Overview
This is a raw, fibrous specimen of satin spar, a crystalline variety of the mineral gypsum. Often commercially and popularly referred to as 'selenite', it is celebrated for its pearly, silky luster and the way it channels light along its natural fibrous channels.
Story
Formed in ancient evaporating seabeds millions of years ago, this mineral carries the literal memory of prehistoric waters. Its name derives from Selene, the Greek goddess of the moon, due to its ethereal, pale glow. Today, it is beloved globally by mineral collectors and wellness practitioners alike.
Maker / Origin
Likely commonly sourced from morocco, mexico, or the usa.
Condition & Value
The specimen shows typical fibrous shedding and minor fracturing along the edges, which is completely normal for this extremely soft mineral (Mohs hardness of 2). Because it is highly water-soluble, it must be kept dry to prevent degradation. Satin spar is an incredibly abundant mineral globally.
