How it forms
Stibnite forms primarily in hydrothermal veins and is the most common ore mineral of antimony. Sharp striated prisms may extend from quartz or sulphide-rich matrix.
These are representative geological or commercial sources, not certified provenance for an individual stone. Country of origin should be substantiated independently when relevant to value.
01 / THE GEM AT A GLANCE
What is Stibnite?
Stibnite belongs to antimony sulphide mineral. Its principal chemical designation is Sb₂S₃; typical appearances include silvery lead-grey to grey-black, and a reported Mohs scratch hardness of 2. Stibnite forms primarily in hydrothermal veins and is the most common ore mineral of antimony. Sharp striated prisms may extend from quartz or sulphide-rich matrix. Hardness does not guarantee impact resistance or chemical safety.
Composition: Sb₂S₃. Scientific properties apply to the mineral or gem type, not as a guarantee about an untested individual product.

Hardness does not guarantee impact resistance or chemical safety. Metallic grey long bladed or needle-like crystals clustered into dramatic sprays, with a heavy, delicate appearance. Its metallic colour can resemble bismuthinite or other sulphides; long striated blades, softness and verified chemistry help distinguish it. Reference localities include China; Japan; Romania; United States, but that list does not authenticate the provenance of a particular stone. Choose intact terminations and stable matrix. Avoid items that shed dust, have been spray-painted, are welded to a stand without disclosure or are suggested as jewellery. For an expensive example, confirm mineral identity with a reputable laboratory or established specialist where appropriate; neither the educational illustration nor the seller's marketing text is a certificate. Collector display only; too soft, brittle and chemically inappropriate for jewellery or handled crystal sets. Keep dry and enclosed where practical; avoid handling needles directly. Never brush vigorously, polish, heat, or use acidic household cleaners. Historically associated with antimony extraction and early cosmetic traditions; historical use is not evidence of safety. Antimony-bearing mineral: do not grind or inhale dust, and keep away from food, children and pets.

Before you choose a stone
Compare images taken in more than one lighting condition, ask for views of the actual item and check how the cut and setting change its appearance. A gemstone type is not a standard grade: each natural specimen has its own colour, inclusions and workmanship.

03 / BUY WITH CONFIDENCE
Natural, laboratory-grown, treated or imitation?
Choose intact terminations and stable matrix. Avoid items that shed dust, have been spray-painted, are welded to a stand without disclosure or are suggested as jewellery. For an expensive example, confirm mineral identity with a reputable laboratory or established specialist where appropriate; neither the educational illustration nor the seller's marketing text is a certificate.
These distinctions should be clear in the listing for any particular gem. Treatments are not automatically unacceptable, but an undisclosed treatment, vague mineral identity or unsupported origin claim prevents an informed purchase. Where material identity materially affects value, an independent gemological identification report may be worth considering.

One essential care distinction
Mohs hardness describes resistance to scratching, not resistance to breaking. Gemstones with cleavage, existing fractures, porous surfaces or fillings can need extra care regardless of their hardness number. If you do not know whether a piece has been treated, begin with the gentlest appropriate cleaning method.

Traditional meanings and spiritual associations are part of cultural storytelling. They are not evidence that a gemstone diagnoses, prevents or treats any medical condition.
