Pinfire pattern is exactly as described. Fine flashes of fire punctuate the stone as it moves.
Characterised by a pattern that radiates out from a centre nucleus. This is an uncommon pattern.
This pattern is mostly found in material from the Grawin Opal fields. It is characterised by soft feather like lines that fan out.
