Brightness - One of the most important way to determine value of an Opal are three brightness ratings - Subduued, Bright, and Brilliant. Thess categories are broad and are a general indication of stone brilliance. Subdued is the least brightness - (But stillcan  be a beatifull stone).  Bright, meanes the stone has good level of brillance in the middle catigory. Brilliant meanes the stone has rxellent brightness and falles into the top catigory. Brilliant is obviously the most sought after gem grade and valuable property. 

Brightness of Fire
The other criterion is the brightness of the fire. Brightness is graded on a scale of 1 to 5.

Level: Name: Description:
1 Faint Shows a little play of color only under direct sunlight, none under low light
2 Dull Shows some color under low light, but is dull even under indirect sunlight
3 Bright Shows fair color under low light and very nice fire under indirect sunlight
4 Very Bright Shows good color under low light and sharp crisp color under indirect sunlight
5 Brilliant Shows exceptionally bright crisp color in all lighting situations
