Reading Diamond Certs :: Symmetry
Symmetry is one of two aspects of the Finish of a diamond ::
We consider Symmetry very important in the making of a beautiful diamond. Poor facet alignment will allow light to leak out before it reflects back to your eye — resulting in less brilliance and fire.Without symmetry, the facets will not line up at the best angles and matching for maximum light performance.
In fancy shaped diamonds, such as a heart shape, poor symmetry may cause one side to be broader than the other and give it a lop-sided appearance, or result in uneven facet arrangements, both of which can also allow light to leak.
Grades for symmetry range from::
- Ideal (which is very rare)
- Very Good
We consider Good symmetry to be the minimum for a diamond used for an engagement ring.
