MDC Diamonds NYC Custom Jewelers:
Let Us Make Your Dreams Come True:

We offer handmade models as well as CAD (computer-aided design) models, depending on which will provide you with the best results for your design. Whether a new model is needed, from a matching wedding band or an engagement ring or using an existing style but with different diamond specifications, our highly trained staff will be able to produce just what you seek.
Typically, delivery time for a fully finished piece of jewelry requiring a new model is 21-28 business days. ( Can be rushed if necessary )
Our model charges start at $350. Before we start making your model, we will inform you of the approximate price which you will be charged.

When you order an adjusted style from MDC Diamonds, our custom piece of fine jewelry is manufactured to your specifications.
