THE BEST EXPERIENCE!
I was recently shopping for an engagement ring and tried a few different stores. I was disappointed as they felt very impersonal and found myself standing in lines like a “cattle call.”
Then, I came across the big Robbins Brothers sign, shining like the golden arches!
Mary immediately greeted me as I entered, exchanged pleasantries, was offered refreshments, and she took the time to get to know me and what I was looking for.
Mary was very knowledgeable and invested, talking me through the process from picking a diamond to the finished product. I was even able to work with Mary and Tien, a ring designer in creating a custom-made ring!
This was by far THE BEST experience I could have asked for when buying such a life-changing piece of jewelry.
I highly, highly recommend choosing Robbins Brothers, not only for their massive selection, but unmatched customer service.
Thank you so much Mary!!!
My fiancée thanks you also =)

I first came to Robbins Bros. in Fullerton to look for an engagement ring. I checked out a few other shops but nothing clicked. Felt like they were trying to force rings on me. But not at Robbins. The staff is very kind and friendly, especially Eric, who is top-notch at what he does. He never made me feel pressured and actually TAUGHT me how to find the right item for my girl. As someone who teaches for a living, that means the world to me.
My fiancée and I came back to Robbins for the wedding bands and we couldn’t be happier! 10/10 recommend!!

The staff at the Robins Brothers in Fullerton is awesome! I went in with some pictures of rings that I knew my fiancée liked, and they took the time to go through all the cases to help find me the perfect ring! I was pretty nervous going in because I really didn't know a lot about what I needed but they are super friendly and patient and I couldn't be more appreciative of all their help!
