchise, just a family-run store that treats every customer like a neighbor, because that's exactly what you are.

Our showroom in Greenfield, WI, is home to on-site GIA-trained gemologists and a master goldsmith, so every diamond you consider and every piece we design is backed by real expertise, not just a sales pitch.
