Miami Engagement Rings. Buying a diamond can be a complex process and costly if not properly informed. DVG Diamonds offers consultations with customers geared at educating them on all the different properties and cost variations when purchasing a diamond. Once a customer has selected the diamond of their choice, we then begin the process of ring fabrication designed specifically for their Miami engagement ring. Whether you are ready to purchase or not, please come by for a free consultation prior to making any decisions on your Miami engagement ring. We also have in stock a large selection of stunning GIA diamonds in our downtown Miami location.
