Which stage should I use?


The majority of round brilliant diamonds will be best viewed on the glass stage. They should be placed table down for best results. Please note, if the inscription appears upside-down, use the Image Flip button on the GIA App screen or the GIA Match iD LCD screen to rotate the image to the proper orientation.
