0.66 Ct. Purple Spinel from Ceylon (Sri Lanka)

This is a beautiful transparent 0.66 carat emerald cut purple spinel measuring 6.45 x 4.01 x 2.64 mm, the stone features a classical emerald cut characterized by broad step facets, a large open table, and truncated corners that create linear flash and a refined window to the gem having a saturated body color, the clarity grade is very slightly included as evaluated at eye level which means minor platelet or pinpoint inclusions that do not detract from the gem having overall transparency or manageability for fine jewelry, the polish is excellent and facet junctions are crisp, producing clean mirror surfaces and precise facet alignment that enhance light return and create controlled flashes rather than the high scintillation seen in brilliant cuts, this spinel is untreated with no enhancement, the origin is Ceylon Sri Lanka which is known for producing intensely colored spinels, the material is singly refractive with a refractive index approximately 1.718 to 1.736, this combination of excellent polish, precise step faceting, and stable natural color makes the gem ideal for a classic solitaire or an elegant three stone ring, the dimensions and shallow pavilion also suit a low profile engagement setting or a refined pendant where the clean geometry of the emerald cut can be appreciated.

Under bright natural daylight the intense purple body color appears even and saturated, the broad table offers a calm velvety window that reveals depth of color while the step facets throw linear flashes that trace the edges of the facets as you move the piece, under cool white LED or fluorescent lighting the tone leans slightly towards cooler blue violet notes and the crisp facet planes produce more distinct whitish flashes from facet reflections, under warm incandescent and halogen lighting the purple takes on warmer redder undertones which deepen the perceived saturation and give a richer more opulent appearance, in dimmer candlelit conditions the larger facets act as planes of color that glow with a concentrated purple core while small flashes outline the facet architecture, because spinel lacks strong pleochroism the color remains consistent as the stone is rotated, the overall optical performance is therefore predictable and elegant, The Natural Gemstone Company offers this gem as a ready to set center stone for collectors and designers who require natural untreated material with precise cutting and enduring visual appeal.
