Quartz cluster - Mine à Giraud, Isère, France

A beautiful cluster of numerous quartz crystals, forming a particularly attractive and well-developed cluster.

The crystals exhibit the classic Dauphiné habit, with well-defined faces and sharp terminations. Several crystals are transparent to translucent and display a beautiful luster, lending the entire piece a brilliant sparkle.

The arrangement of the crystals, with several well-defined points oriented in different directions, gives the specimen an airy and dynamic appearance.

The entire specimen rests on a discreet matrix base that effectively highlights the crystalline cluster.

6.4 × 4 × 3.4 cm

Highlights of this specimen:

- Classic Dauphiné habit.
- Smooth, lustrous crystal faces.
- Several well-defined points.
- Beautiful transparency to translucency in the crystals.
- Aesthetic and dynamic cluster.

For your information:

The Giraud Mine, located in Isère in the Bourg-d’Oisans area, is associated with the neighboring mineralizations of La Gardette. Quartz from this area is particularly sought after for the quality of its crystallization and its habit typical of the Dauphiné region.
