Unit price perThis is an incredibly beautiful and flashy piece of Canadian Labradorite. Labradorite is an unusual mineral. It can display a beautiful iridescent play of colors, caused by internal fractures in the mineral that reflect light back and forth, dispersing it into different colors. This effect, known as labradorescence, gives Labradorite its appeal and fame.

Unit price perOrpiment is known for its strikingly bright yellow color, though it can also be bright orange or lustrous brown. The name Orpiment is derived from the Latin Auripigmentum, meaning gold pigment, in reference to its color and historical use as a golden-yellow pigment. Orpiment is often associated with bright red Realgar, and may form in strikingly colored and unique mineral combinations.
Orpiment is a photosensitive mineral and will eventually dull and develop a white powdery film upon prolonged exposure to light. Due to the instability of Orpiment, specimens should be stored enclosed and covered to prevent their exposure to light. Occasional exposure to look at a specimen will not cause damage; only prolonged or repeated exposure will cause deterioration.
Orpiment contains a significant amount of poisonous arsenic, and is itself somewhat toxic. Washing hands is recommended after handling Orpiment specimens, especially if powdery.
This is a quality specimen that would be a beautiful addition to any new or existing rock collection.

This is a lovely raw garnet are from Ontario, Canada. Garnet is a stunning gemstone known for its rich color, primarily deriving its vibrant hues from the presence of iron and manganese. The name "garnet" is believed to come from the Latin word "granatum," meaning pomegranate, due to its resemblance to the fruit's seeds. Historically, garnets have been used since the Bronze Age, prized not only for their beauty but also for their protective qualities.
Garnets are believed to enhance self-confidence and inspire love and passion. They are thought to ground energy and bring balance, promoting a sense of stability and security.

Pseudomorph Goethite After Marcasite | Prophecy Stone | 38 gr | Farafra Oasis, Egypt

Unit price perPseudomorph Goethite After Marcasite | Prophecy Stone | 38 gr | Farafra Oasis, Egypt
$42.00 CAD
Unit price perPseudomorphs are mineral specimens that have the external shape of one mineral but are composed of another. The pseudomorph goethite after marcasite forms when marcasite is exposed to oxidizing conditions and starts to oxidize and break down. As the marcasite breaks down, goethite replaces it in the crystal structure, preserving the shape of the original marcasite crystal. The resulting specimen appears as a marcasite crystal, but is actually composed of goethite.
The Farafra Oasis, in the White Desert, has been known for a number of years to deliver incredible pseudomorph specimens. The pseudomorphs occur within the Cretaceous Khoman Chalk, from which the White Desert derives its name.
These specimens are remarkable for their relatively sharp marcasite crystal forms in aesthetic crystal clusters. They are in excellent condition. This collector's specimen is unique, of great quality and ready for display.

Olivine Volcanic Bomb | Lava Coated Crystal | 254.5 gr | Mt Shadwell Volcano, Australia
$140.00 CAD
Unit price perOlivine Volcanic Bomb | Lava Coated Crystal | 254.5 gr | Mt Shadwell Volcano, Australia
$140.00 CAD
Unit price perAn olivine volcanic bomb is a type of volcanic rock that contains olivine crystals and has been ejected during a volcanic eruption. Olivine is a mineral that is commonly found in the Earth's mantle and is one of the first minerals to crystallize as magma cools.
Volcanic bombs are large clots of lava that are ejected from a volcano during an explosive eruption. They can vary in size, and their shapes are often streamlined due to their molten nature as they are thrown through the air. When these volcanic bombs contain olivine crystals, they are referred to as olivine volcanic bombs.
This piece has been cut to showcase the beautiful green olivine crystals. It would be a beautiful addition to any new or existing collection. Comes with a Canagem Collection specimen card.

Some are a frosted snow white ball shape which sit amongst a sharper sparkly druzy calcite. It is in excellent condition.
Calcite is found throughout the world in sedimentary, metamorphic, and igneous rocks. Some geologists consider it to be a "ubiquitous mineral" - one that is found everywhere. Calcite is the principal constituent of limestone and marble.

Iceland spar, formerly called Iceland crystal (Icelandic: silfurberg [ˈsɪlvʏrˌpɛrk], lit. 'silver-rock') and also called optical calcite, is a transparent variety of calcite, or crystallized calcium carbonate, originally brought from Iceland, and used in demonstrating the polarization of light.
The most common crystal structure of Iceland spar is rhombohedral, but other structures, such as scalenohedral or prismatic, can form depending on formation conditions. Iceland spar is primarily found in Iceland but can occur in different parts of the world with suitable geological conditions such as China.
