Yes, real, natural opal—specifically hydrophane Ethiopian opal—can turn yellow, brown, or cloudy. This is due to its porous nature, which causes it to absorb water, oils, soaps, and chemicals like a sponge. While this discoloration is often temporary and reverses as the stone dries, constant exposure can lead to permanent damage.
"Hydrophane opals have the ability to absorb water or liquids, similar to a sponge, resulting in a change of color that may turn the opal translucent yellow or brown and the play-of-color to disappear temporarily. Don't panic though! The color will return once the opal is fully and naturally air-dried."
Real opals have natural variations in pattern, body tone, and backing. If you're examining a loose stone or jewelry piece, look for signs like a perfectly flat line between layers (a sign of a doublet), a glassy surface (often seen in triplets), or a flawless black backing (another indicator of a composite).
Exposure to extreme temperatures, prolonged direct sunlight, or low humidity can cause the Opal to dry out, leading to a loss of its vibrant colour play.
