Diamond Polish

The term "polish" refers to the overall condition of the surfaces of a finished diamond. A rating is assigned based on the amount of polishing lines that are visible. These polishing lines are caused by very small diamond crystals which are embedded in the polishing wheels used by diamond cutters to polish the surface of the diamond after cutting. Diamond polish is important because it can affect the degree to which light is able to pass through a diamond, rendering it more or less brilliant. Diamonds that are laboratory certified with a good, very good, or excellent polish rating are the most desirable. Diamonds that have poor polish will be less brilliant and not as desirable or valuable. Anjolee Signature Diamond™ are graded after examining the diamond facet by facet. They are then assigned one of these five polish ratings:

(EX) Excellent Not visibleAnjolee Signature Diamonds
(VG) Very GoodNot visible to unaided eyeAnjolee Signature Diamonds
(G) GoodMay be visible to unaided eye Not carried by Anjolee
(F) Fair Visible to unaided eye Not carried by Anjolee
(P) Poor Visible to unaided eye Not carried by Anjolee

To the unaided eye, 'excellent' and 'very good' ratings are hard to decipher. The differences become visible only when a stone is magnified. A rating of 'fair' or 'poor' means that the flaws in the polish are noticeable to the unaided eye and will have some effect on the overall beauty of the diamond.

The polish grading is included on the Anjolee Signature Diamond™ Certificate of Authenticity.

Poorly polished facets may reduce the intensity of a diamond’s reflected light or light which is refracted into and out of a diamond. This can affect the brilliance and visual performance of diamond. When a diamond has a 'good' or lower polish grading, the stone may appear as if it needs to be cleaned.
