Collection: Opal


Iridescent and Intuitive 

Opal is a gemstone unlike any other, famous for its mesmerizing play-of-color that shifts with the light. This unique phenomenon, caused by the diffraction of light within the stone's silica structure, makes each opal completely one of a kind. Found in a variety of shades – from fiery reds to deep blues and soft pastels – opal is a captivating choice for collectors and jewelry lovers alike.

The magic of play-of-color 

Opal’s iridescent flashes, ranging from vivid reds and oranges to blues and greens, are created by light diffraction in its microscopic silica spheres. This phenomenon makes every Opal unique.

Symbolism and meaning 

Often seen as a stone of inspiration and creativity, Opal has been associated with intuition, imagination, and emotional expression. Its shifting colors symbolize the ever-changing nature of life.

Opal in jewelry 

With a Mohs hardness of 5.5–6.5, Opal is relatively soft and best suited for earrings, pendants, or carefully protected ring settings. Its unique beauty makes it a prized gem, but one that requires thoughtful wear.
