How is Opal Valued

Opal is one of the hardest gemstones to evaluate, because there are so many variables to take into account.  Some of these variables include:

It's important to note that the value of opals can fluctuate over time due to changes in market demand and availability, so prices can vary widely depending on current market conditions.  As well this calculator is only meant to give an estimate of the value of an opal and should not be taken as an appraisal, if you need an exact value for a stone we suggest finding a local gemologist or appraiser.
