How much is an opal worth?
1 Answer
An opal's value is determined based on a set of characteristics. Namely, the type of opal, body tone, brilliance, pattern, color bar thickness, play of color, and faults are taken into account by an appraiser when determining the value of the stone. Typically, black or dark bodied opals are regarded as more valuable than those with a light body tone.
