Black inclusions are black crystals contained within a diamond, and due to their high visibility are considered less desirable. Though not listed on most diamond certificates, nor disclosed by most retailers, it is standard practice within the diamond industry to disclose and evaluate diamonds depending on the degree and severity of black inclusions.
Symmetry refers to the arrangement and even placement of a diamond’s facets. A symmetrical facet arrangement maximizes beauty and minimizes the potential for light loss.
Diamond treatments and synthetics are increasingly being passed off as natural diamonds. Common gemological equipment can no longer detect all treatments or synthetics. Therefore only gemological institutes with advanced equipment can certify that your diamond is 100% natural and untreated.
