Quick answer
Amazonite is the blue-green variety of microcline feldspar, usually marked with natural white streaks of albite. Its colour comes from tiny traces of lead within the crystal structure. It rates 6 to 6.5 on the Mohs hardness scale and has cleavage, so it is reasonably hard but should be kept from sharp knocks and prolonged strong sunlight, which can lighten its colour.

Amazonite has a soft, watery blue-green that is hard to mistake once you know it, usually crossed by gentle white streaks. It is an affordable and popular stone for beads and jewellery, and it is also widely misunderstood, starting with its name. This guide takes a plain, factual look at what amazonite actually is, how to tell it from other green stones such as aventurine and turquoise, and how to care for it.
What is amazonite?
Amazonite is a blue-green variety of microcline, a potassium-rich feldspar. The gentle white streaks running through most pieces are not a flaw but natural albite, a white feldspar that grows intergrown with the microcline and follows its cross-hatched internal structure. That soft, striped look is one of amazonite's signatures.
Its blue-green colour was a puzzle for a long time. Modern analysis shows it comes from tiny traces of lead and water-related features within the crystal, rather than copper as was once assumed. The result is a colour that ranges from pale, milky green to a deeper blue-green.
The name is a curiosity in itself. Amazonite is named after the Amazon River, yet no notable amazonite deposits are actually known there, so the name is widely regarded as a misnomer, probably from confusion with another green stone. Today the main sources are Russia, the United States, Brazil, Madagascar and Ethiopia.
Amazonite, aventurine and turquoise
Amazonite is most often mixed up with green aventurine and, at a glance, with turquoise. The differences are easy once you know what to look for. Amazonite is a fairly opaque blue-green with soft white streaks and no sparkle, and it tends to block light rather than glow. Green aventurine is a quartz with a gentle glittery shimmer from mica flakes, and it is often more translucent.
Turquoise is the closest in colour, but it is a different, copper-bearing mineral and usually shows a brown or black matrix rather than amazonite's white feldspar streaks. Amazonite is rarely dyed, but it is occasionally colour-enhanced, so a piece that is unnaturally vivid, perfectly uniform and completely without white streaks is worth a question to the seller.

How hard is amazonite, and does it fade?
At 6 to 6.5 on the Mohs scale, amazonite is reasonably hard, but as a feldspar it has cleavage, meaning it can split cleanly if knocked sharply. Its colour is also sensitive to strong light and heat. A few habits keep it at its best:
- Rinse briefly, do not soak. A quick wipe with a soft, damp cloth is enough; avoid leaving it in water for long periods.
- Keep it out of prolonged strong sunlight. Intense sun and heat can gradually lighten amazonite's colour, so avoid sunny windowsills and hot cars.
- Protect it from knocks. Because it can cleave, take care with rings and avoid banging it against hard surfaces.
- Avoid harsh chemicals and store it apart. Cleaners and strong dips can dull the surface, and a lined box or pouch prevents scratches.

Choosing amazonite jewellery
Amazonite's soft colour and gentle veining make it an easy, affordable stone to wear. A few pointers help you choose well:
- Enjoy the white streaks. Natural albite veining is part of amazonite's character, so an even, slightly varied pattern is a good sign.
- Be wary of unnatural colour. An overly bright, uniform blue with no streaking may be colour-enhanced, so ask the seller.
- Mind the cleavage. As a hardness-6 to 6.5 feldspar, it suits pendants, earrings and beads well, and rings with a little extra care.
- Check the polish. A smooth, silky finish and tidy drill holes point to careful workmanship.

What are the white streaks in amazonite?
They are natural albite, a white feldspar that grows intergrown with the blue-green microcline. The streaks follow the stone's internal structure and are a normal, identifying feature, not a flaw.
Is amazonite the same as turquoise or aventurine?
No. Amazonite is a feldspar; turquoise is a copper mineral and aventurine is a quartz. Amazonite is opaque with white streaks and no sparkle, which sets it apart from glittery aventurine and matrix-veined turquoise.
Does amazonite fade in sunlight?
It can. Its colour is tied to trace lead and structural features that strong light and heat can gradually weaken, so prolonged direct sunlight is best avoided to keep the colour fresh.
Can amazonite go in water?
A brief rinse is fine, but avoid long soaking, harsh chemicals and sharp knocks. As a feldspar with cleavage at 6 to 6.5 on the Mohs scale, it prefers gentle handling.
