White Buffalo
White Buffalo is carbonate-silicate rock (trade-name gemstone). In the hand, it rates 3 to 6 (variable mix) on the Mohs scale, and it runs bone white with black web and white with grey-black matrix patches. Mid-range; genuine Tonopah material commands respectable prices.
The geology.
White Buffalo carries the formula Mixed: calcite/dolomite/magnesite with black chert. It belongs to the none (massive mixture) system. On paper it is carbonate-silicate rock (trade-name gemstone).
It sits at 3 to 6 (variable mix) on the Mohs scale. The surface reads waxy to dull. Light behaviour is opaque. Specific gravity runs 2.6 to 2.9. The streak is white. It breaks with uneven to splintery fracture.
Striking white stone webbed with jagged black matrix, cut for Southwestern jewelry, it is a white carbonate rock with black chert, not turquoise, since turquoise without its copper color simply is not turquoise.
Expect to see it as cabochons, beads or Southwestern jewelry inlay.
The origins.
Mined by the Otteson family near Tonopah, Nevada, found in association with true turquoise deposits.
On value, the database notes: mid-range; genuine Tonopah material commands respectable prices.
Traditional associations.
In energy work traditions, White Buffalo is treated as a stone of clarity and spiritual communication, echoing the sacred white buffalo of Plains lore.
Recorded here because it is part of how this material is sold, not because it is a property of the material.
Spotting the real thing.
Striking white stone webbed with jagged black matrix, cut for Southwestern jewelry, it is a white carbonate rock with black chert, not turquoise, since turquoise without its copper color simply is not turquoise.
Double trouble: the name implies turquoise it isn't, and the stone's popularity has spawned resin and dyed-magnesite copies, buy from Southwestern dealers who name the mine.
| Looks like | How to tell them apart |
|---|---|
| Howlite | Howlite's veins are soft grey spiderwebs; White Buffalo's matrix is bold black chert islands |
| White 'buffalo' resin fakes | Plastic copies feel warm and light and smell on a hot needle, the popular stone is itself now faked |
| Magnesite | Plain magnesite lacks the dramatic black web and carves softer |
At-home tests.
None of these need a lab. A 10x loupe, good daylight and a steady hand cover most of what a buyer needs to know about white buffalo.
| Test | What you should see |
|---|---|
| Acid check | Vinegar fizz on a hidden spot betrays the carbonate body |
| Scratch check | Black matrix (chert) is glassy-hard while white body scratches more easily |
| Provenance | genuine material traces to the Tonopah, Nevada claims |
If these checks leave you unsure, that is what appraisers are for. Do not file, heat or soak a piece to find out.
Care & handling.
At 3 to 6 (variable mix) on the Mohs scale this is a soft material. Keep it as a display piece, store it apart from harder stones, and skip daily-wear settings.
It breaks with uneven to splintery fracture, which is worth knowing before you set it or drop it.
Most damage happens during cleaning, not wearing. Avoid steamers, ultrasonic tanks and anything from under the sink.

One more thing
Marketed as 'white turquoise', it contains none: turquoise owes its blue to copper, so a truly white turquoise is a contradiction, yet the stone became a Southwestern jewelry star on its own looks.
