A 10-Point Plan for Diamonds (Without Being Overwhelmed)

Finding the Right Diamond Cut Grade Cut grade is the key factor in determining the total form of a diamond since a defectively cut diamond will seem dull even with great clarity and color. On the other hand, a well cut diamond can have a somewhat lower color (G-H) or clarity (SI1-SI2) and still look fairly gorgeous, because of its outstanding ability to sparkle. Cut grade provides a single rating which integrates a diversity of factors, making it an uncomplicated yet critical tool in appraising a diamond. A familiar mistake is to consider these specific factors instead of trusting principally the Cut grade, which already takes all of them into light. Only when two diamonds of the same Cut grade are compared should the individual aspects of Cut apply to refine your search further. That said, below are these individual factors and some tips: Culet
Lessons Learned from Years with Diamonds
Any Medium culet size or smaller will be imperceptible to the naked eye, and make no negative impact on the look of a diamond.

Girdle An Extremely Thin girdle is more predisposed to chipping, and hence ought to be avoided if the diamonds are intended to be set in a ring. Earrings or pendants are not as exposed to rough contact and thus are not as likely to chip around the girdle too. Even Very Thin girdles in Princess Cut diamonds should be avoided, as this shape already comes with sharp corners that make chipping more probable. If you do get a Princess Cut diamond with a Very Thin girdle, set it in a design where the corners are protected. Polish For diamonds whose polish grade is Excellent to Good, any polishing flaws will not be noticeable to the naked eye, nor make an impact on the gem’s total appearance. For diamonds having clarity grades of 1 or less, even a polish grade of Fair is satisfactory, given that these diamonds already keep internal inclusions that are detectible to the naked eye, reducing the relevance of any polish markings . For diamonds lower than . Poor is the only polish grade that must be avoided irrespective of the clarity or size of the diamond. Symmetry For diamonds that have a symmetry grade of Excellent to Good, symmetry is not to be used as a main factor in selecting them, because each of these grades can be expected of diamonds of excellent appearance. Symmetry is more crucial in diamonds with VVS2 Clarity and higher, as the very refined defects coming from Fair or Poor symmetry (which can look a lot like pinpoint inclusions), would impede the diamond’s otherwise unblemished appearance. In spite of its fair effect on appearance, symmetry has a sizable impact on price; a diamond with Excellent Symmetry and Polish could cost 10%-15% more than a diamond having Good Symmetry and Polish. Finally, as diamonds with Poor symmetry have imperfections that are visible to the naked eye, they must be avoided completely.
