There are many gorgeous diamonds in the world today, but one in particular stopped us in our tracks: The MSID.
The MSID diamond scores the highest marks possible for brilliance, fire and scintillation. The unparalleled brightness and beauty of the MSID is a result of unique cutting angles, and in fact is so unique that the U.S. Government awarded the diamond a patent. What is also amazing is that the MSID has the appearance of being 12 – 15% larger than a traditionally cut diamond of equal weight. The benefit to you? You get a magnificent diamond for your engagement ring at an incredible value.
