There are 2 Andesine-Labradorite(s) available at

This new kind of sunset colored andesine-labradorite began to appear on the market in the last few years. The specific origin remains something of a mystery and the people that know have been disinclined to share their information so far. Claims have been made that the material is from China, Mongolia, Tibet, or the Congo but nothing has been proven.

Plagioclase (Na-Ca feldspar: albite, oligoclase, andesine, labradorite,bytownite, anorthite) are part of an isomorphous series. Chemically, this material falls between labradorite and andesine in this series. Under magnification, the red platelets that are common in Oregon and Tanzania sunstone are apparent so the term sunstone is probably also appropriate in this case.
