Diamonds Symmetry Ouros Jewels
What is Symmetry of Diamond? • Grading of diamonds facet, table, culet, girdle, crown, pavilion’s alignment. • How facets and angles of diamonds are symmetrical. • Check if table’s culet centered, Size and shape of all facets uniform • When You buy Certified diamond you will get certification report of it. • Poor symmetry diamond will not good for valuable jewelry.
Diamond Symmetry defects • Off-center culet • Off-center table • Misshapen facets • Out-of-round girdle outline • Crown & Pavilion misalignment • Wavy girdle
Off-Center Culet Diamonds bottom point is not exactly in middle.
Off-center table Top of table’s facet is not perfectly centered.
Miss-shapen Facets Pattern is not symmetrical. Triangular shaped facets are not in same order.
Out of roundgirdle outline When a round cut diamond is shaped improperly.
Misalignment of Crown and Pavilion Crown and pavilion facets should be aligned at girdle points.
Wavy Girdle The girdle of diamond is not in straight line around it.
Symmetry Grade • To check diamonds genuineness, A light is passed from top of it. If light straight reflect to eye then it is very good quality diamond. • Because of defects in diamond shaping, light passes from top and skips through bottom or side .this doesn’t make value. • Diamond certification laboratory check for these several defects to grade a diamond to one of ’Excellent’, ‘Very Good’, ‘Good’, ‘Fair’, and ‘Poor’ Symmetry .
Excellent Symmetry • Excellent symmetry diamond does not contain any defects. • Rare to find. • Reflects Light in straight 4 times more.
Very Good Symmetry • Contains a very slight misalignment • Reflects light from other way of top. • Low reflection compared to ‘EXCELLENT’ • Useful in tight budget.
Good Symmetry • Contains few misalignments. • Low reflection than ’Excellent’, ‘Very Good’, Diamonds. • May Contain missing facet. • Costs less.
Fair Symmetry • We and 80 % of people don’t choose this grade symmetry. • At Least ‘Good’ symmetry diamond is recommended. • We can see some Defects by naked eye. • Light reflection is not proper
Poor Symmetry • Thick Girdle, Light could not enter into diamond. • Light skips in unwanted manner. • Lots of defects, misalignments. • Not recommended.
