Mimetite is a lead arsenate chloride mineral formed as a secondary deposit in the oxidized zones of lead deposits, usually as small hexagonal prisms. The color varies from pale to bright yellow, to orange to brown, even gree or white.   The name means “imitator”, in reference to it’s resemblance to pyromorphite.

Pb₅(AsO₄)₃Cl;  Hardness 3½ - 4;  Hexagonal

Calcite forms in many different geologic environments.  Usually colorless or white it can occur in many tints due to the inclusion of minor constituents during formation.  It has possibly more habits of occurrence than any other mineral. 

CaCO₃  Hardness 3;  trigonal

Goethite is the yellow- or reddish-brown alpha polymorph of iron(III) oxide-hydroxide, typically occurring in low-temperature environments.  Goethite has been well known since ancient times for its use as the pigment brown ochre. The mineral was named after the Johann Wolfgang von Goethe

α-Fe³⁺O(OH);  Hardness 5 - 5½;  Orthorhombic

Gypsum commonly forms in several environments, ranging from sedimentary evaporite deposits to hydrothermal vein deposits.  It can occur in massive granular form (alabaster), translucent white crystals (selenite is one variety), and as desert “roses.” It has extensive practical uses, such as fertilizer (for sulfur) and as building material (plaster of Paris, dry wall).  Giant crystals of gypsum occur in Mexico’s Cave of Crystals and Cave of Swords.

CaSO₄ · 2H₂O;  Hardness 2;  Monoclinic

Mimetite promotes independence of thought and action, such that the desire to imitate other’s mannerisms, life style or demeanor is decreased.  When yellow it also supports third chakra functions such as mental clarity in communication.

Calcite is used for energy cleansing and amplification and is excellent for support in learning new things and progressing in a healing practice. The Iceland Spar variety is exceptionally well suited for awareness in communication, increasing clarity and reminding us that words can have two meanings.

Goethite supports finding joy in the journey of life, combining pragmatism with imagination, and energizing the pursuit of discovery.  It supports connection with Earth so can help with dowsing and the use of divining rods.

 Gypsum supports personal growth and transformation.  It has been used in the center position of medicine wheels to synthesize the six directions and promote heart-centered thinking and action.
