Mookaite

Mookaite properties at a glance

Geology & background

Forms as silicified radiolarite or jasper-like sedimentary material, with iron-rich impurities creating warm red, yellow, cream, and purple colors.

Mookaite is a modern lapidary trade material tied closely to Western Australian specimen and jewelry markets.

How to identify Mookaite

• Look for opaque patches of mustard yellow, red, cream, brown, or purple.
• Mookaite is usually massive and jasper-like rather than transparent or crystalline.
• Western Australian provenance supports the identification, but color pattern alone can overlap with other jaspers.

Where Mookaite is found

Mookaite is most strongly associated with Western Australia; verify locality when provenance matters.

How much is Mookaite worth?
