Feldspar Value, Price, and Jewelry Information .

Feldspars are the most common minerals at the Earth's surface. In fact, if the entire composition of the Earth's crust were regarded as a single mineral, it would calculate out almost exactly as a feldspar. Highest values go to color and transparency in sunstone. For labradorite, size and strength of phenomena are the primary factors.

Albite Factsheet & Albite Feldspar Information

ALBITE FELDSPAR BACKGROUND INFORMATION. Albite (NaAlSi 3 O 8) is the pure Na (sodium) feldspar.In the earth's crust, feldspars are more abundant than all other minerals combined. The majority of the common feldspars fall into two groups, the alkali feldspars (KAlSi 3 O 8 through NaAlSi 3 O 8 series), and the plagioclase feldspars (NaAlSi 3 O 8 through CaAl 2 Si 2 O 8 series).

Alkali feldspars tend to display simple Carlsbad twinning, though Carlsbad twinning can be found in all feldspars (Rothwell, 1989, p.74). Grid (cross-hatched polysynthetic) twinning in two directions is a diagnostic characteristic of microcline, and lamellar (multiple) twinning occurs mainly in plagioclase (Rothwell, 1989, p.74).
