Brian is awesome! My (now) husband worked with him to design my dream engagement ring and he set us up with our wedding bands and wedding gifts to each other. He was so responsive and helpful and made sure we got exactly what we wanted. Highly recommend!

We had a wonderful time at Ultimate Jewelry Designs. My brother and sister-in-law gave it rave reviews, so we headed there when we were ready to tie the knot. All of the staff was knowledgeable and incredibly nice. I knew I wanted a rose gold engagement ring with a solitaire diamond, and Ultimate crafted a custom-made one that I love.

When it came time to search for wedding bands, we went to several stores. But Ultimate had the best prices and attention to detail. I got my fairytale ring — a rose gold band encrusted with diamonds. I heard that you have to leave a bit of ring exposed (i.e. no diamonds) just in case you have to resize the ring later. Other jewelers said they could do ½ or ¾ diamonds, but Ultimate was able to do 98 percent, and left just a tiny exposed space, saying they could work with that if I ever needed to resize it.

Whenever I'm in the neighborhood, I stop by because Ultimate offers free ring cleaning. It's so nice of them, and it's great getting that extra sparkle!

My husband got a white gold ring. Ultimate sized the width perfectly so that it looks great on his long fingers. We both highly recommend Ultimate!

A Great Experience!!

I wanted to get my wife's engagement ring reconditioned and upgrade the diamond for a surprise on the 20th anniversary of when I proposed. Years of resizing and just normal wear really took its toll on the ring. I worked with Brian who took all the time that I needed and allowed me to explain what I was looking for. He was able to find the perfect diamond for us and kept it all within my budget. I could not find the words to say how extremely happy I was with what the ring looked like when I went to pick up - it actually looked better than when I bought it 20 years ago! Brian's knowledge and his caring for the customer is second to none. You can definitely feel the family-owned atmosphere the minute you walk through the door which is what made this an easy process. I would highly recommend going to Ultimate Diamond to everyone
