Matt was super knowledgeable and helped us find a beautiful diamond and also a setting that was just perfect for me. I could hardly wait to wear the matching wedding band with it. ...
We went back after the engagement to purchase the groom's ring and Matt helped us narrow it down all over again. We were super happy with the service we received and would recommend CDI to anybody looking for an engagement ring and wedding rings.
Matt and his team are wonderful! I am completely in love with my ring!
Honestly the best jeweler in town! Matt won us over with his knowledge, experience, and his hand-picked diamonds. Not only are his diamonds all high quality, clarity, and amazing c...
uts, the prices are hard to beat as well. If you're on the fence regarding lab vs mined diamonds, definitely ask his opinion (he has both)!
If that's not good enough support about why you should choose him, consider this - he's been there for years. Whenever another customer goes into his store, I could always tell they were repeat customers from the area. His Google reviews are also 5/5 stars - go and meet him to see why!

AMAZING PLACE WITH AMAZING PEOPLE WORKING!!! My engagement ring was my late grandmothers, and this past June I took it there and they reinforced the prongs that hold the diamond an...
d restored the band. These amazing people made my ring look BRAND NEW!! Recently, I bent the band while wearing it, so I decided to take it to a jeweler that was closer to me (will NEVER do that again). That jeweler gave me the ring back more bent than before and the diamond/prongs were off center. I then IMMEDIATELY took it to CDI, where they were able to look at it and assured me that they will make it look new again. Just one week, I picked up the ring and it’s back to its former glory!! I am ever so grateful!! This ring means a lot for both me and my family, and we are all so happy with the work they have done!! They were able to fix another jewelers mistake (which says A LOT in my book). I will forever recommend everyone I meet to go there. And to top it off, they are all SO informative! They explain what they do, they give you the price upfront and if any other work needs to be done, they CALL BEFORE THEY DO IT!! THANK YOU THANK YOU ALL FOR BEING THE GREATEST JEWELER AROUND!!
I cannot recommend CDI enough!! Matt is so helpful and will be honest and straightforward with whatever you need. he helped my fiancé immensely and we will be going back again for ...
our wedding bands!

I get a compliment almost daily on my ring because it is so unique!! Its a Pearcut with a halo, half eternity band diamond raised setting in rose gold, with little "secret" diamonds underneath.
