Feldspar crystal

Feldspar is less a single stone than a whole family — the most abundant mineral group in the Earth's crust, and the parent of several of the most-loved crystals we carry. Moonstone, labradorite, amazonite, and sunstone are all feldspars; what looks like four very different stones is really one mineral group wearing four faces. We treat feldspar here as that parent: the thread that ties the shimmer of moonstone, the flash of labradorite, the green of amazonite, and the glow of sunstone back to a common origin.

Across its varieties, feldspar is a stone of light moving through structure — labradorescence, adularescence, the schiller glow — and in crystal tradition that play of light reads as perception, transformation, and seeing what was always there. Chemically it is an aluminosilicate of potassium, sodium, and calcium, with a Mohs hardness of 6 to 6.5. If you're drawn to a stone that shifts as you turn it, you're almost certainly drawn to a feldspar.

Living with the stone

How to use Feldspar

  • Carry or wear the variety whose theme you're working with — moonstone for a season of change, sunstone for a flat week, amazonite before a hard conversation.
  • Meditation: hold a flashing labradorite or moonstone at the brow and let the moving light hold your attention; it's a natural focus point.
  • Bedside: moonstone is a traditional companion for dreamwork and gentler sleep.
  • Workspace: amazonite near where you write or speak; sunstone where you want warmth and momentum.
  • Turn it in the light. Feldspar's phenomena only appear at certain angles — handling the stone is part of the practice, not incidental to it.

Pairings

Crystal combinations

  • Feldspar + Clear Quartz: quartz lends amplification to feldspar's clarity-of-seeing.
  • Moonstone + Labradorite: a classic intuition-and-transformation pairing for inner work and dreams.
  • Amazonite + Blue Lace Agate: doubles down on calm, honest throat-chakra communication.
  • Sunstone + Carnelian: warmth, confidence, and creative drive.
  • Labradorite + Black Tourmaline: transformation paired with grounded protection.

Keep it well

Care & cleansing

At Mohs 6 to 6.5 with two good cleavage planes, feldspars are more fragile than quartz and can chip or split along the cleavage if knocked. Handle with reasonable care.

  • Cleansing: brief running water is generally fine; dry promptly. Moonlight is a fitting and gentle choice for the whole family, moonstone especially.
  • Avoid: prolonged soaking, harsh chemicals, ultrasonic cleaners, and hard knocks. Some feldspars (notably amazonite and sunstone) can fade or dull with very long, direct sun exposure, so don't store them in a hot window.
  • Recharging: moonlight, or rest on a quartz cluster.

Buy with confidence

Buying guide

You'll almost always shop feldspar by its variety name — moonstone, labradorite, amazonite, sunstone — rather than as "feldspar," and that's the right instinct. A few honest pointers:

  • Look for genuine phenomena. Real labradorescence shifts as you move the stone; real moonstone adularescence floats inside the stone rather than sitting on the surface. Flat, painted-looking "flash" is a warning sign.
  • Amazonite is sometimes confused with dyed howlite or reconstituted material; true amazonite shows fine white microcline streaking. We sell amazonite as the natural microcline it is.
  • Sunstone has a natural glittery schiller; uniformly sparkly orange glass ("goldstone") is a manufactured imitation, not sunstone.
  • Every feldspar we carry is a real, quality-verified stone. In 14 years serving the community we've built our name on never substituting a dyed or synthetic look-alike for the genuine mineral.

Questions about Feldspar

Is feldspar a crystal or a rock?

It's a mineral group — the family of aluminosilicate minerals that includes moonstone, labradorite, amazonite, and sunstone. It's also the most abundant group in the Earth's crust, so it's a major component of many rocks, but the gem varieties are true crystals.

What is the difference between moonstone and labradorite?

Both are feldspars, but moonstone is usually an alkali feldspar (orthoclase/adularia) with a soft floating blue-white sheen called adularescence, while labradorite is a plagioclase feldspar with a bolder blue-to-gold flash called labradorescence. Same family, different internal structure.

Is feldspar safe in water?

A brief rinse is generally fine, but feldspars are softer than quartz (Mohs 6–6.5) and have cleavage planes, so we recommend against long soaking and never use ultrasonic cleaners. Dry promptly.

Which feldspar should I choose?

Match the variety to your intention: moonstone for new beginnings and intuition, labradorite for transformation and protected energy, amazonite for truth and communication, sunstone for warmth and vitality.

Is amazonite really found in the Amazon?

The name is historic and a bit of a misnomer — the green stones originally found near the Amazon River were probably a different mineral. True amazonite is a green variety of microcline feldspar, mined today mainly in Russia, Madagascar, and the USA.
