1.30 Ct. Blue Sapphire from Ceylon (Sri Lanka)

This transparent 1.30 carat blue sapphire, presented by The Natural Sapphire Company, is cut in a classic emerald shape with precise faceted step cutting, dimensions 6.99 x 4.95 x 3.74 mm, and an overall depth of 62.7 percent. The stone displays a vivid color intensity that is characteristic of fine Ceylon origin, and the heat treated enhancement has been executed to stabilize and intensify the inherent cornflower to royal blue tones without compromising transparency. The emerald cut emphasizes broad, open facets, a dominant table, and parallel step facets on both crown and pavilion, producing a disciplined hall of mirrors effect rather than a scattering brilliance. The excellent polish on facet junctions and the consistent symmetry of the step facets allow clean light return and a controlled play of tone, making the color read saturated and even across the table when viewed face up.

Clarity is graded eye clean, evaluated at eye level, yet the stone retains microscopic internal features that are integral to its natural character and provenance. Under magnification one can observe delicate silk like rutile networks and minute healed fissures, together with tiny negative crystals, which are not visible without optical aid but which serve as unique internal fingerprints. These inclusions act as identification markers that gemmologists and experienced cutters use to match a stone to origin, and they contribute subtly to the velvet sheen that deepens the blue in certain viewing angles. Because these features are microscopic, they do not detract from the gem quality or visual purity, but they do confirm the natural history of the sapphire and the authenticity of its Ceylon origin.

From a craftsmanship perspective the cutter optimized pavilion depth and step facet geometry to balance color saturation with face up brightness, a deliberate technique for emerald cut sapphires where color is the primary attribute. The result is a gem with a calm, architectural appearance that suits precision settings, including low bezel seats and open prong mounts that allow light to enter the pavilion, enhancing perceived saturation. For collectors and connoisseurs who value both technical execution and natural character, this 1.30 carat emerald cut Ceylon sapphire offers a refined synthesis of cut, color, clarity, and documented origin, supported by The Natural Sapphire Company quality standards.
