Very clear citrine crystal with great tourmalines

A very clear citrine crystal from Brazil with embedded tourmalines. The high transparency of the quartz matrix provides an unobstructed view of the dark tourmaline rods, making the multi-mineral constellation particularly legible.

Citrine is the yellow iron-bearing variety of quartz and crystallizes in volcanic geodes of the Serra Geral basalt formation. Tourmaline, a complex boron silicate, typically grows in pegmatitic deposits.

Joint deposits within a quartz crystal document synchronous mineralization phases with boron-containing solutions. Such multi-component citrines are regarded as premium gemmological specimens in the collector's market.

The gallery dimension of this piece allows for backlighting with dramatic light refraction on the tourmaline rods. The clear separation between warm citrine yellow and deep black tourmaline black is striking.

A Brazilian collector's piece with two-mineral genesis and exceptionally high quartz clarity.
