Buyer’s Guide to Amethyst Gemstones

Amethyst is the purple variety of quartz, the mineral that makes up most of the sand on beaches around the world. Although quartz is common, making up 12 percent of the earth’s crust, crystals of amethyst with fine color are much more rare.

Treasured by the ancient Romans, amethyst was worn as a talisman to ward off the intoxicating powers of Bacchus. Amethyst comes from the Greek “amethystos” which means “not drunken.” That’s why amethyst symbolizes sobriety.

The legend of the origin of amethyst comes from Greek myth. Dionysus, the god of intoxication, was angry one day and created a tiger to take revenge on the next human that crossed his path. Along came unsuspecting Amethyst, a beautiful young girl on her way to the temple of the goddess Diana. When Amethyst asked Diana to protect her from the tiger’s claws, Diana turned her into a statue of pure quartz. Dionysus wept tears of wine in remorse at the sight of the statue of the innocent girl, staining the quartz purple.

Since the middle ages, Bishop’s rings have been set with amethyst as a symbol of piety and celibacy.

In the Brazilian town of Ametista do Sul, St Gabriel’s Church is decorated with 40 tons of amethyst crystals covering the walls. The baptismal font is crafted from a large amethyst geode.

The meaning of amethyst is peace and serenity. Buddhists believe that amethyst enhances the tranquility of meditation, making it the preferred choice for Tibetan rosaries even today.

The amethyst of the ancient world was probably mined in Sri Lanka and small deposits in Europe. In the 18th century fine amethyst was discovered in the Ural mountains in Russia. This historical deposit was known as “Siberian amethyst” and was said to be exceptionally fine with a dark purple color and rose-colored flashes. Even today, top quality amethyst is sometimes called “Siberian” even though the Russian deposit was mined out long ago.

Since early in the 19th century, most of the amethyst on the market has been mined in Brazil. Amethyst is mined across the country including in Marabá, Pau d’Arco, and Rio Grande do Sul. Uruguay and Bolivia also produce amethyst.

In the 1950s, deposits of amethyst were discovered in Zambia. Zambian amethyst has a medium dark purple with dark blue zones which add a depth to the color. Amethyst with an unusual pinkish purple color is found in Vietnam.

Small amounts of amethyst are also mined in Arizona at the Four Peaks mine in the mountains above Phoenix.

Amethyst, the traditional birthstone for the month of February, is available in a wide range of sizes and shapes, including very large sizes. An amethyst in the Smithsonian is more that 1000 carats. Amethyst geodes can be large enough to stand in.

Amethyst is a fairly durable gemstone with a hardness of 7 on the Mohs scale. Its facets will slowly wear down over the generations because the dust in the air is quartz too. Although amethyst’s color is stable, avoid exposure to high heat.

To keep your rings clean, don't wear them when applying lotion or creams or using cleaning products like cleanser. Store all your gemstone jewelry separately, especially when travelling, so gems and metal can’t scratch each other. Clean with mild dish soap: use a soft brush behind the stone where dust can collect.

The purple gem most similar to amethyst is purple sapphire. In fact, in the Middle Ages purple sapphire was called “Oriental amethyst,” and purple quartz was known as “Occidental amethyst.” Sapphire is much harder than amethyst, with a Mohs hardness of 9, and also more durable. But purple sapphire is more expensive than amethyst too because its much more rare. Fine large examples can be thousands of dollars per carat.

The most popular amethyst engagement ring style is a diamond halo ring with a pave band. Amethyst also looks lovely in vintage style engagement ring settings.
