Analcime. The mineral is a hydrous sodium aluminosilicate. Normally Analcime crystals from this location are white. The unusual color of this specimen is a result of iron impurities. South Quarry. North Table Mountain. Golden, Jefferson Co., Colo.
A polished specimen of Carnelian photographed up close in direct sunlight. Crystalline layers can be seen surrounded by translucence. A form of chalcedony colored by impurities of iron oxide.
The field of view is about 2cm wide, making this about a 1:1 magnification macro using the camera's Micro Four Thirds sensor.
The last three images were taken under UV light as a little experiment. It better revealed small particles which I first thought was dust, but they are clearly embedded throughout the stone.
Sodalite is a tectosilicate mineral with royal blue varieties widely used as an ornamental gemstone. Although massive sodalite samples are opaque, crystals are usually transparent to translucent. Sodalite is a member of the sodalite group with hauyne, nosean, lazurite and tugtupite.
The people of the Caral culture traded for sodalite from the Collao altiplano. First discovered by Europeans in 1811 in the Ilimaussaq intrusive complex in Greenland, sodalite did not become widely important as an ornamental stone until 1891 when vast deposits of fine material were discovered in Ontario, Canada.

Analcime on Chabazite in a vug in shoshonite. Analcime, one of the felspathoid group, is a hydrated sodium aluminum silicate. Chabazite, one the zeolite group, is a hydrated calcium aluminum silicate. Southeast Quarry. North Table Mountain. Golden, Jefferson Co., Colo.
Phillipsite-(Ca) detail. The mineral, an uncommon member of the zeolite group, is hydrous potassium calcium sodium aluminum silicate. It occurs here in matrix of Lumbergite, a local volcanic rock characterized by the absence of feldspar. Limberg Quarries. Kaiserstuhl Volcanic Complex. Sasbach am Kaiserstuhl, Emmendingen, Baden-Württemberg, Germany.
