3.50 Ct. Blue Sapphire from Ceylon (Sri Lanka)

This transparent Ceylon blue sapphire weighs 3.50 carats, and is presented in an elegant oval outline measuring 10.89 x 8.20 x 5.00 mm, which yields an approximate depth ratio of fifty two percent when calculated against the mean of the length and width, a proportion that promotes strong light return without sacrificing color saturation. The stone is faceted in a mixed brilliant style, with a full brilliant crown above a precisely calibrated pavilion that incorporates modified facet relationships to balance spectral return and color body. The mixed brilliant approach in this case places emphasis on smaller, well defined crown facets to generate scintillation, while the pavilion facets are arranged to control light leakage and to enhance the internal interplay of blue and violet pleochroic directions. The cutter has preserved clean facet junctions and symmetry, and the polish is graded excellent, providing a smooth reflective interface that maximizes brilliance and reduces optical scattering from surface imperfections. Clarity is described as very slightly included when viewed at eye level, a clarity that allows for full transparency and strong fire, while retaining natural characteristics that affirm the stone is a natural corundum rather than a synthetic or heavily treated material.

Color is the defining characteristic of this sapphire, evaluated as intense in overall color intensity, with a primary pure blue hue and subtle violet overtones that are typical of fine Sri Lankan material. The combination of transparent crystal structure and intense saturation in this specimen produces high chroma without the heaviness sometimes associated with stones that are overly dark, so the gem reads as vivid blue under standard daylight and retains lively tone under incandescent lighting. Compared to historical and museum quality sapphires, this stone occupies a distinct niche. It differs from the velvety blue of classic Kashmir sapphires in that it shows greater crystalline transparency and facet brilliance rather than the softened diffusion produced by silk inclusions in Kashmir material. It contrasts with famous star sapphires like the Star of India, which are valued for asterism and are often cut as cabochons, because this mixed brilliant faceted oval prioritizes scintillation and color flash over asterism. When placed in context with large Ceylon examples such as the Logan Sapphire, which is celebrated for its broad color field in a museum scale, this 3.50 carat oval offers the advantage of well controlled faceting that delivers concentrated brilliance and adaptability to fine jewelry settings. The result is a stone that offers both the desirable Ceylon blue character that has been prized historically and the precision of modern lapidary technique.

Origin and enhancement are part of the stone profile, the sapphire is heat treated, a stable and widely accepted enhancement for sapphires, applied to relieve silk related haze and to intensify the blue without altering the crystal lattice in a way that would compromise long term stability. The provenance from Ceylon Sri Lanka is consistent with the observed color and inclusion type, and is a key element of the stone value proposition given the long historical association of Sri Lankan mines with high quality blue corundum. From a setting and design perspective, the cutter has oriented the pavilion and crown to optimize the dominant pleochroic axis, a consideration that will allow a trained jeweler to orient the stone in a mounting so that the viewer perceives the most saturated blue face up. For collectors and connoisseurs who assess gems by proportions optics and provenance, this sapphire represents a rare combination of intense color, high transparency, precise mixed brilliant cutting, and an excellent polish in a 3.50 carat size, a combination that is less common than it appears when compared to larger museum stones that may sacrifice personal wearable qualities for scale. The Natural Sapphire Company presents this gem as an example of contemporary lapidary mastery applied to classical Ceylon material, offering performance in light, color, and clarity that stands in elegant conversation with the great historical sapphires while maintaining its own distinct value for both jewelry use and specialist collections.
