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

The Natural Sapphire Company presents a matched pair of Ceylon blue sapphires, each weighing 0.68 carats. Both stones are round in outline and have been faceted to a mixed brilliant cut to balance sparkle and depth. The individual stones measure 5.05 x 5.06 x 3.15 millimeters and 5.04 x 5.05 x 3.09 millimeters respectively, dimensions that reflect a meticulous faceting process that preserves weight while maximizing optical performance. Clarity is assessed as very very slightly included at eye level, which translates to exceptional transparency and minimal impact on light transmission. Color intensity is described as medium intense, a level that delivers a saturated and lively blue without appearing overly dark in typical indoor and outdoor lighting. The stones have been heat treated, a standard and stable enhancement commonly applied to sapphires to refine and stabilize their color. Polish is graded excellent, and the overall finish yields clean facet junctions and a smooth, reflective surface. These objective specifications are provided to assist jewelers and designers in evaluating the pair for their intended settings.

The visual harmony of this pair derives from both their closely matched proportions and their consistent tonal qualities. In weight, the two sapphires are identical to two decimal places, and their millimeter dimensions differ by only a few hundredths, a variance that is perceptible only under magnification. This near exactitude yields a paired symmetry when set side by side, whether used as stud earrings, as companion stones in a bypass ring, or as accent stones flanking a central gem. Hue and saturation are likewise complementary. Both stones exhibit a medium intense blue that is characteristic of high quality Ceylon material. When viewed together, the stones present a uniform field of color, while subtle microvariations in tone between facets create a dynamic interplay of lighter and deeper blue flashes. This subtle interplay enhances perceived depth without disrupting overall color balance. The consistency in hue reduces the need for color adjustments in mounting and ensures that light reflected from one stone will visually integrate with light reflected from the other, producing a cohesive appearance from multiple viewing angles.

Optical performance and durability combine to make this pair particularly well suited to fine jewelry applications. The mixed brilliant cut places smaller, precise facets on the pavilion and crown to generate scintillation and return, while preserving a pleasing table and crown profile that communicates classic round geometry. The very very slightly included clarity grade allows for excellent light passage and lively facet contrast, and the excellent polish contributes to clean reflection and minimal light leakage. Heat treatment is disclosed as a stable enhancement, and originates from Ceylon, Sri Lanka, a source noted for producing sapphires with lively, medium intense blues. In practical terms, these stones will sit comfortably in a variety of design contexts, from minimalist four prong studs that emphasize color, to more complex custom settings that rely on paired symmetry for balanced aesthetics. For professionals considering allocation for a matched pair project, the combination of matched carat weight, near identical millimeter measurements, consistent color intensity, and superior finish make these sapphires a reliable choice.
