Comments:
───────

This stone exhibits white with play of orange, yellow and green. Due to its natural porosity, this gemstone may absorb liquids and as a result its weight and appearance may change.

PLAY-OF-COLOR PHENOMENON: The spectacular rainbow flashes result from light diffraction through microscopic silica sphere arrays within the opal's structure. Unlike simple body color, play-of-color is an optical phenomenon that appears to dance and shift as the stone moves - this is opal's most celebrated and valuable characteristic, elevating it far above common opal without color play.

NATURAL POROSITY DISCLOSURE: Opal's natural porosity is an inherent characteristic of this gemstone species, not a defect. This porosity can cause slight weight fluctuations with humidity changes and allows the stone to potentially absorb liquids. This is normal for natural opal and demonstrates authenticity. Proper care includes avoiding prolonged water exposure and storing in moderate humidity.

COLOR PLAY SIGNIFICANCE: The presence of orange, yellow, and green flashes against white body represents classic precious opal. This multi-color display indicates well-ordered silica sphere arrangements creating optimal diffraction patterns. The variety of colors visible demonstrates the quality of the internal structure.

TREATMENT TRANSPARENCY: The "See Comments" treatment status reflects opal's natural characteristics. Any treatments to stabilize or enhance opal would be disclosed. The porosity comment confirms this is natural opal with authentic characteristics rather than synthetic or heavily treated material.

CARE RECOMMENDATIONS: Opal requires gentle care due to water content and porosity. Avoid harsh chemicals, ultrasonic cleaners, extreme temperature changes, and prolonged water immersion. Store in moderate humidity away from heat sources. Clean gently with soft cloth. These precautions ensure long-term beauty and play-of-color preservation.

Clarification on "See Comments" treatment disclosure: When a certificate states "See Comments" under treatments, this provides important information about the stone's natural characteristics. The porosity comment confirms this is authentic natural opal. We sell all stones with full transparency and competitive market pricing.
