Great Citrine Double Terminated Crystal

A Citrine Double Terminated Crystal from Brazil in a balanced collector size. Both ends clearly formed as pyramids, with a uniform golden color tone and a transparent hexagonal column in the middle.

Double terminated crystals grow freely in the geode solution without being attached to the geode wall. Both ends form into points. This constellation documents the free movement of the crystal in the solution during growth.

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

Citrine belongs to the quartz family with a Mohs hardness of 7. Naturally colored material is valued significantly higher in the collector's market than heat-treated amethyst.

A compact jewelry or collector size. Double terminated crystals are a separate classification in the collector's market compared to standard single terminated crystals.
