If you don't mind a little photo advice....
For etched or engraved items, have your light source low and to the side so it creates a shadow in the engraved "trench" instead of illuminating it. Use a room lamp and disable the flash on your camera. Turn the other lights (ceiling lights) in the room down or off. All this will help the engraved text to stand out in sharper contrast and make it much easier to see and read.
