Round diamond cutting in pictues

Cut - Scale

Not to be confused with shape, the cut scale applies to round diamonds only...PERIOD. Do not be fooled by fancy cuts with "Ideal Cuts", there is no such thing. All other factors equal, an excellent cut diamond will sparkle more than a poorly cut diamond.

Different shapes of diamonds

Cut - Shape

There are over 20 different shapes of diamonds if you include accent shapes. However, the ten most common are pictured left. Round has been, and will likely remain, the most popular. Thus, prices for rounds are slightly higher than all other shapes.

Diamond clarity grading pictures


The term used for grading internal and/or external flaws. The naturally occurring internal  varieties and naturally or accidental (i.e. chips) external varieties affect a diamond's value. Most important take away...there is a range within each clarity grade. Not all SI1's are created equal.

Diamond color grading pictures


Perhaps the easiest "C" to grasp; is the diamond white or yellow? But as in life, nothing is black and white. These are the 7 color grades that are considered to be a shade of colorless (DEF=colorless; GHIJ=near colorless)
