No gemstone is more creatively striped by nature than agate. This distinct and dramatically banded variety of chalcedony is composed of quartz layers. This composition varies greatly and can be of many colors. The other chalcedony family, jasper, has less-regular patterns and is less defined than the agates. Another difference between the two is that agates tend to be translucent (or at least contain translucent bands), while jaspers are generally opaque. This distinction stems from agate being composed of microscopic "fibers" of crystalline quartz while jasper is made of microscopic "grains" of crystalline quartz. Each individual agate forms by filling a cavity in a host rock. As a result, agate is often found as a round nodule with concentric bands like the rings of a tree trunk.

 

Agate is said to be named for the place it first was found — along the River Achates (now called the River Drillo) in Sicily. In ancient times, agate was highly valued as a talisman or amulet. It was said to quench thirst and protect from fever. Persian magicians used agate to divert storms. Some believed that agate would render the wearer invisible, and due to its strength and durability, it is used for making ornaments or for astrological purposes. Agate is a cooling stone and is said to cure insomnia, protect against danger, promote strength and healing, and ensure a healthy life. The major sources of agate are Australia, Canada, Mexico and the U.S.A. The gemstones of Minnesota (Lake Superior agate) and South Dakota (Fairburn agate) are agates. The gemstone of Maryland (Patuxent River Stone) is also debatably an agate, but may actually be quartzite.


Amethyst Sage Agate: (sometimes called Sage Amethyst) is a dendritic agate with a base of lilac purple, cream, white, tan or dusty sage green, with dark dendrites (branching patterns like tree branches or river deltas) and black manganese veining. Some beads are translucent like chalcedony, others are opaque, and others have portions of both. Shop Amethyst Sage Agate Beads

 

Azure Agate: Our azure agate beads are darker blue than many azure agate beads on the market. They are a vivid mix of indigo, cobalt blue, white, black, translucent gray and occasionally some red-browns. Some of the beads have dark blue or black spots like evil eye beads. Like other Fired Agate, the rich blues in these semi-precious beads are achieved via a combination of heat and dyes. The color goes great with new blue jeans, and is an economical alternative to lapis lazuli. The shades of blues found in strands of azure agate can be used for either the throat chakra or brow chakra (or, for classic WOW players, completing a quest in the Arathi Highlands).

Dyed Crazy Lace Agate has the same dramatic patterns, with the increased intensity of bright pinks, vivid turquoise blues, unusual purples, and malachite-like greens.

Druzy Agate is delicate, and is best suited for applications like pendants, earrings and pins that will not receive a lot of wear. When used in bracelets, remind your customers to treat the bracelet with care. To clean, use warm, soapy water and a soft brush. Drusy quartz rates 7 on Moh's Scale of Hardness; to avoid scratching your other jewelry, gently wrap druzy in fabric when storing it.
The stunning visual appeal of druzy beads and pendants make them a great option for jewelry focals. Sometimes spelled druse or drusy, druzy is a layer of fine crystals that forms on the surface of rock fractures and cavities (most commonly quartz) over millions of years. Druzy most commonly forms as clear quartz crystals, but can also be composed of amethyst, citrine, or other colors of quartz, and may form as crystals in the cracks and crevices in a wide variety of agates. Druzy can be enhanced to change its color, including by electroplating or vacuum coating (processes that bond a thin layer of metal to the surface of the crystal). Druzy may also be enhanced to change its color, including by electroplating or vacuum coating (processes that bond a thin layer of metal to the surface of the crystal). Shop Druzy Agate Beads

 

Our "Dzi" Agate beads are genuine agate beads that have been heat treated, dyed, sanded, laser etched, and faceted to mimic ancient Dzi stones found in India, Tibet, and other Asian countries between 1000 and 2000 BC.

Fired Agate beads (sometimes known as crackled agate beads) have a crazed or crackled surface that is created by applying heat. Heat-treating agate with various colorants is also a common method of enhancing the color of agate, so sometimes the name Fired agate refers to brilliantly multi-hued color-enhanced agate beads.
Fired Agate beads do not offer the "fire" (or flash) seen in precious fire agate or opal, and fired agate is not related in any way to true fire agate from Mexico. Nevertheless, the crackled or vividly colored appearance of these agate beads adds an attractive extra element to handmade jewelry! Shop Fired Agate Beads

Thunder Agate beads (not always available) boast similar properties to Lake Superior agate (the official gemstone of the state of Minnesota). Similarities include rich coloring with tones of tan, gray and brown often highlighted by accents of yellow, orange and red.
