Description :

Quartz (the clear crystals)

These are the prismatic, glassy crystals — the ones with sharp points and good clarity.

How to recognize them

  • Transparent to milky

  • Six‑sided prism shape

  • Hard, glassy luster

  • Often grows in clusters

What your pieces show

  • A large, elongated quartz point with a slight yellow tint at the base

  • Smaller individual points

  • A compact quartz cluster with intergrown crystals

Quartz forms in cavities where silica‑rich water cools slowly, letting the crystals grow into those classic shapes.


Selenite (the “fish tail”)

Selenite is a form of gypsum — soft, silky, and often forming in blade‑like crystals. The “fish tail” variety forms when two selenite blades grow together in a V‑shape.

How to recognize it

  • Soft, silky sheen

  • Bladed or fan‑shaped crystals

  • Often forms twinned shapes (like a fishtail)

  • Softer than quartz — scratches easily
