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.

Unit price perImpact Melt Rock | 9.8 grams | Dhala Impact Structure | 3rd Oldest Impact | India
$12.00 CAD
Unit price perThis is a must have 9.8 gram Impact Melt Rock from the Dhala Impact Structure, India. It measures 40x26x5 mm. Although not a meteorite, impactites are directly linked to them and their impacts and are probably going to be one of the rarest collection items you'll ever own. Impactite is a slag-like glassy object found on the surface of the earth, formed from rock melted by the impact of a meteorite.
The term impactite encompasses shock-metamorphosed target rocks, melts or suevites and mixtures of the two, as well as sedimentary rocks with significant impact-derived components and shocked mineral grains, tektites, anomalous geochemical signatures, etc.
This beautiful Impact melt rock comes from the 11 km-diameter highly eroded Dhala impact structure in India. The Dhala structure has an estimated age of about 2Ga (2,000 Ma), making it the third oldest terrestrial impact structure.
This gorgeous slice displays very well. Would be a beautiful addition to any new or existing collection. Comes with a Canagem Collection specimen card.

The term impactite encompasses shock-metamorphosed target rocks, melts or suevites and mixtures of the two, as well as sedimentary rocks with significant impact-derived components and shocked mineral grains, tektites, anomalous geochemical signatures, etc. This impactite was formed 14.5 million years ago in Malmian or Jurassic limestone when a meteorite crashed into the earth making a ~10 miles wide crater named the Ries crater in Germany.
This gorgeous part end cut displays very well, it is amazingly light considering its mass of 36x31x19 mm. Would be a beautiful addition to any new or existing collection. Comes with a Canagem Collection specimen card.

This is a specimen of Star Mica or Muscovite and Quartz cluster. These clusters show crystals that grow in sheets or book formations. It is silvery gold with good transparency when held up to the light. The name Muscovite comes from the term Muscovy Glass which was a name for the thick sheets of Mica used as a substitute for glass Russia. The name Mica is derived from the Greek word that means to split.
On this nice specimen, the matrix faces are covered with beautiful golden yellow point stars of muscovite mica, a typical shape for this rare mica formation. The stars are the result of twinning; the points show a bit of wear but this does not detract from the beauty of such a piece.
