Here's what our customers have to say...

The fact that Ashley’s ring was ‘custom made’ is really what made the entire process. I’m assuming girls love any ring that they’re proposed to with, but knowing her ring is literally one-of-a-kind is something she is extremely proud of. Plus, it’s pretty cool knowing I was able to give her something nobody else has. She (and I) had a very good idea of what she wanted and Darren listened, understood, and then blew us out of the water. Being able to hand-select the stone, walk through the crafting of the ring/setting, and see it come to life was amazing. The Union experience was nothing short of fantastic. Darren exceeded any and all expectations. As a guy that had zero knowledge of the whole ring/diamond world, he not only schooled me as we went through the process, but he also made it fun and enjoyable. When I initially started the research process, I quickly found that everybody has a “ring guy”. I was told numerous times to be careful, it’s a shady business, etc. I assure you that anyone who ever asks me about rings/diamonds will be directed to Darren. Honest, genuine, and knowledgable is how I would describe him - not often words associated with people in the diamond business. And by the way, his prices are great and his product is exceptional.

Darren helped me create the ring of my dreams! His high attention to detail, exceptional craftsmanship, and incredible customer service made the whole experience seamless. If you are looking for an affordable retailer that will listen to what you want and give you the best deal, you shouldn’t look any further. I could not have asked for a better ring, and I have Union Jewelry to thank!

My experience working with Union Jewelry was incredible. I didn’t know the first thing about picking out an engagement ring for my future fiancee, let alone have thoughts on how to design it. It was all foreign to me. Darren walked me through the entire process step by step, and patiently explained everything I wanted to know about diamonds and engagement rings. I gave him a budget and an idea for a ring, and just a few days later, he sent me a computer graphic image of what the ring would look like. Two weeks later, I was down on one knee, presenting a gorgeous engagement ring to my girlfriend and asking her to marry me. It was very meaningful to her that we had the ring custom made. She had some ideas about what she wanted, and so Darren and I took those ideas and ran with it. She loves her ring so much and often gets compliments on it. There’s no other ring on Earth that looks exactly like hers, which is what makes it so special for both of us.

“When it was time to celebrate our 18th wedding anniversary with a new diamond ring, we knew Darren was the one to call. The diamond buying process can be full of anxiety, but we knew we were in safe hands with Darren. His integrity and honesty reassured us that we were getting the best quality diamond for our budget. He helped us find a gorgeous stone, and was patient as we settled on the final ring design. He helped us choose a classic, timeless design that I know I will love for years to come. The whole process was fun and exciting. I would recommend Darren and Union Jewelry to everyone.”
