Opal

Opal is a hydrated silica mineraloid admired for its vibrant colors and unique internal play-of-light. Found in shades ranging from white, black, clear, orange, green, blue, and yellow, opal forms in cavities and fractures where silica-rich water has deposited over time. Unlike crystalline minerals, opal is amorphous, lacking a defined crystal structure. Valued for both its beauty and variety, opal remains one of the most captivating gemstones for collectors.
