Is turquoise on Amazon real?

Quick answerUpdated October 2026

Some turquoise on Amazon is real, but a cheap listing may not be natural turquoise at all: it can be dyed howlite or magnesite, "reconstituted" material that may hold no turquoise, or plastic or glass. Most real turquoise sold today is stabilised with resin or plastic, which is normal and should be disclosed. The listings worth a closer look name the mine, state the treatment and never call an imitation "synthetic".

What is cheap "turquoise" on Amazon usually made of?

What it is	Made of	What the FTC Guides say to call it	Clues
Dyed howlite or magnesite	Other minerals dyed blue. GIA lists dyed howlite among turquoise imitations, and a 1983 study in GIA’s journal found dyed magnesite, calcite and dolomite among imitations from the trade	"Imitation" or "simulated" turquoise, never plain turquoise	White at nicks and chips; colour may come off on an acetone swab; howlite is softer ( 3 to 3.5, against 5 to 6 for turquoise)
"Reconstituted" or "reconstructed" turquoise	In principle, finely powdered turquoise bound into a solid. In the same 1983 study, most trade samples sold as "reconstructed turquoise" held no turquoise at all: they were dyed, plastic-impregnated gibbsite	Not plain or "treated" turquoise: stone material held together by a filler or binder should be described so it is clear it differs from the named stone and needs special care; with no turquoise in it, it is an imitation	The description mentions powder, a binder, resin or "reconstituted"
Plastic, resin or glass	Man-made imitations; GIA names plastic and glass	"Imitation" or "simulated" turquoise, never "real", "genuine" or "natural"	The description names resin, acrylic, plastic or glass
Synthetic turquoise	Factory-made material that contains turquoise; the 1983 study called Gilson’s the only true synthetic then on the market	"Laboratory-created", "synthetic" or similar, only if it has essentially the same properties as turquoise	Hard to separate from natural turquoise with routine tests; a lab can do it
Stabilised turquoise	Real mined turquoise impregnated with resin or plastic to harden it; the International Gem Society says almost all but the finest turquoise is treated this way	Turquoise, with the treatment disclosed	Real turquoise; should cost less than comparable untreated stone
Untreated turquoise	Mined turquoise good enough to cut and wear without impregnation	Turquoise	Rarer, and should cost more than comparable stabilised stone

How can you tell if turquoise is real or howlite?

No home test proves a stone is turquoise. Gem labs use instruments such as and X-ray diffraction, and the 1983 study in GIA’s journal found that routine gem tests struggle to tell natural, treated, synthetic and imitation turquoise apart. Four checks can still flag cheap imitations. Look where the surface is broken. Howlite is naturally white, and a jewellery trade article on turquoise notes that the surface dye on these imitations is often revealed by small nicks and chips, so white showing at a nick, a chip or the edge of a drill hole is a strong warning sign. No white does not prove the stone is turquoise. Look at the cracks with a loupe. A 2015 report in GIA’s journal on a dyed turquoise sphere found the colour concentrated in its cracks and cavities, so lines of stronger colour along cracks point to dye. Try an acetone swab, carefully. GIA notes that many dyes come off with a solvent such as alcohol or acetone. Rub a cotton bud dipped in acetone quickly on a hidden spot, then wipe the stone clean. Blue on the bud means the stone is dyed, which can be dyed turquoise as well as dyed howlite; a clean bud proves nothing, because not every dye comes off. GIA also says plastic impregnations in turquoise stay durable only if kept away from heat and chemicals, so save this test for cheap pieces you already doubt. Read the price and the words together. GIA says turquoise prices depend on the colour, the matrix and whether the stone is treated, so a long strand of bright, even blue beads at a costume-jewellery price, with no mine and no treatment named, deserves suspicion.

What is stabilised turquoise, and is it real?

Yes, stabilised turquoise is real turquoise. GIA’s turquoise buying guide calls natural turquoise porous, warns that chemicals in cleaning products, perfume and cosmetics can affect its colour, and says it absorbs skin oil, which darkens it. Stabilising impregnates the stone with a resin or plastic that hardens it, darkens light colours and lets porous, chalky material be cut at all; the 1983 study in GIA’s journal reported that good-quality turquoise was being stabilised too, to make it more durable. The International Gem Society says almost all but the finest turquoise is impregnated this way. GIA says turquoise is commonly treated and that all treatments should be disclosed, and it calls plastic impregnations in turquoise durable as long as they are kept from heat and chemicals. Whether a stone is treated is one of the things GIA says drives turquoise prices, so stabilised stone should cost less than comparable untreated stone. Do not read silence as "untreated": the 1983 study noted that paraffin treatment, for one, was not always disclosed when turquoise was sold.

What do "synthetic", "reconstituted" and "genuine" mean on a turquoise listing?

Synthetic, laboratory-created or created should mean a factory-made material with essentially the same properties as turquoise. Such material exists: the 1983 study in GIA’s journal named Gilson’s synthetic, which contains crystalline turquoise, as the only true synthetic then on the market, while noting that many imitations were also being called turquoise. US guidance does not allow "synthetic turquoise" for dyed howlite, magnesite or resin, which are not turquoise at all; the right words for those are "imitation" or "simulated". Stabilised means real turquoise hardened with resin or plastic. Reconstituted or reconstructed should mean finely powdered turquoise bound into a solid, which is how the 1983 study describes the true product, but its tests found most trade samples under that name held no turquoise. Genuine, real or natural should not be used for anything manufactured or produced artificially, but none of them tells you whether the stone was stabilised; look for the word "untreated" or ask. For the rest of a listing’s vocabulary, see how to read an Amazon gem listing.

What does US law say a turquoise listing must disclose?

The Federal Trade Commission’s Jewelry Guides (16 CFR Part 23) set out how US sellers should describe gems. Calling something plain "turquoise" when it is not mined turquoise is deceptive (23.25(a)), and an imitation should carry "imitation" or "simulated" right before the stone’s name (23.25(b)). On "synthetic", section 23.25(c) says: "It is unfair or deceptive to use the word ‘laboratory-grown,’ ‘laboratory-created,’ ‘[manufacturer name]-created,’ ‘synthetic,’ or other word or phrase of like meaning with the name of any natural stone to describe any industry product unless such product has essentially the same optical, physical, and chemical properties as the stone named." A product of stone material with a filler or binder should not be called plain or "treated" turquoise unless the description makes clear that it lacks the named stone’s characteristics and needs special care (23.25(d)), and words such as "real", "genuine" and "natural" should not describe anything manufactured or produced artificially (23.27). On treatment, section 23.24 says: "It is unfair or deceptive to fail to disclose that a gemstone has been treated if" the treatment is not permanent, creates special care requirements, or has a significant effect on the stone’s value. For goods bought online, that disclosure "should be made in the solicitation for, or description of, the product." The Guides are the FTC’s current thinking on what is deceptive under the FTC Act and do not bind sellers in themselves, but the FTC can take action against a claim that is inconsistent with them.

Which turquoise listings are easier to trust?

Listings that make specific claims: the mine, the treatment (stabilised or untreated), the metal and, for Native American work, the maker. A mine name is not a guarantee, and GIA notes that turquoise is priced mainly on quality rather than origin, but a specific claim is easier to check, and gives you something to point to if the piece is not as described. Our turquoise page includes pieces whose listings name the mine, such as Sleeping Beauty or Kingman turquoise from Arizona, or the Navajo maker. For what each treatment means for care and value, see gem treatments explained.

Frequently Asked Questions

Is howlite turquoise real turquoise?

No. Howlite is a different, naturally white mineral that is often dyed blue to look like turquoise. A name such as "howlite turquoise" describes howlite, and under the FTC Guides an imitation should be called "imitation" or "simulated" turquoise.

Is stabilised turquoise fake?

No. It is real turquoise hardened with resin or plastic, and almost all but the finest turquoise is treated this way. The treatment should be disclosed, and stabilised stone should cost less than comparable untreated turquoise.

Is synthetic turquoise real turquoise?

It is not natural turquoise. Under the FTC Guides, "synthetic turquoise" should only describe a man-made product with essentially the same properties as turquoise, and a 1983 study in GIA’s journal described one, Gilson’s. Dyed howlite, magnesite, resin or glass sold as "synthetic turquoise" are imitations.

How should I clean and wear turquoise?

GIA advises putting turquoise on after sunscreen, lotion, make-up and hairspray, taking it off before using household cleaners, cleaning it only with mild soapy water, and never putting it in an ultrasonic or steam cleaner. It absorbs skin oil, which darkens its colour.
