1.44 Ct. Blue Spinel from Ceylon (Sri Lanka)

One transparent 1.44 carat oval blue spinel from Ceylon offered by The Natural Gemstone Company measures 8.32 by 6.30 by 3.55 millimeters, and is faceted with a mixed brilliant cut. The cut and excellent polish yield crisp facet junctions and strong surface reflections, producing a controlled, lively return of light that emphasizes the stone's intense blue saturation. Clarity is described as very very slightly included when evaluated at eye level, which means inclusions do not disrupt the overall sparkle or the stone's even color distribution. No enhancement has been applied, so the observed reflective behavior and color depth are entirely natural, and the mixed brilliant pavilion design is optimized to balance scintillation and broad flash across the oval plane.

When compared to other blue gemstones, this Ceylon spinel presents a distinctive reflective profile. Spinel has a refractive index around 1.718 and low dispersion approximately 0.018, which produces bright, focused reflections without excessive spectral fire, similar in this respect to corundum species such as sapphire but with subtly different character. Against blue sapphire, the spinel often appears cleaner and more evenly lit under the same cutting geometry because spinel specimens frequently show fewer silk like inclusions, allowing sharper facet reflections and more pronounced contrast between light and dark facets. Compared to blue topaz, tourmaline, or aquamarine, which have lower refractive indices and therefore softer, less brilliant reflection, this spinel offers noticeably stronger facet brilliance and crisper scintillation. The stone’s intense color intensity concentrates light absorption in the blue region while maintaining transparent windowing where light returns as deep blue flashes, making the reflective qualities appear richer and more saturated than gemstones with paler tones. The excellent polish accentuates surface brightness, and the mixed brilliant cut maximizes the interplay between brilliance and color, resulting in a balanced, sophisticated appearance well suited to settings that showcase top light return.
