A worry stone is the perfect aid for anxiety and nervousness. Hold it in your hand, fiddle with it, stim with it, and let it help release your fears and worries. Our worry stones vary in size from approximately 3-4 cm in length.

Moss and tree agates are formed from chalcedony, though this stone lacks the characteristic banding that would make it a true agate. The green inclusions are iron or manganese, and often look like ferns or other kinds of vegetation. 

According to The Crystal Bible by Judy Hall, moss agate is "a stabilizing stone strongly connected with nature" and is refreshing and a highly optimistic stone. We have a customer that swears by putting pieces of moss agate with her potted plants, and we find the stone to be very linked to the vitality of life.

Amethyst is a variety of quartz which gets its color from irradiated iron and other minerals. It typically grows in clusters of 6-sided prisms of hues from light violet to deep purple. They have been used in jewelry since ancient Egypt and were particularly popular for intaglio, and they were once considered as rare and valuable as emeralds and sapphires until large deposits of volcanic geodes were found in Brazil. By the modern era, though, it has been found as far and wide as South Korea, Australia, and Canada. According to the American Gem Society, it is the birthstone for February.

The Greek name, améthystos, literally means "not intoxicated," due to the Greek and Roman belief that amethyst can prevent drunkenness. For this reason, they wore amulets of amethyst and made wine cups from amethyst. To this point, the titan Rhea presents the god Dionysus with amethyst to help him keep his sanity in Dionysiaca.

Medieval Europeans, however, believed that amethyst could help with healing and helped preserve soldiers on the battlefield. It was also considered a symbol of royalty, though this may be due to its purple hue. At one time, it was practice for a lady to present it to her knight or a wife to her husband, in the shape of a heart and set in silver, to bring happiness and heavenly blessing on the couple.

According to The Book of Talismans, Amulets, and Zodiacal Gems by William Thomas and Kate Pavitt, Amethyst is connected to the sign of Pisces, and according to Tropical Gemstones by Carol Clark, Tibetans consider Amethyst sacred to the Buddha and make prayer beads from it.

Episcopal rings are usually set with amethyst, giving it the title "the Bishop's stone." Amethyst was once a common material for rosaries, believing the stone material would help calm the mind of the rosary's user. It is also the stone of St. Valentine. Amethyst also appears in Exodus 28:19 & 39:12 as one of the stones on the breastplate of a priest, where it is refered to as "‘achlâmâh" which might mean "dream stone."

Aventurine is a quartz with inclusions of mineral platelets which give it a glittery effect. The most common color is green, but it also comes in blue, brown, gray, orange, and yellow. Its name comes from the Italian "a ventura," meaning "by chance." This is a reference to the accidental discovery of aventurine glass in the 1700s.

According to The Golden Bough by Sir James George Frazer, the Lotuko, Bari, and Lokoya of South Sudan have used aventurine, quartz, and amethyst as rain stones in rain-bringing rituals.

Lapis lazuli, basically meaning "blue stone," is a deep blue metamorphic rock usually found in crystalline marble that has been extremely prized throughout history as both as a semi-precious stone used for jewelry and ground down to produce ultramarine -- the most expensive blue pigment. This pigment was reserved by some artists exclusively for depictions of the Virgin Mary. Most lapis lazuli also contains white pigment from calcite and yellow pigment from pyrite as well as blue pigment from sodalite. The characteristic intense blue of ultramarine, however, is derived from the presence of trisulfate in the stone.

Lapis lazuli has been mined in Afghanistan since the neolithic age, and lapis lazuli-containing artifacts have been found throughout the Indus Valley, Mesopotamia, Mycenae, Shahr-e Sukhteh, Sumeria, and modern day Syria as well as throughout the land once occupied by ancient Egypt.

Moonstone is a variety of feldspar with a wide variety of colourations. It's formed of orthoclase feldspar and albite feldspar which have mixed and then cooled into thin, alternating layers. These layers scatter light similar to the way ripples in water will interfere with each other, causing the phenomenon known as adularescence, which itself is described as an effect similar to moonlight on water. Sometimes, due to internal flaws, rough shape, inclusions, or pigment, the adularescence of a moonstone maybe so subtle as to simply look slightly shinier than usual.

Adularescence is not the same thing as "flash," which is the phenomenon of coloured light appearing on or within a stone. Colourless moonstone may exhibit blue flash. When it is able to exhibit multiple colours of flash (usually greens and yellows), it is called "rainbow moonstone." Rainbow moonstone is able to exhibit these colours due to inclusion of labradorite. For this reason, the stone has also been called "white labradorite."

The diffractive properties of the stone caused ancient peoples to believed moonstone to be solidified moonlight. Because of this, it has been popular in jewelry since ancient times, and it was associated with Selene and Luna as well as Hecate, from whom it gains the name "hecatolite." It has been thought to give protection to sailors.

It is thought that moonstone can activate intuition and help calm emotional turmoil.

Because of its connection to the moon, it would be a good stone for Cancers.

Quartz is a silicon crystal usually occurring in the form of druzy, 6-sided prisms, or massive crystals and it is the second-most abundant mineral on earth. It has been most commonly used for carved art and for jewelry, though their piezoelectric abilities are also highly useful. Its clear form is often referred to as "rock crystal," and ancient philosophers once thought it was a form of supercooled ice. Though this product is the rock crystal form of quartz, quartz also comes in the forms of agate, amethyst, aventurine, carnelian, chalcedony, citrine, jasper, milky quartz, onyx, prasiolite, rose quartz, rutilated quartz, smoky quartz, and tiger's eye.

Rock crystal quartz is an invaluable component of the crystal oscillator, which is invaluable to precise timekeeping devices and solid state electronics. One of the first contexts for this use was as a phonograph pickup. Additionally, due to its triboluminescent properties, quartz crystals were collected and used by the Ute people of Colorado to generate flashes of light in night ceremonies. It is thought that quartz may be the maban stone of Aboriginal Australian lore. In Ireland, it is referred to as "sun stone," possibly because of it's ability to split light into a spectrum.

Rock crystal is, in fact, the traditional material of crystal gazing balls. According to The Book of Talismans, Amulets, and Zodiacal Gems by William Thomas and Kate Pavitt, because of the Moon's rule over the sign of Cancer and powers of intuition, rock crystal/clear quartz is thus a stone well-matched with Cancer.

Tiger Eye is a kind of quartz with gold to red-brown colour, and chatoyancy (cat's-eye) that makes it very attractive when it's polished and cut to show off the 'eye'. It has a lovely silky lustre.

A good protection stone, it's best used to protect against curses and the jealous. It's also excellent for helping you focus on your goals, realize what's attainable, and lift yourself out of a heavy funk.

Black tourmaline, also known as schorl, is a crystalline boron silicate mineral compounded with iron and sometimes other elements, such as aluminum, lithium, magnesium, potassium, or sodium. It wasn't until the 18th century that it was realized that German schorl and Sri Lankan tourmaline were the same mineral. Schorl derives its name from the German village where it was originally found in abundance. The name "tourmaline," however, is derived from the Sinhalese words "turmali" and "thoramalli" for two different types of tourmaline gems. Tourmaline is currently mined in Afghanistan, Brazil, Kenya, Madagascar, Malawi, Mozambique, Namibia, Nigeria, Pakistan, Sri Lanka, and Tanzania.

Tourmaline is a six-member ring cyclosilicate having a trigonal crystal system. It occurs as long columnar and prismatic crystals that are usually triangular in cross-section, often with curved striated faces. Tourmaline is distinguished by its three-sided prisms as no other common mineral has three sides.

All tourmaline, and especially schorl, is pyroelectric, piezoelectric, and ferroelectric. Schorl displays the ability to attract and repel hot ash.
