Transparency, or the appearance of the gemstone, is also a critical factor, with crystal opals being highly valuable.
Clarity, or the presence of internal flaws or inclusions, is related to the quality of the gemstone. Inclusions, such as cracks or fractures, can significantly affect the opal’s value. Size, type, and origin also influence the value of the opal.
The cut and shape of the opal also affect its value, with well-proportioned and expertly cut opals being more valuable. The setting and jewelry design also contribute to the overall value.
How To Care For Opal Jewelry
Opals are delicate gemstones with a hardness rating of 5.5 to 6.5 on the Mohs scale, making them more susceptible to damage.
They are sensitive to heat and chemicals, so exposure to household cleaners, perfumes, and cosmetics should be avoided.
To protect opals, avoid wearing them during physical activities, remove them before swimming or bathing, and store them separately from other jewelry.
Safe cleaning methods include gentle cleaning with a soft cloth, mild soap, and lukewarm water, and avoiding ultrasonic cleaners and steam cleaners.
Store opal jewelry in a cool, dry place away from direct sunlight and extreme temperature fluctuations, and use a soft pouch or jewelry box with compartments.
Professional jewelers should examine opal jewelry periodically for loose settings, damaged prongs, or signs of wear.

Conclusion
Opal formation is a mysterious process that involves the alignment of molecules in a gel. It is a hydrated amorphous form of silica, classified as a mineraloid.
The ingredients for forming opals are commonplace, with water in the ground carrying dissolved silica seeping through beds of sand and grit.
As the water evaporates, the silica particles form a gel that hardens as the cells become “cemented” together.
The gemstone is created when hydrated silica fills holes formed by foreign elements, such as squid bone or shell.
This process is rare, making it difficult for miners to find opalized fossils, or Belemnite.
Fossilized opal shells are rare, occurring when inland seas recede.
In rare occurrences, hydrated silica forms a diffraction grating, producing colors like red, orange, yellow, green, blue, indigo, or violet.
These rare opals are highly valuable and make exceptional jewelry for collectors.
Today, we can admire the beauty and fire of opals and opalized bones.
