Great Price For This Color and Size Unheated Yellow Sapphire! Clean and crisp gem, nice face-up size and affordably priced! This sapphire has a "window" in the center. A window is an area of reduced brilliance due to a deviation in the proportions/cutting angles of the pavilion (bottom portion of the stone). The gem-cutter made this variation in order to improve the face-up size and to maximize the finished weight from the rough crystal. Some clients prefer a windowed gem because it can give a much bigger face-up dimension, relative to the carat weight. If you want to maximize the face-up size of your gem, this is your sapphire! Clarity: LI2. Certificate #CA92891509C

How Do We Know These Are Unheated Yellow Sapphires? |
Heat treatment of yellow sapphires modifies their internal structure.

Yellow Sapphire Clarity Grading: Yellow Sapphire clarity grades are assigned when a trained, experienced gemologist examines the gem "face-up" under controlled lighting without magnification. . Sapphire clarity grades are assigned without magnification. Sapphire clarity grades are determined by an inclusion's visibility, or lack of visibility, to the naked eye.. This is the procedure at the major Gem Labs. . This is in sharp contrast to diamond grading where 10X magnification is required. The top sapphire clarity grade at American Gemological Laboratory is "Free of Inclusion" . and the top sapphire clarity grade at Asian Institute of Gemological Sciences is "Flawless". . According to the Gemological Institute of America's Revised Colored Stone Grading Lab Manual, . the top clarity grade for sapphire is "Eye clean". . These grades are assigned when an experienced, fully-trained gem-grader is unable to see any inclusions under ideal lighting conditions and without magnification. . When examined under magnification, almost all sapphires show some natural inclusions, regardless. of whether these inclusions are visible to the naked eye. So, a sapphire that is honestly graded . "Flawless" or "Free of Inclusion" or "Eye-clean" almost certainly contains inclusions at some level of. magnification. (As do most Flawless diamonds!). 10X is the basis for diamond clarity grading. Naked-eye is the basis for sapphire clarity grading. Diamonds and sapphires almost always show natural inclusions if the magnification is high enough.

Proportion Grading Of Yellow Sapphires |
Good proportions in gems are found when the crown angles and pavilion angles. Proportions are more important in diamond grading.than in colored stone grading. Excellent proportions are essential to the beauty of a diamond. The entire visual impact of a diamond is created.by light rays reflected from its surface and refracted from within it.. In all colored stones (all gems other than diamonds),.color is a more important contributor.. The cutter of yellow sapphires saves as much weight from the rough . |
