Prasiolite · One-of-a-Kind · Handcrafted in Denver

Green amethyst — properly known as prasiolite — is one of the rarest forms of quartz on earth. Its delicate sage-to-olive hues emerge when iron-bearing amethyst meets volcanic heat deep underground, a transformation millions of years in the making. Natural prasiolite is exceedingly rare; most of what exists in the world comes from Brazil's Minas Gerais region. I source each stone individually, selecting for depth of color, clarity, and the subtle green fire that makes prasiolite unlike any other gemstone in my studio.

There's something about green amethyst that stops people mid-sentence. It's not loud. It's not trying to compete with emerald or peridot. It's this quiet, sophisticated green that catches light in a way that makes you look twice — and then you can't stop looking.
— Andrea Li, designer

Why I Work with Prasiolite

Prasiolite sits in a color space that almost no other gemstone occupies — cooler than peridot, warmer than green tourmaline, softer than emerald. It pairs beautifully with both gold and silver, and it has enough transparency to let light pass through in a way that feels alive on the skin. Every piece I create with it is one-of-a-kind because no two prasiolite stones carry the same depth of green.

Amethyst's Green Secret

Most people know amethyst as purple. What they don't know is that when certain iron-bearing amethyst meets intense heat — either from volcanic activity or careful treatment — the crystal transforms from violet to this ethereal green. It's the same mineral, the same structure, but with a completely different personality. That transformation is part of what makes it special.

Caring for Your Green Amethyst

☀️
Avoid prolonged sunlight Extended direct sun exposure can gradually fade the green color. Store in a jewelry box or pouch when not wearing.
🧼
Clean gently Warm water, mild soap, and a soft brush. Avoid ultrasonic cleaners and steam — heat can affect color stability.
💎
Durable for daily wear At 7 on the Mohs scale, prasiolite is suitable for everyday jewelry. Harder than most glass and steel.
🧴
Put jewelry on last Apply perfume, lotion, and hairspray before putting on your piece. Chemicals can dull the stone's surface over time.

Frequently Asked Questions

About Green Amethyst & Prasiolite Jewelry
Is green amethyst the same as prasiolite? +

Yes — prasiolite is the gemological name for green amethyst. Both are quartz colored by iron impurities, but where standard amethyst gets its purple from irradiation, prasiolite's green emerges when specific iron-bearing amethyst meets intense heat. While "green amethyst" is the more familiar term, gemologists prefer "prasiolite" because by strict definition, amethyst is purple. I use both names because most people searching for this stone know it as green amethyst.

Is natural prasiolite rare? +

Extremely. Natural prasiolite was first discovered in the early 1800s in Silesia, Poland, and only a handful of natural deposits exist worldwide — including Bahia, Brazil; Thunder Bay, Canada; and Namibia. Most prasiolite on the market is produced by carefully heating amethyst from Brazil's Minas Gerais region to approximately 500°C, which converts the purple to green. This heat treatment is stable, permanent, and an accepted practice in the gemstone industry.

Will the green color fade over time? +

With normal wear, no. The green color is stable and won't fade from everyday use. However, prolonged exposure to intense direct sunlight — like leaving your piece on a sunny windowsill for weeks — can gradually lighten the color. Store your green amethyst jewelry in a pouch or jewelry box when you're not wearing it, and you'll preserve the color indefinitely. This is similar to how you'd care for any fine gemstone.

Can I wear green amethyst jewelry every day? +

Absolutely. Prasiolite ranks 7 on the Mohs hardness scale — harder than glass, steel, and most everyday materials that could scratch it. It's an excellent choice for rings, necklaces, earrings, and bracelets you plan to wear regularly. Just follow the basic care guidelines: apply perfume and lotion before putting on your jewelry, clean with warm soapy water rather than ultrasonic cleaners, and store it separately to prevent scratching from harder gemstones like diamonds or sapphires.

How is green amethyst different from peridot or emerald? +

They're all green, but the resemblance ends there. Emerald is a beryl mineral — much softer (7.5–8 Mohs, but often with inclusions that make it fragile) and dramatically more expensive. Peridot is an olivine mineral with a warmer, more yellow-green tone. Prasiolite sits in a cooler, more sophisticated sage-green space with exceptional clarity and transparency. It's also significantly more affordable than emerald, making it perfect for statement pieces where you want size and presence without the five-figure price tag.

What metals pair best with green amethyst? +

Green amethyst is remarkably versatile with metals. In my studio, I most often set prasiolite in 14k gold — the warm yellow gold creates a beautiful contrast that brings out the green's earthy depth. Rose gold adds a romantic warmth. Sterling silver or white gold lean the stone cooler and more contemporary. There's no wrong answer; it depends on your personal style and skin tone. That said, gold is my go-to because it makes the green absolutely glow.

Is green amethyst a February birthstone? +

Since prasiolite is a variety of amethyst, it shares the February birthstone connection. If you love the idea of a February birthstone but want something beyond the traditional purple, green amethyst is a perfect alternative. It carries the same quartz family heritage and metaphysical associations with clarity and calm, but with a distinctly different personality.
