Magnesite

That fizz is the only easy way to tell the two apart.

Howlite has fine black spiderwebbing and magnesite has broader brown veins, and otherwise they do the same job, which is to be dyed and sold as turquoise. Magnesite fizzes in warm acid because it is a carbonate. That fizz is the only easy way to tell the two apart.

Most of it is wearing another stone's name.

Magnesium carbonate, mostly an industrial refractory mineral, and the second great blank canvas of the trade. Broad brown veins rather than howlite's fine black web, plus a fizz in warm acid that howlite will not give you. Most of it is wearing another stone's name.

Acid is the only easy separation, and magnesite fizzes.

The second blank canvas of the trade, dyed the same turquoise blue and sold the same way, with broad brown veins where howlite has fine black webbing. Acid is the only easy separation, and magnesite fizzes. When it goes green it gets sold as lemon chrysoprase.

Same job as howlite, different veins, same dye bath.

Same job as howlite, different veins: broad and brown instead of fine and black, and just as likely to come out of a dye bath. Magnesite is a carbonate, so warm acid fizzes on it while howlite does nothing, which is the only quick separation. Dyed green it becomes lemon chrysoprase.

Magnesite fizzes in vinegar. Howlite does not.

The vinegar test is the only easy separation from howlite: magnesite fizzes and howlite does not. Broader brown veining instead of fine black spiderweb, denser in the hand, and every bit as willing to be dyed turquoise. Industrially it lines furnaces. Ornamentally it wears other names.

The vinegar fizz is the only easy separation from howlite.

Two blank canvases hold up the fake trade, and this is the second one. Magnesite is a carbonate, so it fizzes weakly in vinegar where howlite does nothing at all, and that is the only easy separation. Both take dye deeply. Both spend their commercial lives wearing turquoise's name.

Both spend their working lives wearing another stone's name.

Magnesium carbonate, mostly an industrial refractory, and the trade's second blank canvas. Where howlite carries a fine black spiderweb, magnesite carries broader and sparser brown veining, and vinegar is the only easy way to tell the two apart. Both spend their working lives wearing another stone's name.

It usually turns up wearing another stone name.

The trade second blank canvas. Magnesium carbonate, dyed the same turquoise blue as howlite and sold under the same borrowed names, and the only quick way to separate the two is that magnesite fizzes weakly in vinegar while howlite does nothing at all.

Its retail job is wearing other stones' names.

It fizzes in warm dilute acid where howlite does nothing at all, which is the only easy way to separate the two. Broader brown veins rather than a fine black spiderweb. Its day job is industrial refractory work and its retail job is wearing other stones' names.

The vinegar fizz is the only easy way to separate them.

The other blank canvas. Where howlite has fine black spiderwebbing, magnesite has broader brown veins, and both get dyed and sold as turquoise at the same inflated price. The vinegar fizz is the only easy separation, since magnesite is a carbonate and howlite is not.

The fizz is the only easy way to tell them apart.

Broader brown veins rather than howlite's fine black web, and it fizzes in acid because it is a carbonate. That fizz is the only easy way to tell the two apart, which matters because both get dyed and sold as turquoise. Neither is.

Almost all of it is wearing another stone's name.

Broader brown veining than howlite, and a body dense enough to look like unglazed porcelain. It takes dye so deeply that a shallow scratch tells you nothing, so the test is vinegar: magnesite fizzes and howlite does not. Almost all of it is wearing another stone's name.

Magnesite is carried for calm, sleep and self-love. Magnesium carbonate, mostly an industrial refractory mineral, and the second great blank canvas of the crystal trade.. Tradition links it to the crown, heart chakra.

Like howlite, dyed magnesite is a standard turquoise substitute and is also sold as 'lemon chrysoprase' when dyed or nickel-stained green-yellow. Highly porous and takes dye deeply, so a shallow scratch may not reveal white — check drill holes and chipped edges.. The acid test separates it from howlite: magnesite is a carbonate and effervesces in warm dilute acid (weakly in cold vinegar), while howlite does not react at all. Both are soft and knife-scratchable, and both reveal white under the dye at a drill hole.. Like howlite, dyed magnesite is a standard turquoise substitute and is also sold as 'lemon chrysoprase' when dyed or nickel-stained green-yellow.

No. Magnesite dissolves or spalls in water. Dust it dry instead of soaking it, and keep it out of salt.
