Editing Diamond (section)

=== Clarity ===
Clarity is one of the 4C's (color, clarity, cut and carat weight) that helps in identifying the quality of diamonds. The [[Gemological Institute of America]] (GIA) developed 11 clarity scales to decide the quality of a diamond for its sale value. The GIA clarity scale spans from Flawless (FL) to included (I) having internally flawless (IF), very, very slightly included (VVS), very slightly included (VS) and slightly included (SI) in between. Impurities in natural diamonds are due to the presence of natural minerals and oxides. The clarity scale grades the diamond based on the color, size, location of impurity and quantity of clarity visible under 10x magnification.<ref>{{cite journal | vauthors = Cowing MD |year=2014 |title=Objective ciamond clarity grading |journal=Journal of Gemmology |volume=34 |number=4 |pages=316–332 |doi=10.15506/JoG.2014.34.4.316 |bibcode=2014JGem...34..316C |url=https://acagemlab.com/wp-content/uploads/2019/01/JoG2014_34_4_Cowing_Obj_Diamond_Clarity-1.pdf |archive-url=https://web.archive.org/web/20210418052002/https://acagemlab.com/wp-content/uploads/2019/01/JoG2014_34_4_Cowing_Obj_Diamond_Clarity-1.pdf |archive-date=April 18, 2021 |url-status=live |access-date=September 19, 2021}}</ref> Inclusions in diamond can be extracted by optical methods. The process is to take pre-enhancement images, identifying the inclusion removal part and finally removing the diamond facets and noises.<ref>{{cite journal | vauthors = Wang W, Cai L | title = Inclusion extraction from diamond clarity images based on the analysis of diamond optical properties | journal = Optics Express | volume = 27 | issue = 19 | pages = 27242–27255 | date = September 2019 | pmid = 31674589 | doi = 10.1364/OE.27.027242 | bibcode = 2019OExpr..2727242W | s2cid = 203141270 | doi-access = free }}</ref>
