Cowell jade exhibits a variety of colours and textures, but consists predominantly of medium to fine-grained material showing greenish yellow to green hues, grading to black. Three main varieties are marketed — green nephrite, black nephrite and premium black nephrite. 


Cowell black jade takes a very high polish by simple lapidary techniques. Very fine-grained premium black takes a mirror-like polish.


 There are also rare varieties which exhibit spectacular patterns, including varieties with dendritic inclusions, and wavy banding on the rind of near-surface boulders. Which vary in colour from Pale Whites to Light Grey and Olivine in colour.
