Pyrite on Quartz Cluster — China

Weight: 217 g
Approx. size: 8 × 7 × 3 cm
Minerals: Quartz with Pyrite
Condition: Natural, unpolished specimen
UV reaction: None observed
Origin: China (exact locality unknown)

Description

This natural Quartz crystal cluster with Pyrite formed deep underground in a hydrothermal environment, where hot, mineral-rich fluids circulated through fractures in the surrounding rock.

Clear to milky quartz crystals grew first, forming the sharp points and layered crystal structure. Iron- and sulphur-rich fluids later deposited pyrite, which crystallised into the distinctive brassy-gold cubic forms scattered across the surface of the quartz. The result is a striking contrast between bright white crystal points and metallic gold tones.

Some pyrite crystals show minor natural surface tarnish, which can create subtle iridescent flashes. This is a normal and expected feature of natural pyrite and confirms the specimen has not been treated or enhanced.

Approximate Geological Age

Quartz–pyrite mineralisation of this type in China is generally associated with Mesozoic hydrothermal activity.

This specimen is estimated to have formed approximately:

90–150 million years ago

Long before human history, during a time when dinosaurs still roamed the Earth.

Why this piece is special

• Well-defined pyrite cubic crystals rather than massive growth

• Dense, natural quartz crystal coverage with good depth

• Strong visual contrast between quartz and metallic pyrite

• Displays beautifully from multiple angles

• A classic and collectable mineral association

Care Notes

Quartz is durable, but pyrite should be kept dry. Avoid water, chemicals, or prolonged humidity to preserve the metallic lustre. Handle gently to protect crystal points.
