Amazonite Beads Guide: Peruvian, Mozambique and Brazilian Amazonite

Amazonite is the green to blue-green variety of microcline, a potassium feldspar, with a hardness of 6 to 6.5. Its color comes from traces of lead held in the crystal together with water, and the white streaks in most beads are thin layers of a second feldspar, albite. Names such as Peruvian, Brazilian and Mozambique amazonite tell you where the rough is said to come from and hint at a look: Peruvian is known for soft, fairly even aqua to sea green, Brazilian for brighter blue-green with bold white streaks. Here is how the origins compare, how to tell amazonite from its look-alikes, and how to care for it.

Our amazonite bead collection carries Peruvian and Brazilian amazonite alongside strands sold simply as amazonite, in rounds, rondelles, chips and faceted and novelty shapes.

What Is Amazonite?

Amazonite belongs to the feldspars, the most common mineral group in the earth's crust and the same family as moonstone, labradorite and sunstone. It grows in granite and especially in pegmatites, the coarse granite veins where crystals have room to grow large. The classic sources are the Ilmen Mountains near Miass in Russia and the Pikes Peak area of Colorado, where blue-green crystals grow beside smoky quartz, and it is also found in Brazil, Madagascar, Ethiopia and elsewhere.

The name points to the Amazon River, but no amazonite deposit has been found there, and it is unclear whether the green stones once traded from the Amazon region were amazonite at all.

What Gives Amazonite Its Color

For a long time copper was assumed to be the colorant, as it is in turquoise. Research by Hofmeister and Rossman, published in 1985, showed that the blue-green needs both lead and water bound into the feldspar structure, plus radiation from the surrounding rock over geological time, which changes the lead and creates the color. Other studies have also looked at rubidium, thallium and iron, and the current view is that several factors work together, with lead and water at the center. In practice this means the color runs through the stone rather than sitting on the surface, and strong heat can bleach it, so amazonite does not belong near a torch flame or in a kiln.

White Streaks, Grids and Flashes

Look closely at most amazonite and you will see white or cream streaks running in roughly parallel lines, sometimes crossing to form a grid or checkerboard. These are perthite intergrowths: as the original feldspar cooled, sodium-rich albite separated from the potassium feldspar in thin sheets, much as oil and vinegar separate in a dressing. Tilt a bead under a light and you may also catch a brief flash from a flat cleavage plane inside it. Both features are good signs of real amazonite, because dyes, glass and most look-alikes do not copy them well.

That same cleavage is amazonite's weak point. Feldspar splits cleanly along flat planes, so a sharp knock can chip a bead or crack it straight across even though the stone is fairly hard.

Amazonite by Origin

Origin names in the bead trade are not grades, and they are not standardized. They describe where the rough is said to come from and, loosely, a look, and color varies within any deposit. Here is what each name usually suggests and what our own listings show.

Peruvian Amazonite

Peruvian amazonite has a trade reputation for soft, pastel color with fairly light streaking. Our Peruvian listings range from soft aqua and minty green to sea green, teal and turquoise green, some nearly even and some with fine white veins. It is the origin to choose when you want a quiet, consistent strand, from tiny microfaceted 2 mm to 4 mm rounds to smooth 6 mm to 10 mm rounds.

Brazilian Amazonite

Brazilian amazonite is known for more contrast. Our Brazilian listings show blue-green to soft aqua with clear white streaks and patches, and some strands add touches of cream and tan, so every bead looks a little different. Try the smooth Brazilian rounds when you want that patterned look. We also carry a strand sold as Brazilian black amazonite, which its listing describes as cut from the dark charcoal to taupe parts of the Brazilian rough.

Mozambique Amazonite

Mozambique amazonite has a reputation for brighter, more saturated teal to blue, sometimes with more translucency than other origins. None of our current listings is sold under the Mozambique name.

Russian and Colorado Amazonite

Russia's Ilmen Mountains were long the best-known source, famous for deep green to blue-green stone with strong white stripes. Colorado is famous for crystal specimens, often paired with smoky quartz, and most of that material goes to collectors rather than bead cutters.

Amazonite Look-Alikes and How to Tell Them Apart

Dyed howlite is the look-alike you are most likely to meet. Look for color gathered in cracks and around the drill hole, and for dark, spidery veins instead of amazonite's pale streaks. Our post What Is White Turquoise? Don't Be Fooled, It's Just Howlite explains why howlite is so often dyed.

Chrysoprase is the other common mix-up, especially with the greener amazonites. Hold both up to a light: chrysoprase glows evenly from within, while amazonite stays mostly opaque and shows its streaks. African turquoise and green aventurine are easy to separate once you see them side by side.

Caring for Amazonite

At 6 to 6.5, amazonite is harder than window glass, so everyday wear will not scratch it easily. Its cleavage is the real concern: avoid hard knocks, and in bracelets that bump against tables, consider small metal spacers between beads. Store it apart from harder stones such as quartz.

Clean amazonite with lukewarm water, a little mild soap and a soft cloth. Skip ultrasonic and steam cleaners, which can open cleavage cracks, and avoid soaking it in acetone or other solvents. Keep it away from the high heat of soldering. Because amazonite contains traces of lead, don't put it in drinking water, and keep loose beads away from small children who might put them in their mouths.

Designing with Amazonite

Amazonite's cool blue-green pairs well with warm, soft colors. Try it with peach moonstone or sunstone for a seaside look, with white howlite or pearls for a clean, airy strand, or with smoky quartz and brown jasper for something earthier. It suits both silver and gold, and the patterned Brazilian material holds its own in simple designs where a few plain spacers let the streaks show.

Frequently Asked Questions

Is Peruvian amazonite real amazonite?

Yes. Peruvian amazonite is the trade name for amazonite sold as coming from Peru. Like any origin name, it describes a source and a typical look, soft aqua to sea green, not a different mineral.

Is amazonite blue or green?

Both. It ranges from pale aqua and sky blue-green through teal to mint and leaf green, often with white or cream streaks.

What is the difference between Peruvian and Brazilian amazonite?

In the trade, Peruvian is known for softer, more even color, and Brazilian for brighter blue-green with bold white streaks and patches. Individual strands vary, so judge by the photos of the strand you are buying.

Does amazonite chip easily?

It can. Amazonite has perfect cleavage, so a hard knock may chip or split a bead. It is well suited to necklaces and earrings and holds up in bracelets with a little care.

How can you tell amazonite from dyed howlite?

Dyed howlite has dark web veins and color that pools in cracks and drill holes. Amazonite has pale, roughly parallel streaks and may flash from flat cleavage planes when tilted.
