📖 Etymology

Mansfieldite is named in honour of George Rogers Mansfield (1875–1947), a geologist of the United States Geological Survey. It joins the long tradition of arsenate and phosphate minerals named for the scientists who studied the ground they came from.

Hardness (Mohs)

Mansfieldite is a hydrated aluminium arsenate, AlAsO4·2H2O, the aluminium-dominant member of a series with scorodite (its iron counterpart). Orthorhombic in symmetry, it forms crusts, earthy masses and small crystals, white to grey, pale yellow or with delicate blue and green tints, with a moderate hardness of about 3.5–4.

It is a secondary mineral, born in the oxidised zones of arsenic-bearing ore deposits where arsenic, aluminium and water combine. Where iron takes the place of aluminium it grades into scorodite, the two forming a continuous family.

🌍 Discovery & Origin

Mansfieldite was described in the mid-twentieth century, with its type locality at Hobart Butte in Lane County, Oregon, USA. It has since been recognised at oxidised arsenic-bearing deposits in several countries.

It is an uncommon mineral, found as crusts and aggregates in the weathered upper zones of ore bodies, and known to collectors in pale white, yellow, blue and green specimens.

Toxic Mineral

Contains arsenic — do not ingest, lick, or make crystal water or elixirs from this mineral. Arsenate compounds are poisonous.

It can form soft, powdery crusts, so wash hands after handling, do not grind or inhale its dust, and keep it away from children and pets.

Interesting Facts

  • 1 Mansfieldite is the aluminium analogue of scorodite, the two forming a continuous series as aluminium and iron substitute for one another.
  • 2 It is a secondary arsenate, forming when arsenic-bearing ores weather and oxidise near the surface.
  • 3 Its type locality is Hobart Butte in Oregon, USA, where it was first recognised and described.
  • 4 Though usually pale, it can take on soft blue and green tints, and is an uncommon species sought by collectors of arsenate minerals.

💎 What Makes It Unique

💧
Aluminium Twin of Scorodite

The aluminium-rich end of the scorodite series — the same hydrated arsenate, with aluminium in place of iron.

Pale, Sometimes Blue

White to grey or yellow, it can carry delicate blue and green tints in its crusts and crystals.

Born of Weathering

A secondary mineral of oxidised arsenic deposits — formed as older ores break down and are cleansed into new form.

🌙 Spiritual

"Real happiness lies in making others happy."

Mansfieldite is a high-frequency stone — its frequency is very high and reaches the Soul Star, the centre that sits above the body's seven chakras and works at the subtlest, deepest level of all. Crystals that vibrate this high reach beyond surface troubles toward old, buried imprints — the deep memories of grief, trauma and sorrow that need clearing for a person to become truly free.

This is, above all, a stone of Cleaning. Just as the mineral itself is born when older ore is weathered and washed into a purer form, so it works to dissolve what has gone stale and heavy at the soul level. Because its high frequency dissolves the finest, subtlest layers, it reaches close to the root of an issue rather than only its outer edge — a quiet washing-through with grace-light, gentle in power yet far-reaching in depth.

"If your thoughts are rooted in love and integrity, only goodness will follow you."
— Vallalar

And it carries Love, Life and Joy: what it clears away it replaces with light, so the cleansing does not leave a person empty but renewed, warmed and gladdened. As an Expanding and Frequency stone, it lifts and widens the whole field, opening the higher centres — though, being arsenic-bearing, it is to be worked with only by presence and never taken inwardly in any form.
