I would definitely recommend MDC Diamonds

I would definitely recommend MDC Diamonds to anyone in the market for an engagement ring. The whole process was quick and painless. I designed the ring I wanted on the website but my soon to be fiancé and I decided to go to the office so we could actually see the different carats and colors side by side. Moishy was super helpful extremely knowledgeable and easy to work with. He helped me find a really beautiful diamond (1.5 carat D color marquise SO PRETTY) that was within our price range. We needed the ring within a two week time frame (which I was in a bit of a panic over) we ordered the ring June 28th and got it July 9th which was earlier than I expected! I was able to text Moishy to stay updated throughout the entire process he was very responsive, so nice and really just great to work with. The ring arrived today and it is just beyond stunning it took my breath away even the ring box itself is beautiful (it has a light!) they absolutely exceeded my expectations! *Note: For the inexperienced engagement ring buyer take the extra time to get sized and go look at the actual diamonds. I would have ordered a ring a full size too big in the wrong color left to my own devices! I had no idea what the difference is between an M color diamond and a D I just saw that you could get a bigger diamond for the same price the further you went. The M i saw was actually a very pretty yellow hue but I had no clue there was such a big difference in color! I also thought I wore a size 7 or 7.5 and I needed a 6.25 so definitely work with a human if you’re new to this!
