Diamonds are very valuable, they are nature's hardest substance. When grading diamonds there are the 4 C's: Color, Cut, Clarity, and Carat (weight, ctw). The diamonds we use are SI-SI2 Clarity, G-H Color, Round brilliant cut, and either 6 point or .06 carat for the solitaires, and 4 point or .04 carat for the multiple stone set rings. The diamonds used for our tungsten jewelry are conflict free, and are ethically made precision stone set right here in America. Our solitaire diamond rings are set with a 14K white gold bezel that helps keep the diamond set into the ring, the other rings with more than one diamond are set in the precious metal listed that is also the inlay, such as platinum, palladium, or silver. Most natural diamonds are formed at high-pressure high-temperature conditions existing at depths of 140 to 190 kilometers (87 to 120 mi) in the Earth mantle. Carbon-containing minerals provide the carbon source, and the growth occurs over periods from 1 billion to 3.3 billion years, which respectively corresponds to roughly 25% and 75% of the age of the Earth.
