An example of the effects of such light is blue fluorescing diamonds. Diamonds which fluoresce blue in UV light may have a yellow tint to them in UV free white light which is cancelled by the blue fluorescence in (daylight) conditions.... (1994) Complete Story

Leather however remains tried and true as material for making mallets from.... (2004) Complete Story
