Septarian with calcite druse from Madagascar, in egg shape.
Carved septarian egg, from Madagascar, with a natural calcite druse. This piece shows the characteristic structure of septarian, with dark calcite veins delimiting areas of beige and brown tones. An internal cavity reveals a layer of small calcite crystals, distinctive of this type of geological formation.
Main features:
- Approximate dimensions: 14.5 cm high x 9.5 cm diameter
- Approximate weight: 1.79 kg
- Origin: Madagascar
- Type of piece: Carved septarian druse
- Visible minerals: Calcite
- Peculiarities: Unique piece with drusy cavity
Crystallization and cavity:
The piece presents a natural cavity covered by small calcite crystals. This forms as part of the internal structure of the septarian, a result of the geological process that filled the cracks in the rock. The velvety luster of the calcite crystals contrasts with the main matrix of the septarian.
Natural formation and matrix:
Septarian is not a mineral; it is a geological formation originated by the solidification of a rock nodule that, upon drying, cracked. These cracks were filled with minerals such as calcite, which crystallized forming the dark veins visible on the surface and the internal druse. The name septarian derives from the Latin septum, referring to the compartment structure formed by these veins.
Decorative and collection use:
This specimen is suitable for decoration and collecting. Its egg shape, with a crystallized cavity, makes it a distinctive piece. The tonality and pattern of the veins are characteristic of Madagascar septarian.
To consider:
This is a unique piece; the exact specimen shown in the images will be sent. Due to its nature, it may present irregularities typical of geological formation, such as variations in color and texture, cracks and fissures. The cavity may contain small imperfections. Calcite crystals can be fragile at the edges of the cavity. The stand shown in the images is not included.
