Sunstone: The Feldspar Gemstone Sunstone Information And ...

Sunstone is an interesting feldspar gemstone with a glittery appearance and usually an orange or reddish color, hence its name. The glitter effect is caused by inclusions of the mineral Hematite, or sometimes also Goethite or Pyrite (and in one rare instance, Copper).The term used to describe the glittery effect exhibited on Sunstone is aventurescence.

Plagioclase: The Mineral Plagioclase Information And Pictures

Plagioclase: The Mineral Plagioclase Information And Pictures

The Plagioclase series is a group of related feldspar minerals that essentially have the same formula but vary in their percentage of sodium and calcium. Albite and Anorthite are the end members of the series, with the intermediary minerals Oligoclase, Andesine, Labradorite, and Bytownite. The acclaimed Dana's System of Mineralogy lists the intermediary members as individual minerals, whereas ...

Miscellaneous Properties | Mineralogy4kids

Plagioclase feldspar: The mineral plagioclase feldspar commonly shows very small, parallel lines on some of the cleavage planes. These are called striations. In some cases, these striations are the only way to distinguish plagioclase feldspar from orthoclase feldspar. Graphite: Has a greasy feel. After feeling it, check your fingers.
