Liquid or molten metals were added to the glass during manufacture to produce the changing opal-like coloration in the cabochon. 'Dragon's breath' stones reflect changing colors when moved or the light source changes. Those reflected colors include primarily red to blue with more subtle colors including yellow, orange, green, bright blue or purple..." by R. Keith Golden
