feldspar mineral minerals

Feldspar - Wikipedia

The feldspar group of minerals consists of tectosilicates, silicate minerals in which silicon ions are linked by shared oxygen ions to form a three-dimensional network. Compositions of major elements in common feldspars can be expressed in terms of three endmembers: • potassium feldspar (K-spar) endmember KAlSi3O8 • albite endmember NaAlSi3O8

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.Specimens sold to collectors are usually polished or sliced by dealers to fully bring out this effect.
