Nontronite, an iron-rich member of the smectite clay group. The olive to chartreuse green comes from iron substituted into the clay structure itself.

Where does it come from?

Minas Gerais, Brazil, through a community partnership with small-scale miners we have worked with for years.

What are the exact dimensions?

2.22 inches long by 2.59 inches wide by 1.97 inches high, 56 grams. This is the exact piece pictured.

Untreated. The color and the chalky botryoidal texture are exactly as the specimen came out of the ground.

How soft is it really?

Mohs 1 to 2, softer than a fingernail. Lift it by the base, never wash it, and keep it out of humid rooms.

What is nontronite traditionally associated with?

Grounding, earth connection, and patient transformation. Nontronite has no deep historical lore, and we would rather say that plainly than invent one.

What does a crystal grade (A, AA, or AAA) actually mean?

Crystal grades reflect visual quality within a single batch. Grade A is standard quality with typical inclusions. Grade AA shows stronger color saturation, cleaner surface, and tighter sizing. Grade AAA represents the top 10 to 15 percent of any batch: exceptional clarity, consistent color, and minimal surface variation. At Beyond Bohemian, grades are assessed by Paul Oliver at point of purchase.

Will I receive the exact piece shown, or one chosen from your stock?

For bulk listings sold by weight or piece count, you receive pieces from the same batch shown in the photos. Each piece is hand-selected at the time of packing. For unique specimens listed individually, you receive the exact piece photographed. The listing will specify which applies.

How do I know this crystal is ethically sourced?

Beyond Bohemian traces each stone as far up the supply chain as possible and is transparent when that tracing has limits. We work with small-scale operations and family-run suppliers wherever we can verify fair compensation. You can ask about any specific piece and we will tell you what we know and what we do not.

What is the return policy?

Beyond Bohemian accepts returns within 90 days of purchase. Items must be in original condition. Return shipping is the responsibility of the buyer. Contact us before returning so we can confirm eligibility and provide instructions.

Size: 2.22" L x 2.59" W x 1.97" H

Nontronite is a rare iron-rich smectite clay mineral in the phyllosilicate family, prized by mineral collectors for its vivid chartreuse-to-olive-green coloration and soft, chalky botryoidal surface texture. It forms through the hydrothermal alteration of iron-bearing rocks, typically in oxidized zones of nickel and iron deposits. With a Mohs hardness of just 1 to 2, it ranks among the softest collector minerals available, handled as a museum-quality specimen rather than a working stone. Collector-grade material from Minas Gerais, Brazil is especially sought for its saturated color and unusually well-preserved botryoidal structure. These are genuinely rare stones in the collector market, particularly at this size and color quality.

Nontronite is a deeply grounding stone, rooted in Earth energy and connected to both the Root and Solar Plexus chakras. It is associated with themes of transformation, endurance, and elemental stability, a reminder that profound structures take time and pressure to form. Crystal practitioners work with it for grounding during periods of upheaval, stabilizing energy in spaces that feel energetically scattered, and deepening connection to the natural world. Its rare, collector-quality nature makes it a meaningful piece for those drawn to working with unusual Earth energies.

These are traditional associations drawn from historical practice. This stone is not a substitute for medical or mental health care.

Care & Use Sensitivity: Very High. Nontronite is a clay mineral, so it absorbs water, oils, and atmospheric humidity readily. Any moisture can alter its texture and color permanently.

Best For

Display and collection. Not recommended for crystal grids, pockets, or regular handling.

Care

Dust gently with a soft, dry natural-bristle brush if needed. Store in a dry, stable environment away from direct sunlight, since UV exposure can bleach the color over time. A display case or enclosed box works well.

Avoid

All water, steam, oils, prolonged humidity, ultrasonic cleaners, and any liquid exposure. Never submerge or mist.

Cleansing

Moonlight, sound, or visualization only. No water, salt, or earth burial.

Charging

Brief indirect sunlight or moonlight. Sound bowls are ideal for this stone.
