3.68 Ct. Blue Sapphire from Ceylon (Sri Lanka)

This heart shape blue sapphire weighs 3.68 carat and measures 10.00 x 10.19 x 5.12 mm, a precise dimensional profile that suits both solitaire and halo mounting options. The cutter employed a mixed brilliant cut schema, combining a brilliant faceted crown with a modified pavilion to maximize return of light in a non standard outline. Facet junctions are tight and the polish is excellent, which enhances facet contrast and yields crisp windowing when the stone is viewed face up. Transparency is high, and the clarity grade is slightly included, evaluated at eye level, with natural crystal and rutile inclusions that are positioned so they do not disrupt the overall face up brilliance. Color presents at a vivid intensity, a saturated Ceylon blue that displays subtle velvety zones under different lighting angles. The proportioned depth of 5.12 mm supports a strong table to pavilion relationship, preserving both color saturation and lively scintillation. Enhancement is heat treated, a stable and industry accepted process that optimizes blue hue and reduces masking by brownish undertones without introducing foreign materials. The gem is sourced from Ceylon, Sri Lanka, which is reflected in the balance of vivid blue saturation and silky clarity characteristics typical of that provenance. The stone is finished to be setting ready, with crisp girdle symmetry and a heart silhouette executed to emphasize symmetry of the lobes and a well defined cleft.

When comparing this natural Ceylon sapphire to lab grown gemstones, several material and market distinctions become evident. Natural sapphires record a unique growth history in their inclusion patterns and trace element chemistry, which serve as immutable fingerprints for origin verification and long term valuation. Lab grown sapphires can mimic color and clarity, yet they lack the stochastic inclusion topology and rare trace signatures that collectors and connoisseurs prize. From a craftsmanship perspective, cutting a natural sapphire requires adaptive planning to work with internal features and maximizes yield, a process that preserves weight and yields a stone with personality and provenance. Natural stones historically retain greater secondary market value and desirability for bespoke pieces, particularly when documented by a reputable firm. At The Natural Sapphire Company we highlight the combination of geological rarity, documented origin, meticulous cutting, and stable heat enhancement as the advantages that make this 3.68 carat Ceylon heart shape sapphire a technically superior and enduring choice compared to its laboratory grown counterparts.
