Selenite is a type of gypsum, a hydrous calcium sulphate, usually transparent and colorless, and is soft with a hardness of 2.

These clear, layered Selenite pieces are from Utah.

The name selenite comes from the Greek words "selene" meaning "moon," and "lithos" meaning "stone," because it was believed to wax and wane with the moon.

Metaphysically speaking, selenite is known to help with awareness, understanding the deeper meaning in any given situation, strengthening decisions, and encourages good business practices. It is said to align the spine, benefit the skeleton, neutralize mercury poisoning and decrease epilepsy and seizures.

These Selenite logs are amazing pieces from Africa.  
They range from 3"-8" in diameter and 10"-22" in length.  

To get an idea, the following is a sample of some approximate weights.
A 6"x10" log = 13 pounds, a 4"x12" log = 9 pounds and, a 6"x20" log = 33 pounds.  
Remember, rough rock is sold by the pound.

What is Slag Glass?  Partly vitrified non-metal residue and waste material left behind after the smelting of a metal ore or in glassmaking and has a hardness of 5.5 to 6.

Vitrification is a process of converting a material into a glass-like amorphous solid that is free from any crystalline structure, either by the quick removal or addition of heat, or by mixing with an additive.  When the starting material is solid, vitrification usually involves heating the substances to very high temperatures.  Many ceramics are produced in such a manner.  Vitrification can occur naturally when lightning strikes sand creating hollow, branches of glass, called fulgurite.

Sodalite is a sodium aluminum silicate chloride, in the feldspathoid group, and has a hardness of 5.5 to 6.  Distinguished by its rich royal blue color, sodalite can also be yellow, green, or violet and is often mottled with white veins or patches.

These sodalite specimens are a gorgeous royal blue
to a very dark blue with white veining, comes from
Brazil and is great rough for cabbing.

Sodalite gets its name for its high sodium content.  It is similar to lazurite and lapis lazuli however, unlike sodalite, lapis has pyrite inclusions.

Metaphysically speaking, sodalite is known to increase self-esteem, creativity, communication, to eliminate confusion, bring peace of mind and to assist in spiritual growth.  It can be placed on or near electronic equipment to clear electromagnetic toxins.  It is said to improve calcium deficiencies, strengthen the lymph system, relieve insomnia and damage from radiation.

Tourmaline, a complex silicate mineral, has a wide variety of colors. Usually, iron-rich tourmalines are black to bluish-black (schorl) to deep brown (dravite), while magnesium-rich varieties are brown to yellow, and lithium-rich tourmalines are practically any color: blue, green, red, yellow, pink etc., in hexagonal crystal structures, and has a hardness of 7 to 7.5.

These Tourmaline specimens occasionally show
botroydal formations (bubble-like) and come from Brazil.

The name Tourmaline has two derivatives, both from the Sinhalese word "turamali," meaning "stone attracting ash" referring to its pyroelectric properties (when the crystal is heated it gives a positive charge at one end of the crystal and a negative charge at the other) , or according to other sources it means "mixed gemstones".  Tourmaline has many technological uses due to its piezoelectric properties, (an electrical charge can be created by simply applying pressure to the crystal on the vertical axis), which is useful in measuring equipment and other scientific applications.

 Metaphysically speaking, black tourmaline, is known to be a very protective stone, purifying, deflecting and transforming negative energy for an individual or environment, and is excellent for grounding excess energy.  It is also used to deflect radiation from tv's and computer monitors. It is said to strengthen the immune system, help with heart disease, arthritis, and gout.

 Turritella agate is a type of fossil, petrified snails, where all the organic matter was replaced with quartz, so has a hardness of 7.

This Turritella agate exhibits an amazing amount of fossils,
comes from Wyoming and is great rough for cabbing.

Turritella agates are actually fossilized Goniobasis gastropods.  They lived about 50 million years ago.  The shell of this snail had a small, tapering spire with many spirals and grew up to 1 1/2" long. The shell material has been completely replaced by agate while retaining dramatic spiral patterns.

Metaphysically speaking, turitella agate is said to dispel a superiority complex, help with transitions and give insight in knowing that all is well, regardless of the outcome.  It also helps with calming, reduces fatigue and is helps stomach issues.
