1.31 Ct. Blue Sapphire from Ceylon (Sri Lanka)

Presenting one beautiful transparent 1.31 carat oval blue sapphire from Ceylon, offered by The Natural Sapphire Company. The gem measures 7.17 x 6.14 x 3.97 mm, and it has been expertly fashioned in a mixed brilliant cut that balances lively scintillation with rich face up color. Clarity is graded very slightly included at eye level, which means that to the unaided eye the stone appears clean and lively, while fine natural features remain under magnification as a hallmark of authenticity. The sapphire shows medium color intensity that sits in the most wearable and flattering range, retaining a clear blue saturation without tipping into overly dark or inky tones, and the polish is excellent so that each facet edge and table plane reflects light crisply. Heat treatment has been applied, a widely accepted and stable enhancement that improves blue tone and reduces distracting material, and it is fully disclosed. Unlike simple step cuts, the mixed brilliant combines a faceted pavilion and a carefully proportioned crown to maximize return of light while preserving weight and table size, a practical choice for a gem intended for regular wear. The modest carat weight combined with thoughtful proportions gives an excellent face up diameter, making the gem appear larger than its weight alone might suggest, and the corundum hardness of 9 on the Mohs scale provides far greater scratch resistance than most colored gems.

Placed in historical context, this Ceylon sapphire recalls some of the most celebrated blue gems while offering advantages that matter to contemporary owners. Sri Lanka is the historic source of many famous sapphires, including pieces like the Logan Sapphire in the Smithsonian and the Star of India, both of which helped define the world reputation for Ceylon blue. The Logan is admired for its vivid cornflower tone and transparency, and the Star of India amazes with its size and star effect, but those museum icons are often best appreciated under display lighting or in their sheer scale. This 1.31 carat oval delivers the pure color note that made those stones famous, while benefiting from an advanced faceting approach that converts color into vibrant scintillation and lively table brilliance. Many historical stones are admired at a distance or for their rarity, however a personally worn sapphire must perform close up, and this gem s very slightly included clarity and excellent polish ensure that its blue reads clean and consistent against skin, unlike older stones that reveal silk or zoning in ordinary light. In short, this sapphire channels the classic Ceylon character in a form that is suited to everyday elegance.

When compared to famous diamonds and other landmark gems, this sapphire offers a different and often superior proposition for clients who value color and practicality. Blue diamonds have headline appeal, yet sapphires return far more visible color per carat, and a Ceylon stone with medium intensity and transparent body will communicate vividness without requiring extreme scale. The mixed brilliant cut chosen here was specifically designed to maximize table sparkle while preserving weight and maintaining strong face up color, delivering a lively appearance that rivals finer cuts in optical performance. Heat treatment is an industry standard that The Natural Sapphire Company fully discloses, and it stabilizes hue and clarity so the gem will maintain its enhanced attributes under normal wear. Compared with many commercially marketed sapphires, this piece shows superior cut quality, cleaner face up appearance, and an overall finish that will age gracefully. The oval outline also affords design flexibility, working beautifully in classic solitaires, halo settings, and three stone arrangements that amplify perceived size and presence without sacrificing the stone s natural beauty.

This sapphire represents the best of both worlds, authentic Ceylon heritage and modern finishing that transforms mineral into a wearable treasure. At The Natural Sapphire Company we curate stones that reference historical prestige while delivering practical excellence, and this 1.31 carat oval is a prime example. It combines a flattering face up size, an excellent mixed brilliant cut, a transparency and clarity that read clean to the eye, and a medium color that flatters many skin tones. For those deciding between museum fame and daily wearability, this gem provides the romance of storied sapphires with the technical refinements that make a jewel enjoyable to wear every day. We provide full disclosure on origin and treatment, certification upon request, and personalized service to help you select a mounting that complements the gem s proportions and optical strengths.
