Diamond Anatomy - Explanation 
 Diameter – Width of the diamond as measured thru the girdle 
 Table – Largest facet of a gemstone 
 Crown – Portion of the diamond extending from girdle to table 
 Girdle – Intersection of Crown & Pavilion.  Defines Perimeter of Diamond 
 Pavilion – Bottom portion of the gemstone extending from girdle to culet 
 Culet – The Facet at the tip of the gemstone.  Preferred culet is not visible with unaided eye (“none” or “small”) 
 Depth – Height of Gemstone from Culet to Table 
 Crown Angle – angle of the Bezel Facet relative to the table plane 
 Pavilion Angle – angle of the main facet plane with respect to the table plane 

 The presence of absence of the culet make the diamond either a 58 or 57 faceted  
 one.  There are differing points of view of whether a diamond needs a culet.  Some  
 people say that the absence of a culet ensures that light stays within the diamond.   
 Other says that the culet being a “point” leaves the diamond susceptible to  
 breakage because the culet is the most delicate part of the diamond
