1.61 Ct. Blue Sapphire from Ceylon (Sri Lanka)

This transparent blue sapphire presents as a round shape weighing 1.61 carats, with dimensions of 7.30 x 7.30 x 4.18 mm. The gem is fashioned with a mixed brilliant cut that balances faceting for both face up brilliance and depth of color. Clarity is graded as eye clean evaluated at eye level, indicating an absence of visible inclusions to the naked eye, and the surface finish is of excellent polish, contributing to clean light return across the table and crown facets. Color intensity is vivid, offering a strong, saturated blue that remains luminous under varied lighting conditions. Enhancement is heat treated, a widely accepted and stable treatment in the trade, and the sapphire is sourced from Ceylon, Sri Lanka, a provenance known for producing richly colored, high quality blue sapphires that display appealing saturation and clarity.

Optical performance for this stone is notable because the mixed brilliant cut maximizes scintillation while preserving the vivid Ceylon blue tone. The combination of precise faceting and an excellent polish allows facets to communicate light crisply, generating sharp flashes of brilliance and a lively play of blue tones. Transparency is high, which permits the eye clean clarity to contribute directly to a clean, vibrant appearance rather than being masked by surface haze or internal cloudiness. With a measured depth of 4.18 mm against a diameter of 7.30 mm, the depth proportion is approximately 57 percent, a figure that yields a balanced face up size and depth profile for secure mounting in a variety of jewelry settings.

As a gift this sapphire will make a striking and considered choice for someone special, because it combines the essential qualities that distinguish memorable gems. The vivid color provides immediate visual impact, the eye clean clarity offers confidence that the beauty will be evident without magnification, and the round mixed brilliant format is a timeless silhouette that works equally well in a classic solitaire ring, a refined pendant, or a pair of elegant stud earrings. The carat weight of 1.61 ensures a meaningful presence on the hand or at the throat, while the proportions and polish mean the stone sits attractively and reflects light effectively when set. Its Ceylon origin adds a narrative of provenance that many recipients appreciate, connecting the gem to a long history of Sri Lankan sapphire production.
