Natural Black 6 Ray Star Sapphire 1.41ct 6mm Round Cabochon Untreated

A natural black star sapphire round cabochon with a bright, prominently displayed 6-ray star that blazes from the center of the high dome. The stone glows with warm golden-bronze tones under incandescent light, with the star arms radiating cleanly outward from a bright pinpoint center — a hallmark of a well-oriented cabochon cut. Despite its compact 6mm footprint, the star is large and unmistakable.

Completely untreated and sourced from Thailand, this round cabochon represents the classic black star sapphire form. The 6mm round size fits standard cabochon settings and is equally suited to solitaire rings, stud earrings, or small pendant bezels where the star effect takes center stage.
