Surface polishes

All, A mix of polished versus matte surfaces creates very interesting
effects both in gemstones and metals. In manufacture of gemstones and
metal an aesthetic balance is achieved between matte and polished
surfaces to either enhance the beauty or hide defects. Abraded
surfaces do nothing to enhance the appearance of either. Thus I
agree that the ability of a material to hold the polish or the matte,
is far superior to a material that will not.
