Are these moissanite?
No. We do not sell moissanite or diamond simulants. Every stone we set is a genuine lab-grown diamond

About Measurement Methods
How do I find the right size?
For the most reliable result, have the intended finger measured by a jeweler with a physical ring sizer. You can also compare the inside diameter of a well-fitting ring with our Ring Size Guide. At-home measurements are estimates; contact us before ordering if you are unsure.
