1.11 Ct. Purplish Blue Sapphire from Ceylon (Sri Lanka)

This purplish blue sapphire presents as a transparent, emerald cut gem weighing 1.11 carat, with exact dimensions of 7.46 by 4.83 by 3.15 millimeters. The stone exhibits the classic rectangular step cut geometry associated with the emerald cut, featuring a broad, open table and parallel crown and pavilion facets that emphasize color and clarity over scintillation. Measured proportions yield an approximate depth of 3.15 millimeters against an average girdle diameter of 6.145 millimeters, producing a depth to average diameter ratio of approximately 51.3 percent, a proportion range that preserves face up spread while maintaining sufficient pavilion depth for strong light return. The relationship between length and width creates an elegant, elongated face up that reads larger than the nominal carat weight alone would suggest, and the cutting proportions have been executed to balance spread and structural integrity, offering a substantial visual presence for use as a center stone in an engagement setting.

Color character is a defining attribute of this sapphire, recorded as purplish blue with vivid color intensity, a combination that indicates robust saturation with a medium dark tone that remains lively under varied lighting. Origin is Ceylon Sri Lanka, a source historically associated with lively cornflower and bluish violet tones, and this material displays that provenance signature in its optical response. The emerald cut is intentionally used to showcase that color consistently across the table plane, rather than fragmenting it with brilliant faceting, so the gem presents a stable, even color field when set. The stone has undergone heat treatment, a standard stabilization and enhancement practiced in the trade to improve color homogeneity and reduce specific inclusion visibility, and this treatment is permanent and widely accepted among connoisseurs. For engagement applications, consider metal choices and orientation that enhance the blue component, for example a platinum or white gold bezel or a cool tone halo to reinforce the blue, or a yellow gold setting to warm the purplish notes, while mindful that orientation of the pavilion axis can subtly alter perceived hue due to pleochroism inherent in corundum.

Clarity is graded very slightly included when evaluated at eye level, a term that denotes small inclusions that may be observed under careful direct viewing but do not materially undermine transparency or brilliance. In sapphires this level of clarity typically corresponds to fine needles or minute crystals distributed within the crystal lattice, and in this emerald cut those features are managed by facet placement and cutting orientation to minimize the appearance of any internal characteristics through the broad table. The gem’s excellent polish speaks to superior lapidary technique, with facet planes rendered smooth to optical tolerance and facet junctions meeting crisply, which maximizes clean light transmission and produces well defined internal reflections without surface disturbance. Attention to girdle thickness and facet alignment during cutting reduces stress concentration at points of setting contact, so the stone’s physical condition is suited to secure mounting without compromising the polish or facet integrity.

As an engagement choice this sapphire combines technical merit with enduring practicality, given corundum’s Mohs hardness of nine and its resistance to abrasion and daily wear, making it a reliable alternative to traditional diamond centers. The emerald cut profile lends itself to classic solitaire constructions, low profile bezels for active wearers, or architectural three stone designs with tapered baguette or trap cut diamond shoulders that echo the step facet pattern. For clients who prefer halo settings, a thin diamond halo will increase perceived size and add scintillation while preserving the sapphire’s color field, and for those seeking a minimalist aesthetic a four prong setting that secures the corners will display the table and highlight the stone’s elongated proportions. The Natural Sapphire Company stands behind provenance and craftsmanship, providing detailed reports on origin and enhancement, and we can advise on mounting tolerances, recommended bezel thickness, and compatible mounting metals to ensure the stone’s optical performance and long term security. For buyers seeking a technically refined center stone that balances vivid color, managed clarity, durable proportions, and classical step cut elegance, this 1.11 carat Ceylon purplish blue emerald cut sapphire represents an ideal engagement option, and our specialists are available to discuss setting specifications, accompany selection with certified documentation, and recommend complementary design elements to realize the intended aesthetic and functional objectives.
