Why is amethyst so affordable if it was once a "precious" stone?

Huge, high-quality deposits in Brazil, Uruguay, and Africa turned a once-scarce gem into an abundant one. The beauty did not change — the supply did. It is arguably the best saturated-purple value in fine jewelry.

Is amethyst the same mineral as citrine?

Yes — both are quartz. Citrine is usually amethyst that has been heated (naturally or in a kiln) until the purple turns golden. A stone with both colors in one crystal is sold as ametrine.

Some amethyst can fade with long, intense light or heat exposure. Normal wear is fine; just avoid baking it in a sunny window for years. Color loss, when it happens, is gradual.

Amethyst

Amethyst is the purple variety of quartz, colored by iron and natural irradiation. For most of history it sat alongside ruby, emerald, and sapphire as a “cardinal” gem — until vast deposits were found in Brazil and Uruguay in the 1800s and the price collapsed. What was once a stone of kings is now one of the best values in color: deep, saturated violet for a fraction of any comparable gem.

Mohs hardnessAmethyst · 7 / 10

Everyday wear comfortably wants a 7+. Below 7, choose settings that protect the stone (bezel, halo) and store the piece carefully.

At Mohs 7 it is the same hardness as every other quartz, which is to say hard enough for daily wear but soft enough to scratch over years of hard use. It is February’s birthstone and the traditional sixth-anniversary gift.

The most prized amethyst is a deep, slightly reddish 'Siberian' purple with flashes of red and blue. Paler 'Rose de France' lavender is gentler and more affordable.

Treatments

Most amethyst is untreated. Some pale material is gently heated to deepen color, and — notably — heating amethyst is how most citrine is made: the same mineral, the purple driven over to golden yellow. Heat is stable and permanent. Be aware that synthetic amethyst exists and is common in mass-market jewelry; we disclose natural versus lab-grown.

Daily wear

Amethyst wears well in every piece. Its one quirk: prolonged, intense sunlight or heat can fade some stones over time, so it is happiest as an everyday ring or pendant rather than something left in a sunny window. Any metal suits it; white metals keep the purple cool, yellow gold adds warmth.
