Agate

Agates come in a remarkable array of colors and patterns. You may have seen it cut into slices for wind chimes or mobiles. Agate is a common rock formation, consisting of chalcedony and quartz as its primary components.

The ornamental use of agate dates back to Ancient Greece in assorted jewelry and in the seal stones of Greek warriors. Agate has been linked to positive thinking, clarity of ideas and concentration. 

The characteristic band patterns—which begin at the center of the rock and move outwards like the rings on a tree—are visually dynamic.

Aventurine

The most common color of aventurine is green, but it may also be orange, brown, yellow, blue, or grey. Aventurine is a form of quartz.

According to legend, this kind of glass was made accidentally at Murano by a workman, who let some copper filings fall into the molten “metal,” resulting in a product called avventurino. From the Murano glass the name passed to the mineral, which displayed a similar appearance.

Magnesite

Magnesite is a gemstone that, when cut and polished into beads, features a dark thread of veins across its surface, giving it texture and interest. It is often dyed blue to act as a less-expensive alternative to turquoise, which it resembles.

In spiritual circles, magnesite’s white color leads to its association with peace, relaxation, and the strenghtening of bones and teeth.

Magnesite is a carbonate mineral, which means it captures CO2 when it forms. Scientists are experimenting with methods of artificially creating magnesite to capture CO2 in our atmosphere in an attempt to reduce the effects of global warming.

Mother of Pearl

Mother of pearl is the name given to the nacre that coats a pearl. It’s a mix of minerals secreted by oysters and other mollusks. Pearls are formed when this nacre is layered around a foreign particle, either naturally occurring or introduced (as in the case of cultured pearls). The coating of mother of pearl inside a mollusk’s shell can be used to create jewelry. It’s an abundant substance, so it’s much less expensive than actual pearls, while providing a luxurious shimmer that is reminiscent of the sea.

Mother of pearl is associated with the Moon and is believed to have a calming effect. It is a protecting, healing and soothing stone.

Pearl

Who doesn’t love pearls? With their natural luster and rarity, they have enchanted gem lovers for millenia. Natural, or “wild” pearls are extremely rare. Nowadays, most pearls in the trade are cultured in pearl farms. They are created by the same natural process as wild pearls, and retain the same beauty, though the quality and color vary depending on any number of factors.

Pearls are associated with simplicity and sophistication. In metaphysical thinking, they are the ultimate symbol for wisdom and are valued for their calming effect, as well as the bringing of integrity, loyalty, purity and protection. Classically beautifully, they can also bring a touch of whimsy when dyed in fanciful colors.

Ancient records document the mining of peridot as early as 1500 BC. It is believed to have been much beloved by the Egyptians, who jeaously guarded the locations of their mines.

Turquoise

One of the most beloved gemstones, turquoise has been prized as a for its use in jewelry and other ornamentations for thousands of years. Its unique hue makes it immensely desirable, and has led to an influx of synthetic and imitation stones. Genuine turquoise will not scratch easily, will not react with acids and has a waxy luster. All but the highest grade of turquoise must be stabilized with epoxy in order to be shaped into jewelry.

Turquoise has been associated with luck, peace and protection. It is a traditional birthstone for the month of December.

Turquoise was among the first gems to be mined. It has been in use since at least 3000 BCE, when it was beloved by the Egyptians. Deposits in California and New Mexico were mined by pre-Columbian Native Americans.
