How Amethyst Forms
A journey millions of years in the making
- 01
Volcanic Activity
Amethyst begins its formation in volcanic rock cavities called geodes. As lava cools, gas bubbles become trapped, creating hollow pockets that will eventually house amethyst crystals.
- 02
Silica-Rich Solutions
Over time, groundwater carrying dissolved silica (silicon dioxide) seeps into these cavities. The water also carries trace amounts of iron and other minerals essential to amethyst's formation.
- 03
Crystal Growth
Under specific temperature and pressure conditions, silica molecules begin to crystallize on the cavity walls. This process occurs over millions of years, layer by layer, forming the characteristic hexagonal crystal structure.
- 04
The Purple Magic
The distinctive purple color emerges when iron impurities within the crystal structure are exposed to natural gamma radiation from surrounding rocks. This irradiation changes the oxidation state of iron, creating the violet hues we cherish.
Each amethyst crystal is a time capsule, preserving millions of years of Earth's geological history.
04
Meaning & Symbolism
The stone of spiritual wisdom
01
Sobriety & Clarity
The name "amethyst" derives from the Greek "amethystos," meaning "not intoxicated." Ancient Greeks believed the stone protected against drunkenness and promoted clear thinking.
02
Spiritual Protection
Associated with the crown chakra, amethyst is believed to enhance spiritual awareness, intuition, and psychic abilities while providing protection against negative energies.
03
Inner Peace
In crystal lore, amethyst is traditionally called a stone of calm, and many keep it near the bedside. These are traditional associations rather than proven effects.
04
Royalty & Nobility
Throughout history, purple has been the color of royalty, and amethyst adorned the crowns and jewelry of monarchs. It symbolizes power, luxury, and noble character.
05
A Royal History
3000 BCE
Ancient Egypt
Egyptian royalty wore amethyst jewelry and carved it into amulets. The stone was believed to protect against evil and was placed in tombs of pharaohs.
800 BCE
Ancient Greece
Greeks created amethyst drinking vessels, believing the stone would prevent intoxication. The tale of Dionysus and the maiden Amethyst came much later, from a French poem of 1576.
500–1500 CE
Medieval Europe
Amethyst became a symbol of royalty and was reserved for the highest ranks of the Catholic Church. Bishops' rings traditionally featured amethyst, symbolizing piety.
1800s
British Royal Jewels
Queen Charlotte and later Queen Victoria cherished amethyst jewelry. The Kent Amethysts remain with the British royal family, and the so-called Delhi Purple Sapphire, in fact an amethyst, is held at London's Natural History Museum.
Today
Modern Era
Now accessible to all, amethyst remains one of the world's most beloved gemstones. It's the official birthstone for February and continues to symbolize wisdom and spirituality.

Caring for Your Amethyst
Preserve its beauty for generations
Do
- Clean with lukewarm water and mild soap
- Use a soft brush for settings and crevices
- Store separately in a soft pouch
- Remove before physical activities
- Have settings checked annually
Avoid
- Prolonged direct sunlight (causes fading)
- Extreme temperature changes
- Ultrasonic and steam cleaners
- Harsh chemicals and perfumes
- Contact with harder gemstones
Important Note
Amethyst can fade with prolonged exposure to strong light. Store your pieces in a cool, dark place when not being worn to preserve their vibrant purple color.

Against Sameness
The range of pale purple, and pinks to medium to dark purple to green purple all sit nicely in the spectrum of color palettes I use.
It started at the Tucson Gem Show in Tucson, Arizona, where I found a strand of Brazilian amethyst so unusual it stopped me mid-aisle. The clarity and cut are the two main characteristics required to stop me in my tracks when perusing a table full of trays of gemstones. I used to buy one-off strands simply for their beauty before I began designing cohesive collections. So what began as buying for the sheer visual appeal now needs to be part of a greater narrative and belongingness to a body of work contained within a collection.
I tend to always reach for lighter and paler shades of purple amethyst because they blend more seamlessly into a palette of other colors. In daylight a pale stone sends its light back out of the facets, what gemologists call brilliance, and it flickers as it moves, which they call scintillation. Deep saturated hues of purple amethyst are so specific and rule its color class all on its own, that it either shines on its own or demands equally strong and jewel toned counterparts to match the boldness of character deep purple amethyst embodies. Indoors, the deepest stones can close up and read almost black, what gemologists call extinction.
I am always drawn to green amethyst. Something about the clarity and color of the stones I discover regularly catches my eye at the gem shows. I've never seen such a variety of gem cuts either and in all sizes, two characteristics that are critical to creating visual interest to my work. Sameness in gemstones translates to sameness in my clusters which would lead to sameness in my overall design aesthetic. This is something I'm actively looking to avoid when comparing strands to purchase at gem shows.
Sameness in gemstones translates to sameness in my clusters.
Amethysts are more friendly to work with than most other stones because they are durable, rarely cracking or splitting even while reaming bigger holes with a diamond drill bit. Whatever design I land on has to work with the hole placement and how they will be attached in the final design. Throughout my career, I've designed with amethyst in vastly different ways. One celebrates amethyst's natural irregularity; the other highlights its ability to be precisely faceted and aligned.
Janet once described the experience of wearing my work in a way I have never forgotten. She said you feel the stones. First they feel cold against your skin. Then they warm to your body temperature.

What is amethyst?
Amethyst is the purple variety of quartz, colored by traces of iron and natural irradiation. It ranges from pale lilac to deep royal purple, has a Mohs hardness of 7, and is durable enough for everyday wear.
What does amethyst mean?
The name comes from the Greek amethystos, "not intoxicated": ancient Greeks believed the stone guarded against drunkenness. In crystal lore, amethyst is traditionally called a stone of calm and clarity; these are traditional associations rather than proven effects. For Andrea it means range: "The range of pale purple, and pinks to medium to dark purple to green purple all sit nicely in the spectrum of color palettes I use." She chooses each stone by eye.
How does amethyst form?
Much of the world's amethyst grows inside hollow pockets in volcanic rock, called geodes, where silica-rich groundwater lays down quartz crystal over millions of years. Traces of iron in the crystal, exposed to natural radiation from the surrounding rock, turn it purple. The strand that started Andrea's amethyst work was Brazilian amethyst she found at the Tucson Gem Show.
How do I care for amethyst?
Clean it with warm soapy water and a soft brush. Keep amethyst out of long, direct sunlight, which can slowly fade its purple over time, and avoid steam and ultrasonic cleaning.
What stones does Andrea pair with amethyst?
Her amethyst pieces often bring in pink amethyst and fancy-cut ametrine briolettes alongside high-luster GIA certified pearls, set in 14k gold-filled with 24k gold vermeil details, so the purple has warmth and light around it.
Can I commission an amethyst piece?
Yes. Every piece is one of a kind, so Andrea can build a design around the shade of amethyst you prefer. Start a commission at andreali.com/custom-shop.
