Diamonds are the stone of choice for engagement rings and wedding jewelry. Diamonds are durable and remain a timeless way to complement every style.

Carat: Diamond carat weight is the measurement of how much the diamond weighs and is equivalent to 200 milligrams per carat. Each carat is subdivided into 100 points. Therefore, a one-carat diamond is 1.00 or 100 points, while a twenty-five point diamond is .25 carats. Naturally, larger diamonds can be more rare and desirable.

Color: A white diamond is more valuable the less color it contains. GIA uses a D-to-Z grading system to determine a diamond’s color value. D would be a colorless diamond and Z the most saturated with color.

Clarity: Diamonds are formed by carbon exposed to heat and pressure. Natural internal characteristics known as inclusions and external components called blemishes are the norm. The closer the gem comes to being perfectly pure without inclusions or blemishes, the greater the value.

Cut: To transmit light and sparkle, diamonds have to be cut precisely and with great artistry. A diamond will be further graded based on symmetry and proportions, as well as how the stone returns light. Brightness, which is the internal and external white light reflected; fire, or the scattering of white light into rainbow colors; and scintillation, or the sparkle the diamond produces, are factored into how the cut is valued.

Diamonds are a major investment. Consumers who do their research and verify diamond grading can get the best value for their money.
