Smoky Quartz in a Half-Geode – Mooralla, Australia

This specimen features a half-geode whose cavity is largely lined with small, colorless quartz crystals.

At the center of the geode is a cluster of smoky quartz crystals, with smoky brown hues. The crystals are well-defined, with brilliant faces and good transparency that allows one to see their volume and some internal inclusions.

The contrast between the darker smoky quartz crystals and the carpet of clear quartz surrounding them gives the specimen great depth.

5.5 × 4.3 × 2.5 cm

Highlights of this specimen:

- Well-defined smoky quartz in the center of the geode
- Crystals with good transparency and brilliant faces
- Striking contrast between the smoky quartz and the clear quartz

For your information:

- Mooralla, in the state of Victoria, is a classic locality for Australian smoky quartz. The geodes form in weathered rhyolite belonging to the Rocklands Rhyolite, dating from the Upper Devonian period.
