A Symmetry of diamond shows how various cut/shape diamond will be valuable. Refer this file for topics covered in diamond symmetry for grading of diamond.
E N D
Research of table, culet, girdle, facet, pavilion in diamond. • Check for alignment of cuts. • When You purchase a Certified diamond you will get certification report of it. • Poor symmetry diamond may not good for jewelry. What is Symmetry in Diamond?
It is possibility that a diamond can have following defects in it, Which affects its quality and genuineness. • Off-center table • Misshapen facets • Out-of-round girdle outline • Off-center culet • Wavy girdle • Crown & Pavilion misalignment Defects of Diamonds
For diamond grading , A light is passed from top of it. If light straight reflect to eye then it is very good symmetry diamond. • Misplacing in diamond shaping, creates light skipping. • Diamond certification laboratory check for these several defects to grade a diamond to one of ’Excellent’, ‘Very Good’, ‘Good’, ‘Fair’, and ‘Poor’ Symmetry . Grade ofSymmetry
Excellent symmetry diamond means not any misplacement. • Reflects Light in straight 4 times more when passed in it. • Rare to find. Excellent Symmetry
Reflects light from other side of top. • Contains a very slight misalignment which is not recognizable. • Low reflection compared to ‘EXCELLENT’ • Useful for low cost purchase. Very Good Symmetry
Contains few misalignments. • Low reflection than ’Excellent’, ‘Very Good’, Diamonds. • Costs less. • May Contain missing facet. Good Symmetry
80 % of people don’t choose this grade symmetry. • We can see some Misplacement by naked eye. • Light reflection is not proper and can skip also. Fair Symmetry
Thick Girdle, Light could not enter into diamond. • Light skips in unwanted manner. • Lots of defects, misalignments. • Not recommended. Poor Symmetry
