opaler

Opaler is a term that can refer to several things, most commonly a type of opal or a process related to opals. In gemology, "opaler" is not a standard technical term. However, it is sometimes used informally to describe a gemstone that exhibits opal-like properties, such as play-of-color, but may not meet the strict definition of precious opal. This could include common opal, which lacks the iridescent display, or hydrophanous opal, which can absorb water and change its appearance.

The term "opaler" might also be associated with the process of treating or enhancing opals, though again, this is not a widely recognized scientific term. Such treatments are often aimed at improving the color, clarity, or stability of the gemstone. Historically, various methods have been employed to alter the appearance of opals, sometimes to mimic the look of more valuable specimens. It is important for consumers to be aware that treatments can affect an opal's value and durability.

In some contexts, particularly in older literature or regional dialects, "opaler" might be a misspelling or an archaic form of "opal." Given the lack of a definitive, universally accepted definition, the precise meaning of "opaler" often depends on the context in which it is used. When encountering this term, it is advisable to seek clarification or consider the surrounding information to understand its intended meaning.
