The etymology of the term "opal" is derived from the Roman word "opalus,” which translates to "to see change of color.” During the Middle Ages, opal was thought to bestow good luck upon its wearer. This belief underwent a transformation in the early 1800s after the release of a story about a magical princess whose opal would change hues based on her feelings.

Tragically, a few drops of holy water extinguished the stone's enchanting fire, resulting in the princess's death. The discovery of opal deposits in Australia post-1850 rejuvenated the gemstone's image, as the nation began to provide 95 percent of the global opal supply along with many of its most exquisite specimens. The decreasing availability of traditional opal in Australia has
impacted the market value of this distinctly vibrant gemstone, which continues to be highly sought after due to its capacity to mirror a range of emotions and tastes.

Opals may be subjected to enhancements such as oil and
resin impregnation, dyeing, and surface treatments including smoking or sugar treatment. Natural, untreated opals typically fetch higher prices and are perceived as rarer compared to enhanced opals. Aspects such as color, pattern, clarity, size, and body tone play a significant role in determining an opal's value, with vibrant colors, unique patterns, and high clarity being particularly sought after. When it comes to cleaning opals, it is crucial to steer clear of harsh chemicals, extreme temperatures, and physical impacts. To
clean opals, use warm, soapy water along with a soft cloth, and store them in a padded cloth bag or a humid environment to avoid dehydration.
