We've come a long way since 1948 when Robert Haack himself, set out to become a successful and esteemed area jeweler.

Services
Most insurance companies request for you to have a jewelry appraisal done. Well, at Robert Haack Diamonds, we can help! We have a trained staff that can write up your jewelry appraisal and for high end jewelry pieces, we have graduate gemologists on staff. We can appraise any type of jewelry and makes no difference on where you bought your item from.
Everywhere you look today, 3D technology is starting to radically change the way we live from how everyday products are designed and manufactured to how we experience major motion pictures. And now, the innovative new custom design system at Robert Haack Diamonds brings 3D technology to the ancient art of jewelry making.
You might have seen us on television (and not just advertising!) Robert Haack Diamonds has repeatedly been invited to participate in news pieces to inform viewers how to sell their gold.

Given our reputation of fairness, channels 4, 6 and 12 independently featured owner, Bret Eulberg, extolling sound advice that included the hazards of shipping your gold while encouraging that all clients 'shop around' town, prior to selling their gold for the best deal.
Robert Haack has over a thousand pieces of jewelry at each location, both locations have a unique stock, meaning you need to visit both stores to see a HUGE collection. We offer many different vendors and their lines (plus we make custom jewelry). Robert Haack Diamonds stocks approximately 100 pieces from S Kashi and Sons, a jewelry industry leader known for creating innovative designs while combining top quality workmanship.
Unlike the song, we believe diamonds are far more than just "a girl's best friend." Robert Haack Diamonds knows that each diamond purchase is a significant investment of heart, soul and hard-earned money. That is why we are committed to educating our entire staff and clients about diamonds - from the characteristics that enrich their value to the proper care for them.

No pressure sales … having a gold allergy (yep, I’m allergic to gold) Leslie took her time to listen and understand what was important to me when deciding on a new ‘platinum wedding band and engagement ring’!… With a little research and great recommendations I’m in love with my new bling - thanks to my Hubby and Team Robert Haack💍❤️

I was very pleased from start to finish. They were professional, helpful, knowledgeable, and also sent me on my way with a beautifully polished and buffed ring. I hardly remembered that it could look as beautiful as it did! I would definitely go there again for my jewelry or estate needs.

I just discovered Robert Haack Diamonds this week and I absolutely LOVE the company. The owner, Brett, and his staff are patient and personalize the shopping experience. I’ve gone back four times in a week and… I bought 8 pieces and counting. I don’t think I’ll shop anywhere else for my jewelry again. The deals are so great, but the people-centered atmosphere keeps me coming back. The way a company treats you is important. Thank you for making me feel like family ❤️ 💍 💎. I’ll be back soon!

Simply after reading the reviews and how they blame the customer for their mistakes or even make excuses for carelessness, this is a place I would certainly not conduct business with.
