Is a lab-grown diamond a real diamond?

Yes. Lab-grown diamonds have the same carbon crystal structure and optical properties as mined diamonds. They are graded on the same clarity, color and cut scales, so VVS1 and D mean the same thing here.

What do VVS1 and D mean?

VVS1 means very, very slightly included: flaws are so small they are hard to see even under 10x magnification. D is the top colorless grade. Together they put the stones near the top of the scale.

Can this band be resized?

A continuous diamond band usually cannot be resized without interrupting the stone line. Ask about sizing before you buy, and consider a half-eternity design if you expect finger size changes.

How does it compare with a mined-diamond tennis band?

The look and wear are essentially the same. Lab-grown stones usually cost less for the same carat weight and grade, but they resell for much less than mined diamonds.

How should I care for it?

Clean it regularly with mild soap, warm water and a soft brush to keep the stones bright. Have the settings checked by a jeweler once a year, since tennis bands lose stones when prongs loosen.
