Generators are six-sided, stand on their own and are beautiful additions to any altar, crystal grid, or crystal workspace. They're thought to magnify, generate and focus energy.
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.

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.

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.

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.
