The term "Finish" specifically refers to the overall quality of the polish and the precision of the cut in a fashioned gemstone. It encompasses how well the surface of the gemstone has been polished and whether the facets are correctly aligned and shaped, impacting the stone's ability to reflect and refract light effectively. A high-quality finish contributes to the gemstone's overall visual appeal, enhancing its brilliance and aesthetic qualities.

In contrast, "Brilliance" focuses on the amount of light that returns to the viewer's eye from the gemstone, which is influenced by the quality of the cut but not solely dependent on the polish. "Cut Quality" involves a more comprehensive assessment that includes factors like proportions and symmetry, along with polish. "Clarity" refers to the presence of inclusions or blemishes within the gemstone, which affects its transparency and overall appearance but does not relate to the cut or polish itself.
