There can be little doubt
that much of the modern superstition regarding the supposed unlucky
quality of the opal owes its origin to a careless reading of Sir Walter
Scott's novel "Anne of Geierstein". The wonderful tale contains nothing
to indicate that Scott really meant to represent opal as unlucky. Scott
used an opal to reflect brilliantly the changing fortunes of the
heroine but this was unappreciated by a world of literary flunkies, who
in their own minds conjured up the idea that the opal could have
properties of evil influence, the result was remarkably absurd. Twelve
months after the publication of Scott's novel, opal was down to half
its former high value and falling rapidly out of fashion, such was the
superstition that opal is unlucky.
