1.13 Ct. Blue Sapphire from Ceylon (Sri Lanka)

Across the centuries the blue sapphire has been a symbol of nobility, wisdom, and eternal constancy, treasured by kings and worn by priests long before modern gemology could catalogue its many virtues. From the ancient mines of Ceylon Sri Lanka, where some of the most sought after sapphires have been found, comes a single, luminous example that speaks to that same lineage. The Natural Sapphire Company is proud to present a transparent round blue sapphire that carries the quiet authority of history together with the precision of contemporary cutting and grading. This gem is not merely an ornament, it is a continuation of a story that has been told in coronets and signet rings, in devotional jewels and in the private collections of those who value continuity and legacy.

Weight is the language by which rarity and value speak most plainly, and the 1.13 carat weight of this sapphire is central to its significance. In the realm of natural sapphires each additional tenth of a carat increases desirability in a way that is not strictly linear, because larger single stones are exponentially rarer than their smaller counterparts. A 1.13 carat stone sits in a sweet place for collectors and connoisseurs, large enough to command presence in a classic solitaire or cluster design, yet still refined enough to be set with deliberate restraint. The carat figure is also a measure of the gem material itself, reflecting the marble of deep formation pressures and geological time that produced this vivid blue crystal. For those who understand the market, a well colored eye clean sapphire over one carat from Ceylon Sri Lanka is a piece that is already scarce, and likely to become more so with time.

Beyond weight the proportions and finish of a gem determine how its internal life is released into light, and this 1.13 carat sapphire has been faceted in a mixed brilliant cut to maximize fire and brilliance while preserving the depth of color for which Ceylon sapphires are celebrated. Measuring 5.40 by 5.45 by 4.62 mm, the stone presents an ideal balance of diameter and depth, dimensions that translate into a visually pleasing face up size while allowing the pavilion facets to return light with lively scintillation. The clarity has been evaluated as eye clean at normal viewing distance, meaning the field of view is free from distractions and the deep, vivid color may be appreciated without interruption. The polish is excellent, a mark of patient lapidary work that allows facet junctions to sit crisp and bright, and the overall transparency ensures that light courses through the gem rather than being absorbed in dull zones.

This sapphire has been heat treated, a traditional and widely accepted enhancement that stabilizes and intensifies color while leaving the gem fundamentally natural, a common practice especially for stones originating in the renowned Ceylon Sri Lanka deposits. Heat treatment in the hands of careful cutters is an age old technique that harmonizes the gemotype without compromising its geological provenance, a detail that serious collectors see as part of a transparent and ethical trade. When set in a classical mounting the 1.13 carat round will offer a balance of modesty and impact, sitting serenely on the hand while revealing a surprisingly commanding presence under both daylight and evening illumination. For those designing an engagement ring, a signet or a pendant with the intention of passing it along as an heirloom, the mixed brilliant cut and the eye clean clarity ensure the gem will age with dignity and maintain the clarity of its story.
