A tool designed to estimate the worth of opals considers factors like type, body tone, brilliance, pattern, origin, and carat weight. For instance, a black opal with vivid play-of-color and minimal inclusions from Lightning Ridge, Australia, would likely receive a higher estimate than a common opal with a dull appearance.
Such an estimation tool provides a crucial starting point for both buyers and sellers, promoting transparency and informed decision-making in the opal market. Historically, opal valuation has been subjective and reliant on expert opinion. A more data-driven approach empowers individuals with knowledge, potentially leveling the playing field and ensuring fair pricing. This is particularly beneficial in online marketplaces where physical inspection is not always possible.
