Most diamonds are cut to achieve two goals: first, to yield the maximum weight of the rough diamond, and second, to achieve the most beautiful diamond. Your Lux Diamond is cut with perfection and beauty as its ultimate goal, sacrificing more raw material to produce the final diamond. This, coupled with the attention to symmetry, proportion, and polish, accounts for why your Lux Diamond costs more than a similarly sized diamond. There is a price for perfection!

Laser inscribed on the girdle of your Lux Diamond will be the diamond weight, the Lux logo, and the term H&A (Hearts & Arrows) in addition to the GIA grading report number.

A true ideal diamond makes up a very small percentage of the thousands of diamonds cut every year. For every million diamonds mined, only one will meet high enough standards to become a Lux Bond & Green true ideal diamond. An "ideal diamond" is a term used to describe a diamond that has been cut to meet exact standards of proportions, symmetry, and polish. The proper combination of these factors maximizes the amount of light that enters the diamond and minimizes the light lost from its sides and bottom. This efficiency produces an exceptionally beautiful and brilliant diamond.

Fluorescence describes the illumination created when a diamond is exposed to ultraviolet light. Faint of medium fluorescence rarely affects a diamond's appearance, but stronger fluorescence may have an impact on the perceived color. For instance, with a yellowish diamond with a strong blue fluorescence, the fluorescence can be strong enough to mask the yellowish tint when viewed under fluorescent lighting. When looked at under different lighting, that same diamond can look very different. Also, the opposite is possible as well - diamonds that fluoresce yellow may look more yellow under ultraviolet lighting, and whiter under incandescent lighting.

Symmetry is the grading term used to describe the exactness of the shape and placement of facets on a diamond. There are many variations that affect the symmetry of a stone, including off-center culets and tables, poor facet alignment, misshapen facets, and non symmetrical girdles. With poor symmetry refraction (the bending of light) can be misdirected as it enters and exits the diamond, causing a decrease in the scintillation (sparkle) of the stone. Symmetry also plays an important role in displaying Hearts & Arrows. Without excellent symmetry, a diamond would be unable to display Hearts & Arrows due to the shape or location of the facets. Also, even with excellent or ideal symmetry, it does not necessarily mean the stone does in fact display Hearts & Arrows. Symmetry is graded as: Excellent, Very Good, Good, Fair, or Poor, for stones graded by the Gemological Institute of America (GIA), and for stones graded by the American Gem Society (AGS), Ideal is also one of the grades, added above Excellent
