What is the difference between Fire and Brilliance in a diamond?
Fire is the coloured light reflected from within a diamond. White light entering a stone is separated into the many colours of the rainbow just like a prism. Good fire can only be achieved with very good to excellent proportions when cut. Brilliance is when white light is reflected up through the top of a diamond. Cutting a diamond to the correct proportions increases the reflection of light from the facets and maximizes the brilliance.
