Pink opal is a beautiful variety of common opal, known for its soft, pastel pink hues. Unlike precious opals, it does not exhibit the dazzling "play-of-color" phenomenon. Instead, its charm lies in its gentle, solid coloration, making it a popular choice for jewelry and decorative items.
Understanding Pink Opal's Characteristics
Pink opal is a unique gemstone with several distinct properties that set it apart from other opal varieties.
- Appearance and Transparency: Pink opal can range from semitranslucent to opaque, often displaying a creamy, soothing pink color. Its surface can be smooth and polished, highlighting its soft glow.
- Origin of Color: The delicate pink color of this opal has been attributed to the presence of minute inclusions of the silicate mineral palygorskite, sometimes also known as attapulgite, in addition to certain organic compounds found within its structure. This combination creates the signature rosy shade.
- Absence of Play-of-Color: A key characteristic defining pink opal as a "common" opal is its lack of play-of-color. Unlike precious opals that diffract light into a vibrant rainbow spectrum, pink opal offers a consistent, stable color throughout the stone.
Where is Pink Opal Mined?
The primary sources for pink opal are located in Latin America. This captivating gemstone is predominantly mined in Mexico and Peru. Peruvian pink opal, in particular, is highly regarded for its often vibrant and consistent coloring.
