Hints About quality loose diamonds
Dispersion is the splitting of white light into its spectral colours, as with light transmitted through a prism. It is also called fire when describing the dispersion seen in gemstones; diamond is a good example with a high dispersion value. Diamonds may be cut to increase dispersion at the sacrifice of brilliance or vice versa as described above in the brilliance description. The fire in opal is caused by the dispersion of light through its unique hydrous silica structure. The amount of dispersion in gemstones can be given in figures, but is generally described simply as low, medium and high.
