1.92 Ct. Blue Sapphire from Ceylon (Sri Lanka)

This transparent blue sapphire weighs 1.92 carats, and presents an elegant oval outline with precise dimensions of 8.43 by 6.81 by 4.05 millimeters. Originating from Ceylon Sri Lanka, this gem exhibits the hallmark qualities associated with Sri Lankan material, including a vivid chromatic response and pleasing transparency. The stone has been heat treated, a standard and stable enhancement used to intensify color and improve clarity, and it was evaluated as very slightly included when examined at eye level. The combination of weight, proportions, and visual clarity makes this sapphire a refined example of fine corundum, suitable for central use in bespoke settings or as part of a curated collection.

The mixed brilliant cut applied to this oval specimen is calibrated to optimize light performance across both the crown and pavilion facets, and it is responsible for the stone remarkable brightness and scintillation. Faceting has been balanced to deliver controlled light return, and the shallow to moderate pavilion depth yields an overall depth proportion of approximately 53 percent, which enhances face up spread while preserving depth for life and stability. The cut exhibits strong symmetry, and the facet junctions are executed to precise angles, producing lively flashes of blue and white as the sapphire is moved under different lighting conditions. The excellent polish further contributes to surface reflectivity and crisp facet contrast, reinforcing the gem exceptional cut and brilliance, making it a centerpiece in any collection.

Color presents as intense blue, with even saturation across the table and minimal zoning, permitting a consistent visual field when viewed face up. The intensity is concentrated enough to read as a true sapphire blue, without veering into overly dark tones that can reduce apparent size, and the tone sits in a range that remains versatile for multiple metal choices and design approaches. Clarity is classified as very slightly included evaluated at eye level, which indicates minor natural inclusions that do not disrupt the overall transparency or the gem ability to transmit and reflect light. These inclusions are typical of natural corundum, and they do not compromise structural integrity or the gem aesthetic. The documented heat treatment is stable and permanent, and it is disclosed here as part of the complete assessment of the stone.

Practical considerations for mounting and care are straightforward, and the sapphire responds well to common jewelry fabrication practices. Its oval shape and polished girdle make it well suited to solitaire rings, three stone mounts, understated bezels, or halo settings that emphasize center presence. When set with the table oriented to maximize face up exposure, the stone displays optimal brilliance and color saturation, and the mixed brilliant faceting provides attractive scintillation under both artificial and natural illumination. Routine maintenance consists of gentle cleaning with warm soapy water and a soft brush, avoiding harsh chemicals or sudden temperature shock. The Natural Sapphire Company documents provenance and treatment history for this gem, and recommended practices for secure setting and conservation are available upon request. The combination of precise cutting, intense color intensity, transparent clarity, and excellent polish establishes this 1.92 carat oval Ceylon sapphire as a distinguished gem for discerning collectors and designers, making it a centerpiece in any collection.
