Pink Opal

Hardness: 5-6 (Mohs scale), Color: Soft baby pink to bubblegum pink with white/cream mottling, Luster: Waxy to vitreous, Crystal Structure: Amorphous (Non-crystalline), Cleavage: None (Conchoidal fracture), Specific Gravity: 1.9-2.3

Formed through the accumulation of silica-rich water in cavities and cracks of volcanic rocks. The pink hue is derived from micro-inclusions of organic compounds or minerals like Palygorskite and Quinone. Most deposits were formed during the Tertiary period (roughly 66 to 2.6 million years ago).

Primarily used in jewelry for beads, cabochons, and carvings. Significant in the metaphysical market as a 'stone of peace' and highly valued by collectors for its unique non-iridescent pastel color.

Unlike 'Precious Opal', Pink Opal does not show the 'play of color' or fire. It is often referred to as 'Andean Opal' because the most famous and prolific mines are located in the Andes Mountains of Peru. It is considered the national stone of Peru.

Identify in the field by its distinct waxy luster and lack of transparency (translucent to opaque). Common locations include the Andes Mountains (Peru), Australia, and parts of the United States. In jewelry, look for the absence of internal 'flash' and a smooth, consistent pink color often showing white dendritic patterns.
