potch

1982, Gemmological Association of Great Britain, The Journal of Gemmology, Volume 18, page 432,
Discusses the difference between potch opal and common opal. The terms are often used synonymously, but this writer shows that potch is found only in association with precious opal and differs from common opal in its structure quite substantially.

She set them down with precision, she set them down with the same kind of care that Bernie took when he and his underlings cut opal, or when they polished the rough stones, or when they bonded opal veneer on to potch.

1996, Janette Turner Hospital, Oyster, paperback edition, Virago Press, page 75:

2006, Michael O'Donoghue, Gems: Their Sources, Descriptions and Identification, 6th Edition, Elsevier, UK, page 321,
Likewise, a thin piece of good opal on potch (opal with no play of colour) may be cut so that the potch acts as a backing.

(chiefly Australia, mineralogy, gemmology) A type of rough opal without colour, and therefore not worth selling.
