Big Fan of Derco Jewelers

Ohan is the owner of this store and the stones and the people working there are amazing. This was a family business he started being responsible for at 17 years old! He hasn't failed because he's probably in his 70s now!

The best experience at Derco!

Lorraine has been a key part of the last 1.5 years for my husband and me. Lorraine is amazing. We met Lorraine at Derco when we first started shopping for my engagement ring. Then I didn鈥檛 see Lorraine until I had a gorgeous, sparkly new ring on my finger about 4 months later. Once we were engaged, I learned about all of the hard work that Lorraine and the Derco team did to make sure my ring was exactly what my husband wanted. From there, she helped us design our wedding bands and put that same work into both of our bands. All of the rings we have bought from Derco have been completely custom with intricate designs that most other large jewelers wouldn鈥檛 be open to working on. Lorraine always encouraged us to design whatever we wanted and she would work with us to assess pros and cons for different options. I鈥檝e never met someone so patient and willing to help. We鈥檙e actually going to miss buying rings from Lorraine!

We happened upon this store while strolling through the maze of jewelers in the GiftCenter & Jewelry Mart.
The bustle inside immediately got us curious about what they could offer within.
For one thing, the variety was almost overwhelming. We were thinking about a colored sapphire as the main stone, and they had EVERY hue imaginable, from rich blues to zesty pinks. The color decision took a few weekends to straighten out because everything looked so lovely! :D
The staff was another hook-- within a few minutes each time we entered, someone with a nametag tried offering us a little bottle of water or mint! Although it took a while to secure a personalized consultation, the fact that people still came around to check on us was a very nice touch. :)
The Salesman we spent the most time with was named Jeff, who did his utmost to make us feel welcome & give the best pointers for our design decisions. When we decided on a pale yellow oval sapphire, acknowledging that the current variety was a little narrow, he assured us, "Come back next week, and I'll have some better ones ready."
That next trip within would be one of the last, for he prepared not two, not four, but FIVE sunny yellow stones for us to pick from! From that batch, we found The One & quickly designed the remaining bands. The price for both the beautiful 3.25 carat stone w/ the diamond band & matching Wedding Band cost just below 3500-- a breath-taking bargain in the City!
We left feeling like we won the lottery, not just for the end result, but for how easy and fun Jeff made the process feel.
When searching for a unique (but amazingly affordable) symbol of your partnership, we highly enjoyed our experience at Derco, and we hope you will too! :D
