Unakite

Meaning and Properties

History


Unakite is a true rock: a composite material made up of multiple other stones. This gives unakite its familiar moss-on-brick appearance and makes it a popular lapidary material. The patterns, durability and affordability of unakite have also made it a useful stone for architecture--its most prominent use is trimming on the front steps of the Smithsonian Museum of Natural History in Washington, D.C.!


Unakite was first discovered in the United States, in the Unakas mountains of western North Carolina/eastern Tennessee (hence its name). However, it can also be found on the beaches of Lake Superior, where it was originally dragged by glaciers, as well as washed down from the mountains into rivers in Virginia.

Metaphysical Properties


Unakite is said to be a stone of vision, opening the third eye and useful for scrying. It is also believed to be a stone of balance, grounding the self while bringing emotions and spirituality together.


Among crystal healing practitioners, unakite is used to support convalescence from illness. It is also believed to affect the reproductive system, healthy pregnancy and the growth of skin and hair.


Unakite is associated with two chakras: to the third eye chakra for its use in vision and scrying and to the heart chakra for its ability to balance emotions. It is not a current birthstone, but it has been historically assigned to March. It is also thought to offer patience and balance to Capricorn and Scorpio.


Geological Properties


This metamorphic rock is formed when granite is altered by hydrothermal activity. Unakite--also referred to as epidote/epidotized granite--blends green epidote, pink orthoclase feldspar and clear quartz and can contain trace amounts of other materials such as magnetite or zircon. As a rock (not a gemstone or element), unakite is found only in masses, not in crystal forms.


Unakite deposits may be found in not only the United States, but also Brazil, China, Sierra Leone and South Africa.

Proper Care of Unakite


Unakite is not a porous stone, but it can be sensitive to chemical cleaners due to its composite makeup. Avoid using ultrasonic and steam cleaning, as unakite can cleave under impact and heat can change this stone's colors. A soft cloth or brush with mild soap and warm water are ideal. Rinse off all cleaners, then pat dry with a soft cotton cloth.

Designing with Unakite


Unakite is a great stone for men's and unisex jewelry styles. It's a colorful choice that works with a range of metals and other materials due to its mix of cool and warm hues. Unakite's multiple color tones really pop when used with black onyx or white mountain "jade." The greens can be accented by mingling with dark green aventurine while the reds can be brought to the fore by stringing with red jasper.


Unakite cleaves cleanly under impact, so it is not recommended for ring, bracelet or anklet designs.
