What our clients say

The Only Thing That Sparkles More Than Our Diamonds - Is Our Reputation!

Great people. Attached a band to my watch at no charge. When they do things like that it makes you know they are all about customer service.

John Gebbie

I have been shopping at the Diamond Jewelers stores for over 10 years and I have had only great experiences. The staff is knowledgeable and courteous. They always take time to make my shopping experience feel personal and they show genuine interest. I personally love watches and they always have a great selection to choose from. I recently purchased a new watch and I could not be more happy with it!!

Andrew Goldberg

Good low prices

CUBANCHULO149

Great place and reasonably priced. I got my wife’s engagement ring, wedding ring, my wedding ring, and a watch for her as well.  They are more than happy to work with you to find something that can match a specific item you may be looking for.  Staff is very friendly.

F.J.

The service and the salespeople were all amazing, they helped me right
away, and explained everything that had to be done to fix my ring.
The jeweler did an amazing job. Wonderful experience.

Patricia Dirusso
