...the experience was great.

I purchased a ring from MDC, Black Diamond Halo Engagement Ring Twisted Pave Band in 14K White Gold, and the experience was great. I was already set on a diamond from another vendor, and they made the whole process of shipping the diamond to them (fully insured) easy, which gave me great peace of mind having never sent something so little and so valuable before. Moishy worked with me every step of the way, with updates on when they received my diamond when the ring would be ready, and when it had shipped again very securely packaged, insured, and tracked. MDC was able to customize the ring to platinum, and the halo was a perfect fit. The pictures on the website can’t do justice to the rings’ beauty in person. Of course, my bride to be was filled with tears of joy when she first saw it. I definitely recommend MDC and appreciate their professionalism, particularly the help from Moishy.
