This historical significance and strong demand for opals contribute to their high monetary value in the market.
One piece of evidence that supports the inference that opals can be worth a lot of money is their rarity and limited supply. Opals are not as abundant as other gemstones, such as diamonds or rubies, making them relatively more precious. Additionally, the quality and uniqueness of opals, including their color patterns and play of light, contribute to their high value in the market.
