Diamonds Matched by Size and Color

Below are two of my best diamonds that are closely matched for size and color, plus a photo of the two diamonds side-by-side. They both are very clean unternally, have very pale yellow color, and each has excellent natural sparkle caused by the many complex crystal faces on the surfaces. These would make beautiful earrings or pairings on a wedding ring or could be part of a pendant. Must see in person to appreciate.
