Obsidian Polished - Height: 21 cm - Width: 18 cm- 3350 g - (1)

Obsidian is not a mineral. It is glass. Lava cools so fast that no crystals ever get the chance to form, and what hardens instead is a natural glass — the same structure as a window pane, made by a volcano and then left to sit for a very long time. That is why it goes black and stays black: there is nothing inside it to scatter light.
This is a polished black obsidian ornament, 21 cm tall with its stand, 18 cm wide and 4 cm deep, weighing 3.35 kg. The form is a clean dome — a half-egg that rises from a flat base and curves over at the top, with no hard angles anywhere on it. The polish on obsidian takes very well, and here it has been worked to a near-mirror across the whole curve. Underneath, faint mottling drifts through the black: traces of dark green and brown, the last unevenness of the cooling, sitting deep rather than on the surface. The stone rests on a carved dark wooden stand cut to look like a slab of rough rock, its top edge left uneven.
Look at it:
A polished dome-form obsidian — 21 × 18 × 4 cm, standing on its stand.
Volcanic glass, not stone — natural obsidian, formed by lava cooling too fast to crystallise.
Deep, true black — dense and opaque, with faint green and brown mottling beneath the surface.
Near-mirror polish — high gloss across the whole curve, no dull patches.
Continuous silhouette — a smooth arc from base to crown, no hard corners.
Carved wooden stand — dark tone, cut as a rough rock slab, included.
It belongs on a desk, a console, or a display shelf — the quietest object in the room, and the one the eye keeps returning to.
Honest note: this is natural obsidian, a volcanic glass, polished and mounted on a carved wooden stand. Obsidian is softer than quartz and will mark if struck hard; it is a display piece, not a working surface. Faint mottling in the surface is natural to the material. The exact stone and stand shown are the ones you receive.
