BRIGHTNESS
Brightness helps us grade our opals. The brighter and more intense the colour the rarer and more desirable it becomes.
THE BRIGHTNESS SCALE
FROM SUBTLE TO DAZZLING
Brightness is graded from B1 (the least bright) to B5 (the brightest), with each step revealing more life and sparkle in the stone.
