Interesting Diamonds facts

Symmetry

When a faceted diamond is observed under normal lOx magnification one can easily study the symmetry aspects of the cut. Today the symmetry of a faceted diamond plays a substantial role in the cut evaluation of diamonds.

There are certain factors that have to be checked for the perfect cut grade and these are:

1. Symmetry of the sides of the table edges

Symmetry of table and table edgesThe table facet of the round brilliant cut should form a perfect octagonal shape, sometimes one or more blunt table edges are observed. There should be four sets of parallel sides of the octagonal shaped table. When the edges are not straight, but are wavy then a good symmetrical cut is ruled out.

2. Centricity and parallelism of table

Excentric tableThe table facet has to be parallel to the girdle plane so that the crown height is equal in all directions. Many a time the table is tilted to remove some inclusion near the surface of the table. The octagonal shape of the table should have its centre exactly above the culet, otherwise it is called eccentric. An eccentric table creates different sizes of crown facets which affects the brilliance of the diamond.

3. Centricity of the culet

Excentric culetThe fine point or the smallest facet at the base of the brilliant cut is the culet. Sometimes the culet is faceted. This culet should lie in the centre of the octagonal table. It is very easy to see whether the culet is eccentric from a side view of the stone as well as on looking through the table. If the culet is eccentric then it indicates that the pavilion facet angles are unequal. This gives a very adverse effect on the reflection of light symmetry.

4. Sharpness in the intersection of the facet edges

Truncated facetsIn a perfect cut the edges of individual facets must meet in a single intersection without any truncated ends. Truncated facets do not meet at a point and affect the uniformity of the cut. Thus a truncated main facet when observed through the table interrupts the symmetrical effect of the adjoining facets.

5. Alignment of the crown and the pavilion facets

Displacements of the crown and pavilon facetsThe kite facets of the crown should exactly intersect with the pointed edge of the pavilion main facet and the upper girdle facet should synchronise with t\\t \owcv girdYe facets. There should be a perfect alignment and no sideways displacement with respect to each other. As this clearly affects the regularity of the cut and gives rise to uneven girdle as well as reduced brilliance.
