Description :

Aventurine

Aventurine is a variety of quartz that contains tiny mineral inclusions—usually mica, fuchsite, or hematite—that create a subtle sparkle called aventurescence. Traits:

  • Soft to medium green, often slightly translucent

  • Shimmery or glittery effect when turned in the light

  • Smooth, even texture Origin: Forms in silica‑rich environments where small plate‑like inclusions get trapped during quartz growth.


Bloodstone (Heliotrope)

Bloodstone is a dark green chalcedony with distinctive red spots caused by iron oxide. Traits:

  • Deep, almost forest‑green base

  • Red flecks or splashes that look like droplets

  • Opaque and dense Origin: Forms in silica‑rich hydrothermal systems; the red inclusions are hematite or jasper.


Amazonite

Amazonite is a green to blue‑green variety of microcline feldspar. Traits:

  • Bright turquoise‑green color

  • White streaks or grid‑like patterns

  • Slightly pearly sheen Origin: Found in granitic pegmatites—slow‑cooling pockets of magma that allow large feldspar crystals to form.


Green Tree Agate

Despite the name, this isn’t actually an agate in the strict sense. It’s a white chalcedony with green dendritic (branch‑like) inclusions. Traits:

  • White or pale background

  • Mossy, branching green patterns that resemble foliage

  • Opaque to slightly translucent Origin: The “tree” patterns come from manganese or iron minerals that seep into fractures as the stone forms.
