Diamonds are sold by the carat (shown as ct.), which is actually a unit of weight, though most think of a carat in terms of size. The word "carat" comes from the "carob" seed, the original unit of measure for diamond traders. Today, a carat is equal to exactly 0.2 grams (about the weight of a paper clip). Carat weight is unrelated to the similar sounding karat, which refers to gold's purity.
Reference only. True diamond size may vary based on monitor size.
Clarity Grade: I1
Inclusions are obvious under 10x magnification and may affect transparency and brilliance. I1 diamonds have inclusions that are almost always visible to the naked eye. Because I2-I3 diamonds have prounounced inclusions, and in the case of I3 may even affect the diamond's durability, they are not offered by Lumera.
Diamonds with color grading G, H, I, J in the GIA scale are near colorless diamonds. G-H diamonds contains only minor traces of color almost invisible to an untrained eye. I-J diamonds contain slightly detectable color to the naked eye. The near-colorless diamonds are the most commonly available colorless diamonds in the market.
