Moss Amethyst

Meaning and Properties

Moss Amethyst History


Moss amethyst, also known as goethite in amethyst, was originally incorrectly labeled as cacoxenite amethyst. Upon later discovery, it was found the inclusion was goethite, and that cacoxenite amethyst may not actually exist. Since it has been historically labeled as cacoxenite, many people still use this incorrect name.


Amethyst (pronounced AM-eh-thihst) is one of the most common--and popular--gemstone materials. This variety of quartz ranges in color from deep purple to pale lavender depending on the presence of manganese and iron.


Goethite (pronounced goh-thahyt) is sometimes called the "fairy paint box" when used by artists or in cosmetics because it can unexpectedly appear to sparkle within another mineral. It is also a source for ochre pigment. Goethite has been a pigment used since prehistoric times and was found in early cave paintings in France at the Lascaux.


The two minerals together create the intriguing moss amethyst. Moss amethyst is translucent to transparent purple with rutile-like inclusions instead of a fully saturated purple. Some may include patches of a solid purple, but overall, they maintain a clear stone with a purple hue with needle inclusions throughout.

Moss Amethyst Metaphysical Properties


Amethyst has been believed by many to prevent drunkenness and have the power to quell a range of other physical appetites and indulgences. This sobering effect is also believed to clarify mental acuity, improving the decision-making ability of those who wear it. This made it a popular choice for giving to young men--helping them avoid temptation and keeping them clear-minded when using weapons.


Amethyst is often used during meditation to provide an overall sense of spiritual balance. Some naturopaths will use amethyst to help treat insomnia and sugar imbalances, and to relieve headaches.


Goethite is thought to encourage creation for pleasure and expression without fear of public scrutiny. It is a healing crystal for the root, sacral, and solar plexus chakras. For physical benefits, goethite is sometimes used to assist with digestion, circulation, anemia, oxygenation of blood, bone marrow, absent or scant menstruation and convulsions, and connective passages, such as ears, nose, throat, and esophagus.


The combination of goethite and amethyst together as moss amethyst creates what many believe a powerful healing crystal. It has the potential to transmute lower to higher frequencies and transform energy.


Moss Amethyst Geological Properties


Quartz can grow in many different environments. In these environments, there are often other minerals growing as well, and these can get trapped inside a growing crystal. While the crystal grows, the minerals continue to grow as well. A soft mineral will be protected from chemicals and other harsh environmental conditions by the crystal. This is how moss amethyst forms. As the quartz variation of amethyst forms, small goethite minerals become trapped within the crystal. The soft goethite mineral of a hardness of 5 (Mohs) now becomes protected by the quartz crystal.


Moss amethyst is composed of light transparent to translucent purple, speckled with entrapped iron minerals of goethite. The purple color of the amethyst is caused because of magnesium and iron, while the goethite is mainly made of iron. Goethite’s color is brownish-black, yellow-brown, to reddish brown. However, it may also be iridescent with a rainbow of darker toned colors. Goethite is an iron oxyhydroxide containing ferric acid. It is the main component of rust and bog iron ore. In amethyst, goethite often forms colored needles throughout the crystal. No two moss amethyst crystals will be the same, making them incredibly unique. Goethite in amethyst, or moss amethyst, is typically a variation found in Brazil.

Proper Care of Moss Amethyst


Moss amethyst is durable enough (7 on the Mohs scale) to be cleaned using ultrasonic cleaners or steamers. Avoid the use of bleach and other harsh household cleaners and be sure to rinse your stones well to ensure all soapy residues are removed.

Designing with Moss Amethyst


The soft hue of moss amethyst is best paired as a focal or pendant with silver chain or cord. The translucent opacity and hue of the gemstone adds intricate color depth to bring life to jewelry without overwhelming designs. However, its unique inclusion adds a touch of individuality to bring attention to its intriguing look. Its durability allows for versatility in jewelry- or accessory-making for men and women. It can be used for traditional jewelry, such as bracelets, necklaces, and earrings, or more complex creative pieces.
