Real vs Fake Turquoise: How to Tell the Difference

Why so much 'turquoise' isn't

Genuine natural turquoise is relatively rare and priced accordingly, so a huge share of affordable "turquoise" jewellery is actually dyed howlite or magnesite (cheap white stones that take blue dye well), reconstituted turquoise (ground-up bits bonded with resin), or simply plastic. None of that is a scam if it's priced and described honestly as fashion jewellery — but it helps to know what you have.

The price signal

The fastest tell is price. Real, untreated natural turquoise in a decent size is not cheap. If a large "turquoise" pendant costs a few dollars, it isn't natural high-grade stone — it's dyed, reconstituted or imitation. That's fine for a fashion piece; just calibrate your expectations to the price.

Look at the matrix

Natural turquoise usually has a "matrix" — the web of brown or black veining from the surrounding rock. On real stone the veining looks irregular and sits within the stone. Dyed howlite often has grey, spiderweb-fine veins that can look too uniform, and dye can pool darker in the cracks.

Simple at-home checks

Turquoise is a real mineral and feels cool and solid; plastic feels light and warms quickly in the hand. On an inconspicuous spot, a cotton bud with a little acetone (nail polish remover) can lift blue dye off dyed howlite — if colour comes off, it's dyed. Do this only on a piece you already suspect, as it can mark the stone.

Buying with confidence

For fashion western jewellery, dyed or reconstituted turquoise is completely reasonable and keeps prices accessible — the look is what you're after. Just buy it as what it is, and don't pay natural-stone money for a treated one. If a piece matters, ask the seller directly whether the stone is natural, stabilised, dyed or reconstituted.
