Description
This 2-inch Onyx paperweight is carved from authentic calcite onyx, a naturally banded form of calcium carbonate (CaCO₃). It originates from the Balochistan region of Pakistan, known worldwide for its fine deposits of translucent green and amber-toned onyx.
Unlike chalcedony-based onyx, this stone is sedimentary in origin, forming through the slow precipitation of calcium carbonate from mineral-rich groundwater in limestone caverns. Over thousands of years, rhythmic deposition created alternating bands of calcite and aragonite, resulting in the soft striations that define this material.

Formation and Geologic Significance
The onyx used in this paperweight was formed as groundwater percolated through limestone caves, leaving behind calcium carbonate deposits in concentric layers. Trace elements are responsible for its natural colors:
-
Green hues from nickel or chlorite inclusions.
-
Amber and honey tones from iron oxide.
-
Cream and white layers from pure calcite.
Each band represents a unique mineralogical event — tiny chemical variations across centuries — making every onyx paperweight a distinct snapshot of geologic time.
Physical Characteristics

-
Origin: Balochistan, Pakistan
This onyx paperweight’s smooth polish and weighted feel make it both functional and decorative, suitable for office desks, study spaces, or as an elegant accent in home interiors. Its natural translucency allows light to softly illuminate the bands, revealing fine mineral layering.
Uses and Applications
-
Desk or office paperweight — combines beauty and practicality.
-
Home décor accent — ideal for natural stone enthusiasts.
-
Collector’s display — a fine example of calcite onyx banding.
-
Educational specimen — demonstrates carbonate layering and sedimentary mineral formation.

Metaphysical Notes
Symbolically, Onyx represents strength, stability, and focus. The layered appearance mirrors emotional and mental balance, making this paperweight a grounding presence for work or meditation spaces. Its natural striations are often seen as reminders of patience, endurance, and the beauty of gradual growth.
Care and Handling
-
Wipe with a soft, dry or slightly damp cloth.
-
Avoid acids, vinegar, or harsh cleaners (which can dissolve calcite).
-
Keep out of direct sunlight to preserve color and polish.
