Is howlite the same as turquoise?

No. Howlite is a naturally white calcium borate mineral commonly dyed blue and sold as turquoise. It contains no turquoise. Real howlite in its natural white state is also used in jewelry but should be disclosed as howlite, not turquoise.

Is variscite turquoise?

No. Variscite is a green phosphate mineral with a chemical composition close to turquoise but distinct from it. Found primarily in Utah and Nevada, it is often mistaken for green turquoise like Carico Lake or King's Manassa, but it is its own stone with its own collector market.

Is reconstituted turquoise the same as real turquoise?

Not quite. Reconstituted turquoise contains real turquoise dust or fragments bonded with resin and pressed into a manufactured material. It contains turquoise but is not a natural stone. It should always be disclosed as reconstituted on listings.

What is chrysocolla and is it turquoise?

Chrysocolla is a hydrated copper silicate that produces vivid blues and greens often mistaken for turquoise. Both stones contain copper, which is why the visual confusion is understandable. But chrysocolla is its own distinct mineral, generally softer than turquoise, and should be disclosed as chrysocolla.

How do I tell dyed howlite from real turquoise?

Howlite is much softer than turquoise. A fingernail can scratch dyed howlite but will not affect real turquoise. Dye sometimes pools in surface cracks of howlite rather than penetrating the stone. Under a 10x loupe, dyed howlite often looks chalky and the gray veining appears more uniform than the irregular matrix of real turquoise.

Stones Commonly Mistaken for Turquoise

Q: Is White Buffalo actually turquoise?

Technically no. White Buffalo is a form of calcite or magnesite (the classification is debated) mined alongside turquoise in Nevada. It does not contain the copper that gives turquoise its blue color. But it is widely accepted within the Southwestern jewelry tradition and stands on its own merit.

Q: Is Larimar a type of turquoise?

No. Larimar is a blue variety of pectolite found only in the Dominican Republic. It produces colors that can resemble turquoise but the stones are mineralogically distinct. Larimar is properly disclosed by name and is not sold as turquoise by reputable sellers.

A clear reference for which stones are actually turquoise and which are not, including the most common substitutes you will encounter shopping online.

The turquoise jewelry market is full of stones that look like turquoise but are not turquoise. Some are honest substitutes. Some are deliberately sold as turquoise when they are not. Either way, knowing what you are looking at protects you from paying turquoise prices for something else.

This page covers the 8 stones we see confused with turquoise most often. For each, the short verdict, what the stone actually is, and how to tell it apart from real turquoise.

1. Howlite

Verdict: Not turquoise. White mineral, often dyed blue.

Howlite is the single most common turquoise substitute in the market. It is a naturally white calcium borate mineral with light gray veining. Dyed blue, it looks remarkably like turquoise to an untrained eye. Real howlite in its natural white form is also used in jewelry but should always be disclosed as howlite, not turquoise.

Tell: Howlite is much softer than turquoise. A fingernail can scratch it. Dye sometimes pools in surface cracks rather than penetrating the stone. Under a 10x loupe, dyed howlite often looks chalky and the gray veining appears more uniform than real turquoise matrix.

2. Magnesite

Verdict: Not turquoise. Magnesium carbonate, often dyed.

Magnesite is a naturally white to buff-colored mineral that takes dye well. Cheaper imported turquoise jewelry, especially what you see at flea markets or in bulk wholesale lots online, is overwhelmingly dyed magnesite. Wild Horse stone is a magnesite variant sold under its own name (and properly disclosed).

Tell: Softer than turquoise. Dye penetration is often uneven. The webbing tends to look chalky rather than the warm browns and blacks of real turquoise matrix.

3. White Buffalo

Verdict: Not turquoise. But genuinely White Buffalo and properly disclosed in the Southwestern jewelry tradition.

White Buffalo is technically a form of calcite or magnesite (the classification is debated) mined alongside turquoise in Nevada. It does not contain the copper that gives turquoise its blue color. But it is cut and set by the same makers, sold within the turquoise category in Southwestern jewelry shops, and stands on its own merit as a distinctive stone.

Tell: Real White Buffalo is hard and takes a deep polish. Soft white stones marketed as White Buffalo are usually dyed howlite or magnesite. Wildflower works a claim on the actual White Buffalo deposit near Tonopah, Nevada.

4. Variscite

Verdict: Not turquoise. A distinct mineral often mistaken for green turquoise.

Variscite is a green phosphate mineral with a chemical composition close to turquoise but distinct from it. Found primarily in Utah and Nevada, it can be very high quality and is collected in its own right. The visual confusion with green turquoise (especially Carico Lake or King's Manassa) is understandable but the stones are not the same.

Tell: Variscite tends to have a more uniform green and a slightly waxier appearance than green-leaning turquoise. Sellers who know their material will identify it as variscite specifically.

Read about variscite or compare to King's Manassa green-to-teal turquoise.

5. Wild Horse Stone

Verdict: Not turquoise. Magnesite with iron-oxide matrix.

Wild Horse stone is a magnesite variant from Arizona with cream, tan, and brown tones and characteristic reddish-brown matrix. It is not turquoise and should not be marketed as such, but it lives in the same Southwestern jewelry vocabulary and is properly disclosed by reputable sellers.

Tell: The warm earth tones and reddish matrix are distinctive. Wild Horse is the warm complement to turquoise, not a substitute.

6. Reconstituted or Block Turquoise

Verdict: Real turquoise material but a manufactured product, not a natural stone.

Reconstituted turquoise is made by grinding real turquoise dust or fragments, mixing them with resin, and pressing the result into blocks that can be cut into cabochons. It contains turquoise but is not a natural stone. Block turquoise is the fully synthetic equivalent (plastic or resin engineered to look like turquoise, no real turquoise content).

Tell: Reconstituted material looks too uniform across multiple cabs from the same batch. Block turquoise often has a slightly plastic feel and a too-perfect color. Both should be clearly disclosed as reconstituted or block.

7. Chrysocolla

Verdict: Not turquoise. A different copper-based blue-green mineral.

Chrysocolla is a hydrated copper silicate that produces vivid blues and greens often mistaken for turquoise. It is its own distinct mineral and worthwhile in its own right. The confusion is understandable because both stones contain copper and both can produce striking blue-greens. Chrysocolla is generally softer than turquoise.

Tell: Chrysocolla tends to be brighter and more electric in color than turquoise. It is also more porous and softer, so it cracks more easily without stabilization.

8. Larimar

Verdict: Not turquoise. A rare blue stone from the Dominican Republic.

Larimar is a blue variety of pectolite found only in the Dominican Republic. It produces soft sky-blue to deep ocean-blue colors that can superficially resemble turquoise but the stones are mineralogically distinct. Larimar is properly disclosed by name in the jewelry market and is not sold as turquoise by reputable sellers.

Tell: Larimar has characteristic white cloud-like inclusions and a softer, more oceanic blue than American turquoise. The geological origin (Dominican Republic, single small deposit) is a clear differentiator.

What to ask before you buy

If you are unsure whether you are looking at real turquoise or one of the stones above, ask the seller these six questions before you buy:

1. What is the specific mine or deposit?

2. Is the stone natural, stabilized, color-enhanced, or reconstituted?

3. If not turquoise, what mineral is this?

4. Who cut the stone?

5. Who set the silver?

6. Is the silver stamped 925 or Sterling?

A reputable seller will answer all six clearly. Vague answers are a signal to be careful.
