0.66 Ct.Tw.Total Carat Weight Blue Sapphire Pair from Ceylon (Sri Lanka)

This pair of Ceylon blue sapphires presents a study in proportion and color harmony, combining precise cutting with consistent material quality. The gems weigh 0.32 carats and 0.34 carats respectively, with diameters measured at 3.99 by 3.99 by 2.48 millimeters, and 4.03 by 4.03 by 2.62 millimeters. Both are fashioned as round mixed brilliant cuts, a faceting strategy that emphasizes scintillation on the crown while controlling color saturation through the pavilion geometry. The mixed brilliant format delivers a balance between brilliance and depth, making these stones visually compatible when set as a matched pair. The Natural Sapphire Company presents them as an example of meticulous matching, where minute differences in diameter and depth are intentionally managed to produce a cohesive visual result under varied lighting conditions.

From a cut and craftsmanship perspective, the mixed brilliant treatment applied to these sapphires optimizes light return and contrast for stones of their proportions. The crown facets have been aligned to a consistent table diameter and symmetry, yielding crisp star facets and a uniform pattern when viewed table on. The pavilion facet arrangement has been calibrated to enhance color reflection rather than maximize pure white light flash, which is ideal for sapphires that possess strong intrinsic color. The excellent polish reported on both pieces is evident in smooth facet junctions and a lack of extraneous surface luster disturbance, factors which maximize both brilliance and the apparent clarity of inclusions. The pair demonstrates careful attention to girdle thickness and overall proportionality, ensuring secure setting options without compromising optical performance.

Color and clarity are central to how these two stones complement each other in hue and presence. Both sapphires show intense color intensity, which manifests as saturated blue tones with a lively medium to deep tone balance. The origin of Ceylon, Sri Lanka, contributes a characteristic cornflower to slightly violet influenced blue, which in these examples reads as a vivid, dimensional blue when observed in standard viewing environments. Clarity is graded as very slightly included, evaluated at eye level, meaning that inclusions are minor and do not detract from transparency or light transmission in normal wear. The very slight inclusions present act to subtly influence internal light scattering, in some positions adding a gentle, lively scintillation that complements the mixed brilliant faceting. Both stones have been heat treated, a standard and stable enhancement for Ceylon sapphires, applied to refine tone and clarity while preserving natural origin characteristics.

When considered as a matched pair, the 0.32 carat and 0.34 carat sapphires demonstrate an intentional complementarity in both size and hue, conducive to high quality matched settings such as earrings, a twin pendant design, or accent stones in bespoke creations. The almost negligible difference in diameter, approximately 0.04 millimeters, ensures that when mounted side by side the stones read as a unified pair, while the slight variance in depth contributes to a natural play of light between the two, avoiding an overly mechanical symmetry that can sometimes diminish visual interest. The intense, Ceylon blue character is consistent across both stones, allowing them to reflect light in a similar color range while each stone retains a subtly distinct personality that speaks to natural origin and careful lapidary work. For clients seeking technical refinement and matched optical performance, these sapphires exemplify the standards curated by The Natural Sapphire Company, combining precise measurement, expert cutting, and origin certification into a pair that performs reliably in design and in daily wear.
