Condition Notes: Measuring approximately 14.85 x 9.15 x 6.00 mm, this opal is described as a water opal, a variety characterized by its transparent body and strong light transmission, most commonly associated with material from Mexico, particularly Querétaro. This example displays a good play of color, placing it closer to what is often termed crystal opal, where transparency is paired with visible spectral flashes. In contrast, white opal typically presents with a milky, translucent to opaque bodycolor due to internal light scattering, whereas this stone allows light to pass freely, producing a glassy, liquid like appearance.
The opal appears clean overall and free from notable crazing. The shank retains a bright, polished finish, with diamonds intact and showing no evident damage or loss.
Opal of this nature should be stored separately from harder gemstones in a soft pouch or lined compartment to prevent abrasion. A stable environment is recommended, avoiding excessive heat, dryness, or direct sunlight, as dehydration can lead to crazing. Sudden temperature changes should be avoided, and the piece should be removed during activities involving impact or chemical exposure. Cleaning is best performed with lukewarm water, mild soap, and a soft cloth; prolonged soaking is not recommended.
