2.43 Ct. Blue Sapphire from Ceylon (Sri Lanka)

This 2.43 carat cushion shape blue sapphire measures 7.96 by 6.19 by 5.31 mm, and exhibits the precise geometry associated with a mixed brilliant cut that marries a brilliant star in the crown with controlled pavilion facet arrays. The cutter retained a relatively deep profile, with a calculated depth of approximately 75 percent, which concentrates internal reflection and contributes to an even return of light across the table and crown facets. The mixed brilliant faceting pattern creates scintillation through a combination of small, angled crown facets that break light into bright flashes, and broader pavilion facets that emphasize depth and contrast. Polish is excellent, yielding crisp facet junctions and mirror like facet planes that enhance brilliance and preserve the stone's transparency. Color reads as light intensity blue, with an even saturation that remains delicate in tone, allowing the mixed cut to emphasize both sparkle and the stone's silvery blue character. The sapphire is untreated, no enhancement, and its provenance is Ceylon, Sri Lanka, a source known for producing stones with refined tone and attractive clarity.

At very slightly included clarity when evaluated at eye level, this sapphire carries a set of internal characteristics that serve as its unmistakable signature. Under magnification you can observe a constellation of pinpoint mineral crystals clustered near the pavilion and dispersed along certain facet junctions, these pinpoints act like micro reflectors that enhance scintillation rather than distract from clarity. Delicate, hair like silk inclusions align in fine parallel arrays, oriented with the crystallographic growth, and they create a subtle satiny effect when light travels through the pavilion, adding a soft internal glow to the blue. A narrow feather is confined close to the girdle, and it is rendered inconspicuous by the excellent polish and the strategic facet angles, it functions as a light diffuser in certain viewing orientations, producing a slightly softer flash that complements the brilliant facets. These inclusions together form a reproducible internal fingerprint, a pattern that confirms natural origin and provides uniqueness for identification. The Natural Sapphire Company presents this untreated Ceylon sapphire as a collector grade gem that balances technical cut quality, natural internal character, and an elegant lightness of color, making it ideal for precision settings where both optical performance and natural signature are valued.
