Cut describes the workmanship and design of turning a “raw” diamond crystal into a vibrant gem. Diamond cutters make choices when they plan and execute how a raw diamond’s cut will interact with light. There is not a single “top-grade” way a diamond can be cut that everyone prefers. This solely relies on your taste and what pleases your eye; you may prefer a diamond with a cut grade of Very Good to one graded Excellent.
Once you know the words that describe what a diamond does with light then you will be able to see each cut characteristic for yourself. How a diamond is cut, or designed, determines its Brightness, Fire and Sparkle.
Brightness, sometimes called brilliance, is the level of light that radiates up from within the diamond. Light bends when passing through diamonds, because they are so dense. If a diamond is cut with a proper silhouette, a light ray will make a “U-turn” when passing through it, returning a shower of brightness and fire back toward the eye. Without a proper silhouette, the light will fail to complete the U-turn, resulting in less brightness and less of the rainbow-like fire.
Key to creating the proper silhouette is weight-ratio: the relationship between the diamond’s size (viewed from the top) and its weight. Almost all raw diamonds have a silhouette that is too deep; their underbelly “fat” needs to be removed to steer light in a desirable U-turn.
Devotion diamonds come with a unique brightness grade that will help you determine what cut design you most prefer.
Fire, sometimes called dispersion, describes the colors of a rainbow that appear in a diamond. As a diamond moves, the shards of colors change like a kaleidoscope, so it’s best to see fire in different lighting conditions and from different viewing angles. It is also best to view the diamond from a distance of over three feet because when viewed from up close, the shards of color change to shards of white light.
Each Devotion diamond comes with its unique fire grade that will help you determine what cut design you most prefer. That’s why your personal taste plays an important role in selecting the perfect diamond along with guidance from a diamond expert.
Sparkle, often called scintillation, describes the sparkling or twinkling effect given off as diamonds move. These flashes of mini-fireworks are produced by light rays reflecting off the diamond’s many surfaces. Your eyes perceive the flashes if there is sufficient contrast within the diamond. These mini-flashes are more beautiful than one big blast, which would appear “washed out” like a blaring headlight. The pattern of sparkle is also important, so that you see an evenly spread out field of “stars” rather than a blotchy array.
Symmetry describes the alignment of the many surfaces on a diamond, called facets. Diamonds that are perfectly aligned appear more beautiful to us. Creating excellent symmetry takes great time, care, planning and attention to detail.
Trust your eye and your judgment. While the GIA symmetry grades are Excellent, Very Good, Good, Fair and Poor, don’t immediately pass on a diamond with a lower grade. There can be symmetry “deductions” that are visible under a microscope that do not affect the visual beauty of the diamond.
Polish, also called “finish,” describes the quality of a diamond’s surface. Due to a diamond’s extreme hardness, creating a mirror-like finish on each surface (facet) can only be achieved after long and painstaking grinding then polishing. In an improperly polished diamond, telltale parallel or circular lines will interfere with the luster, or “pop,” that comes from light reflecting off its surfaces.
The individual surfaces must join invisibly, with seamless edges, so that the diamond appears as a singular, solid entity. Finish is important but a grade of Very Good (rather than Excellent) may result from “deductions” that are visible under a microscope but do not affect the visual beauty of the diamond.
The definition of a diamond’s “hardness” is its resistance to scratching. It is important to cut a diamond so that its outer edge, called its girdle, is not too thin. Equally important is the tiny facet called the “culet,” on the very bottom of the diamond, which is important to prevent breaking or chipping.
The corners of some of the fancy shaped diamonds have “points” which can be damaged when being set. Devotion’s patented modified square-cut Devotion design eliminates this problem on both the point and corners of the diamond.
A weaker crystal structure will make a diamond appear as a dull, oily or grayish. In this case, a diamond can have a respectable grade but will be missing “the bling.” Devotion selects diamond types from “sawable” material: well-formed unpolished crystals that have a different crystal structure than most all other diamonds, producing a vibrant, powerfully brilliant stone. Every Devotion center diamond is hand-selected, ensuring that the crystal structure is indeed beautiful.
