How Much Is Howlite Worth?
A soft, chalk-white stone laced with grey webbing — cheap and cheerful on its own terms, but best known as the porous rock that is dyed blue and sold as “turquoise.”
Howlite is the stone most people own without knowing it. On its own it is an unassuming chalk-white to pale-grey material threaded with fine grey or black veins in an erratic, web-like pattern — not showy, but quietly attractive when polished. It was first described in 1868 near Windsor, Nova Scotia, and named after the Canadian chemist and geologist who brought it to notice. It is soft, porous and abundant, which has made it a workhorse of the cheap-jewellery and craft trade for decades.
That porosity is also why howlite is famous for the wrong reasons. Because it soaks up dye so readily, white howlite is routinely coloured to imitate pricier stones — most often dyed a sky-blue and sold as “turquoise,” “white turquoise” or “buffalo turquoise,” and sometimes dyed red, green or black. Its honest value is modest and its natural look is pleasant, so the key to buying howlite well is knowing that it is cheap, recognising when you are looking at dyed material, and never paying turquoise money for a dyed white rock.
Key takeaways
- It is genuinely cheap. Howlite is abundant and inexpensive; even nice carvings and spheres cost little, so it is a low-risk beginner’s stone.
- The webbing is the natural charm. Crisp grey-to-black veining on a clean white body is what to look for in undyed pieces.
- It is soft and porous. At about Mohs 3.5 it scratches easily and absorbs liquids and dye, so it needs gentle wear and care.
- It is the classic turquoise imitator. Dyed blue howlite is one of the most common fake “turquoises” on the market — know the difference before you buy.
- Dye does not add real value. A dyed howlite bead is still a cheap howlite bead; pay for it as howlite, not as the stone it imitates.
What howlite actually is
Howlite is a calcium borosilicate hydroxide — a borate mineral — that typically forms as white, nodular masses with a texture rather like unglazed porcelain, veined with grey or black threads of host rock. Clean, well-formed crystals are rare; almost all howlite on the market is the massive, opaque nodular material, which is why it is cut into cabochons, beads, spheres and small carvings rather than faceted. Its natural colour is white to pale grey, and the interest lies in the contrast between the pale body and the dark, erratic webbing.
On the Mohs scale it is soft — around 3.5 — so it scratches easily and is best kept away from harder stones and rough handling; its porous structure also means it readily absorbs oils, cosmetics and, crucially, dye. The classic source is Nova Scotia in Canada, where it was first found, with significant deposits in California and other localities. Because its natural webbing resembles the matrix veining of turquoise, and because it dyes so willingly, howlite has become the go-to material for imitating turquoise — a role that dominates its reputation. For the genuine article it is so often faked as, see our guide to turquoise.
How it is valued
Value is modest and driven by look and workmanship rather than rarity. For natural material, the appeal is a clean white body with crisp, well-defined grey-to-black webbing; muddy, dull or featureless pieces are worth less. Polish and condition matter, since a soft stone shows scratches and chips quickly, and size and workmanship lift the best pieces — a large, smoothly turned sphere or a neatly carved figure is worth more than a handful of tumbled chips, even though the raw material costs almost nothing. Dyeing does not add genuine value: a dyed-blue howlite bead is still an inexpensive howlite bead, and should be priced as such. If a seller presents dyed howlite as turquoise or another stone, the honest-disclosure standards in our guide to gemstone treatments and disclosure are exactly what is missing.
Typical fair prices
| Grade | Indicative fair price | Notes |
|---|---|---|
| Tumbled / bead strand | $1–$4 each | Rounded pieces and drilled strands, natural or dyed |
| Cabochon / small carving | $4–$15 per piece | Clean white body with crisp grey webbing |
| Larger sphere / worked carving | $15–$50+ per piece | Bigger, well-polished, well-figured display pieces |
| Dyed “turquoise” howlite | Price as howlite | Dye adds no real value; do not pay turquoise money |
These are Fair Carat’s synthesis of observed dealer and craft-supply listings, not survey data. Howlite is cheap enough that webbing, polish and workmanship — not size — do most of the work in setting value, and the single most important price rule is simply to buy dyed howlite as howlite.
Watch-outs
- Dyed and sold as turquoise. Blue-dyed howlite is the most common turquoise imitation; tell-tale signs are dye pooled in the veins, colour that rubs off with acetone, and a suspiciously low price for “turquoise.”
- Trade-name cover. “White turquoise,” “white buffalo” and “buffalo turquoise” are often just howlite (or magnesite); ask what the material actually is, and read our guide to reading a lab report.
- Softness and wear. At Mohs 3.5 howlite scratches, chips and dulls easily; it is not a hard-wearing ring stone and needs gentle handling.
- Porosity. It absorbs oils, perfume and water, which can stain or weaken it; keep it dry and away from cosmetics.
- Marketing hype. “Calming” and sleep claims are folklore, not a reason to pay more — and certainly not a reason to buy dyed howlite as something rarer; see our look at gemstones as an investment.

Buy it as honest, inexpensive howlite — not as “turquoise.”
The nicest natural howlite shows a clean white body with crisp grey-to-black webbing and a smooth polish. Favour well-worked cabochons, beads or carvings, accept that it is soft and inexpensive, and if a piece is dyed blue make sure you are paying howlite prices rather than turquoise ones.

FAQ
Is howlite worth anything?
Only a little, and that is the honest answer. Howlite is abundant and cheap: tumbled pieces and beads cost a dollar or two, and even nice carvings and spheres stay inexpensive. Its value is in being an attractive, affordable ornamental stone, not a precious gem — and dyeing it does not change that.
Is blue howlite the same as turquoise?
No. “Blue howlite” is white howlite that has been dyed to look like turquoise. It is a cheap imitation, not the real mineral, and should be priced as howlite. If you want genuine turquoise, buy it as turquoise from a seller who discloses treatment — and be suspicious of “turquoise” offered at howlite prices.
How can I tell dyed howlite from natural turquoise?
Look at the veins: on dyed howlite the colour often pools darker in the cracks and can rub off on a cotton bud dipped in acetone. Dyed howlite is also usually cheaper, more uniform and softer than turquoise. When in doubt, ask the seller directly and favour material sold honestly as dyed howlite.
Is howlite hard enough for jewellery?
Only for gentle wear. At about Mohs 3.5 it is soft, so it scratches, chips and dulls far more easily than quartz or turquoise. It is fine for pendants, earrings and occasional-wear beads, but a poor choice for everyday rings; keep it away from harder stones and abrasives.
Why is howlite so often dyed?
Because it is white, porous and cheap. Its natural veining already resembles turquoise matrix, and its porous texture soaks up dye evenly, so a little colour turns an inexpensive white rock into a convincing — and profitable — turquoise look-alike. That combination is exactly why so much “turquoise” jewellery is really dyed howlite.
Where does howlite come from?
It was first described near Windsor, Nova Scotia, in 1868, and Canada remains a classic source. Large deposits are also worked in California and elsewhere. Wide availability is part of why howlite stays so cheap — and why it is used in such volume for beads and dyed imitations.
