Triple X Diamonds
Triple X Diamonds
Triple X diamond is a technical term that refers to stones that have excellent cut, polish and symmetry in their ratios.
The Triple X rating is very important and rare.
What is a Triple X Diamond
A “Triple X diamond” refers to brilliant-cut diamonds that have been graded as having excellent cut, excellent symmetry, and excellent polish. X is short for Excellent, so Triple X stands for Triple Excellent. A diamond’s grades of cut, symmetry, and polish indicate the quality of craftsmanship that goes into turning a rough diamond into a polished stone. These three factors affect how a diamond interacts with light. That’s why Triple Excellent diamonds are flawless diamonds.
Think of a diamond as a succession of tiny, angled mirrors, what gemologists call “facets.” A brilliant-cut diamond has 57 or 58 of them. These facets reflect light off of each other,
It’s an incredible light show that changes with the slightest movement, which is why light affects the appearance of a diamond. The characteristics of the facets, their angles, size and mutual arrangement, as well as the quality of their surfaces, indicate the quality of the diamond's cut and are essential to providing the diamond with the brilliance that is expected.
The factors that determine the 3 Xs
Cut
is the most important factor in a diamond. It determines the proportions of a diamond, its depth, and the angles of its facets, which in turn affect the way it reflects light. An excellent cut grade means that a diamond has been cut within parameters that allow the diamond to radiate intense brilliance, sparkle, and fire, while still having an even pattern of light and dark areas. Poorly cut diamonds often have large light or dark spots that make the stone appear dull or uninteresting to the eye.
Symmetry
is about the accuracy of a diamond’s shape. It refers to how well the facets are aligned, and how identical the same types of facets are in size, shape, and proportion. In a diamond with excellent symmetry, all the facets meet at the girdle (the widest part of the diamond). And the points of the kite-shaped facets on the crown (top of the diamond) align with the points of the wedge-shaped facets on the pavilion (bottom of the diamond). The large octagonal facet of the top table is centered, while the pavilion facets at the bottom meet in a perfect point at the tip of the diamond. Excellent symmetry improves the refraction of light in the diamond and makes it appear more harmonious.
Polish
The polish, or smoothness of the surface of a diamond, is the quality of the finish of a diamond. A diamond with an excellent polish will have no polishing defects visible under 10X magnification. Small surface defects, such as pits and polish lines, are often created by the polishing wheel during the polishing process and can usually be removed through re-polishing. Although they are often invisible to the naked eye, the fact that the diamond has surface defects will detract from the brilliance and sparkle of the stone. Think of the facets of the diamond as mirrors. The smoother the surface, the better the reflection. The diamond gathers light through these mirrors (facets) around the observer. When a diamond has the right proportions and symmetry, the mirrors reflect that light in a dazzling play of brightness, fire and sparkle.
