Gem-Grade Australian Opals
Gem is the grade we reserve for stones whose brightness and pattern put them above A$2,000 per carat — the material that makes an heirloom rather than an ornament.
Per-carat price is the great leveller in opal: a small stone of blazing fire can outrank a large dull one many times over. Our buying guide explains how brightness, pattern and body tone set value.
