This Fire Opal in Matrix comes from the San Juan del Rio Municipality in Querétaro, Mexico, a locality known for producing vibrant opal seams within volcanic host rock. The specimen is a natural cluster of three pieces, originally acquired through Crystal Classics, a dealer recognized for museum‑quality mineral specimens. The opal shows warm orange to red body color typical of Mexican fire opal, set within a contrasting rhyolitic matrix that highlights the opal’s natural formation environment.

The matrix preserves the opal in its original geological context, showing how the opal filled fractures and cavities during volcanic activity. This association creates a visually dynamic specimen with both structural interest and strong locality character. The trio format adds display versatility, allowing the pieces to be arranged together or individually while still maintaining their shared provenance. With its origin, acquisition history, and intact matrix structure, this set represents a refined example of Mexican fire opal suitable for collectors who appreciate locality‑specific mineral formation.
