Citrine double-terminated crystal with great smoky quartz phantoms

A Citrine double-terminated crystal from Brazil with distinctly visible smoky quartz phantoms. The geometric phantom lines are clearly delineated within the warm quartz interior.

Double-terminated crystals grow freely in the geode solution without being attached to the geode wall. Both ends are pointed, and this configuration documents the crystal's free movement in the solution during growth.

Brazilian citrine deposits in Rio Grande do Sul supply this material from the Serra Geral basalt formation. The natural golden color is created by iron substitutions in the quartz lattice, without subsequent heat treatment.

Its compact size makes this piece a classic jewelry or collector's item. Double-terminated crystals are a separate classification in the collector's market compared to standard single-terminated crystals.
