How much does Stibnite cost?

Stibnite is an antimony sulfide mineral (Sb₂S₃) and the principal ore of antimony, prized for its long, striated, steel-gray prismatic crystals. Stibnite crystallizes from low-temperature hydrothermal solutions, typically between 100-300°C. It forms in veins associated with hot springs and volcanic activity, often alongside quartz, calcite, and other sulfide minerals.

The crystals grow in elongated prismatic habits that can reach remarkable sizes. The famous Ichinokawa Mine in Japan produced sword-like crystals exceeding half a meter in length. These dramatic formations develop when antimony-rich fluids flow through fractures in the host rock and conditions remain stable long enough for slow, uninterrupted crystal growth.

Stibnite is the primary ore of antimony, a metalloid used in flame retardants, lead-acid batteries, and alloys. Ancient civilizations ground stibnite into powder for use as kohl eyeliner, a practice dating back to ancient Egypt and Mesopotamia.

Identification Guide

Stibnite's long, striated prismatic crystals with brilliant metallic luster make it one of the most visually distinctive minerals. The crystals are often bent or curved, a result of the mineral's extreme softness (Mohs 2) and perfect cleavage in one direction. You can scratch it with a fingernail.

Distinguish from galena (cubic crystals, higher hardness), bismuthinite (very similar but rarer and slightly harder), and metallic tourmaline (much harder, different crystal habit). Stibnite will melt in a match flame, which is a reliable but destructive test.

Spotting Fakes

Stibnite is rarely faked because it's relatively affordable and abundant. The main concern is damage from cleaning. Many Chinese specimens are cleaned with acids that can leave surfaces dull or pitted. The best specimens retain their natural metallic brilliance. Avoid specimens that look unnaturally uniform or suspiciously shiny, as they may have been coated.

Affiliate picks

Stibnite gets imitated with glass, dyed stand-ins, and cheaper lookalikes. These four tools run the checks in the Spotting Fakes section above, so you can tell real from fake before you pay - online, at a show, or in a shop.

10x triplet jeweler's loupe$20-40
The first tool worth owning. Round gas bubbles (glass), dye pooled in cracks (dyed howlite, magnesite, agate), and flow lines are invisible to the naked eye and obvious at 10x. A triplet lens keeps the edges sharp.
Shop on Amazon
Mohs hardness pick set~$40
Calibrated picks settle the cheap swaps in seconds - howlite (3.5) sold as turquoise (5-6), glass (5.5) sold as quartz (7). Faster and more accurate than the fingernail-and-knife method.
Shop on Amazon
0.01g digital pocket scale~$15
Density catches what the eye misses. A glass 'quartz' weighs suspiciously light; lead-loaded plastic 'lapis' weighs suspiciously heavy. Weigh, compare to the known density, and flag the mismatch before the money leaves your hand.

365nm UV flashlight$20-30
Many stones have a distinctive fluorescence (hyalite opal, fluorite, ruby, scheelite). A longwave UV light is the fastest tiebreaker when a piece passes the other tests but still looks off.

Cultural & Metaphysical Traditions

Presented as cultural traditions, not scientific evidence

Crystal practitioners associate stibnite with transformation and the ability to navigate dark or uncertain periods. Its sword-like crystal habit has made it a symbol of cutting through illusion. Some traditions use it for meditation on shadow work. Handle with care and wash hands after, as stibnite contains antimony.

Metaphysical and “healing” associations are cultural traditions, not medical advice or scientific fact. Crystals are not a substitute for professional medical care.

Good to Know

💎

Scratch test: At hardness 2, Stibnite can be scratched with a fingernail. This is a display specimen, not a wearable stone.

🌍

Global supply: Found in 4 notable locations worldwide, from Japan to United States.

⚖️

Heft test: Stibnite has a specific gravity of 4.63 - noticeably heavier than quartz. You'll feel the density when you pick it up.

Care & Safety

What stibnite can and cannot tolerate, based on its hardness (Mohs 2) and chemistry (Sb₂S₃).

Can Stibnite go in water?

Not recommended. At Mohs 2, stibnite is soft enough that water can dull, etch, or degrade the surface. Clean it with a dry cloth instead. Important: stibnite contains antimony. Never use it for gem elixirs or crystal-infused water, and wash your hands after handling it.

Can Stibnite go in salt water?

No. Stibnite should stay away from water in general, and salt water is worse on every count: dissolved salt is corrosive while the stone is wet, and abrasive salt crystals are left behind in cracks and crevices as it dries.
