美丽的印度 Scolecite 晶洞（共 3 件）。

Scolecite 是一种矿物——一种水合钙铝硅酸盐（折射硅酸盐）——属于沸石族。

Scolecite 是典型的纤维状沸石，具有单斜晶系结构，由一个二元轴和一个对称平面所特征。Scolecite 的密度为 2.3 g/cm³，莫氏硬度为 5.5。它具有良好的解理和贝壳状断口。通常以薄、带状的棱柱晶体形式出现，呈白色或无色，聚集成扇形簇状或纤维状放射状团块。Scolecite 的棒状晶体比 natrolite 的要厚，尽管两者常在肉眼下不易区分，因为它们彼此极为相似。

此批次由 3 个晶洞组成，单件重量大致为：

总重量：大约 0.45 kg

Beautiful Indian Scolecite Geode (lot of 3).

Scolecite is a mineral — a hydrated calcium and aluminium silicate (tectosilicate) — belonging to the zeolite group.

Scolecite is the typical fibrous zeolite, possessing a monoclinic crystal structure characterised by a single binary axis and one plane of symmetry. Scolecite has a density of 2.3 g/cm³ and a hardness of 5.5 on the Mohs scale. It shows good cleavage and a conchoidal fracture. It occurs as thin, striated prismatic crystals, white or colourless, gathered in fan-shaped clusters or fibrous-radiating masses. Scolecite's rod-like crystals are thicker than those of natrolite, though the two are not always easy to tell apart with the naked eye, as they closely resemble one another.

The lot consists of 3 geodes with individual weight of approximately:

Total weight: approximately 0.45 kg
