0.97 Ct. Purplish Blue Spinel from Ceylon (Sri Lanka)

This listing presents a transparent purplish blue spinel weighing 0.97 carat, with dimensions 6.24 x 4.89 x 3.97 mm, cut in a cushion shape and finished as a faceted stone. The cutting style is a mixed brilliant cut, combining the scintillating facet architecture of a brilliant pavilion with a structured crown facet pattern, delivering a measured interplay of brilliance and color. Clarity is graded very slightly included, evaluated at eye level, which preserves visual transparency while contributing subtle internal character under magnification. Color intensity is classified as intense, and the stone exhibits an excellent polish. The spinel is natural, untreated, and of Ceylon, Sri Lanka origin, offered by The Natural Gemstone Company.

The mixed brilliant cutting approach optimizes the stone for both light return and color saturation, enhancing the inherent optical properties of this purplish blue spinel. The cushion outline, with its gently rounded corners and well proportioned table, allows broader crown facets to act as windows that admit light into the body of the stone, while the brilliant style pavilion facets create numerous internal reflections that redirect light back through the crown. This coordinated facet geometry enhances apparent brightness and yields lively scintillation as the piece moves, and it concentrates spectral flashes of color by breaking light into discrete flashes without overpowering the base hue. Excellent polish minimizes surface scattering and ensures that light paths remain crisp, increasing contrast between bright facet faces and darker facet junctions for greater visual depth. The lack of any enhancement preserves the stone natural pleochroic tendencies, so the cut is intentionally balanced to retain intense color when viewed face up, while allowing controlled light penetration to reveal internal features consistent with the very slightly included clarity grade. The result is a carefully cut cushion spinel that exemplifies natural color, precise craftsmanship, and predictable optical performance, an offering representative of the standards maintained by The Natural Gemstone Company.
