Cowell jade exhibits a variety of colours and textures, but consists predominantly of medium to fine-grained material showing grey to dark green hues, lensing to dense black. Three main varieties are marketed — green nephrite, black nephrite and premium black nephrite. Grades and pricing are determined by density (specific gravity) and colour. 

Premium Cowell Black Jade achieves a mirror polish by simple lapidary techniques. All Cowell Jade will polish at 8000 grit.

 As with all Jade deposits, some deposits exhibit spectacular patterns, dendritic inclusions, and wavy banding on the rind of near-surface boulders. Patterns vary in colour from Pale Whites to Light Grey and Olivine in colour.
