The report provides details about the cut, clarity, and carat weight, along with measurements and other additional information confirming the authenticity and quality of the diamond.
You can select from a variety of diamond shapes and cuts (brilliant, pear, marquise, princess, oval, etc.).
The GIA grades diamonds on a scale of D (colorless) through Z (light color). The diamonds we select for our designs correspond to colors G or F, which means that they are nearly colorless and only a professional gemologist can detect the difference between colors.
Practically all natural diamonds contain small imperfections inside, called inclusions, or on its surface, called blemishes. Clarity refers to the degree to which these imperfections are present. On the scale from included to flawless diamonds, the diamonds in our designs are graded as VS or VVS, which stands for “very slightly” or “very, very slightly included”. Inclusions are minor and only visible under a magnifying glass and not to the naked eye.
