1.37 Ct. Blue Sapphire from Ceylon (Sri Lanka)

This oval, transparent, certified blue sapphire presents a considered combination of classic proportion and contemporary character, offered by The Natural Sapphire Company. The gem weighs one point three seven carats, with dimensions of seven point four eight by five point five eight by three point seven eight millimeters, and it is executed in an oval silhouette that balances presence with versatility. The mixed brilliant cut has been employed to optimize balance between scintillation and color saturation, and the cutter has retained depth in the pavilion to preserve the gem s natural tone and body color. Clarity is graded as very slightly included when evaluated at eye level, and the facet junctions demonstrate an excellent polish, delivering clean reflections and a refined overall finish. The stone has been heat treated, an accepted enhancement that stabilizes color and improves visual uniformity, and the sapphire s origin is Ceylon Sri Lanka, a provenance associated with a long tradition of fine blue sapphires.

The most distinguishing attribute of this sapphire is its vivid color intensity, a rich and bold blue that reads as deep cobalt with occasional inky navy flashes in stronger light. The saturation is notable for its evenness across the table and crown, and the hue remains true from multiple viewing angles, allowing the stone to convey steadiness and presence without appearing overly dark. This rich, bold color functions on more than a purely aesthetic level, serving as a symbol of personal power and distinction. When set in jewelry, the sapphire projects a composed confidence, complementing attire and bearing without overwhelming the wearer. Its color is sufficiently dramatic to serve as a focal point, yet refined enough to pair with both warm and cool metal tones, offering design flexibility for classic solitaire settings, three stone arrangements, or asymmetric contemporary mounts.

From a gemological and engineering perspective, the mixed brilliant cut of this oval sapphire contributes to measured light return and a balanced face up appearance. The cut planning preserved critical weight while allowing for lively internal reflections, which accentuate the vivid blue and permit flashes of lighter cornflower blue in areas where the crown facets catch direct light. The very slightly included clarity grade indicates the presence of minor natural features that are not visible at a normal viewing distance, and these subtle inclusions do not interrupt the visual continuity of color or reduce durability. The excellent polish emphasizes crisp facet planes and minimizes surface disturbances, which supports a high degree of brilliance and a smooth tactile sensation against a mounting. Heat treatment, applied in a controlled manner, enhances the stone s saturation and transparency while respecting its natural character and origin, consistent with industry standards for presenting stable and attractive sapphires for wearable jewelry.

Provenance and responsible sourcing are integral to the character of quality gemstones, and this sapphire s identification to Ceylon Sri Lanka is an important element of its story. Sapphires from this region frequently display a particular combination of clarity and vividness that is prized by connoisseurs and designers alike, and the certificate accompanying the stone documents its essential attributes for assurance and transparency. The Natural Sapphire Company supports considered selection and long term enjoyment, and we provide detailed documentation and guidance on setting options, care, and maintenance. For daily wear, routine cleaning with warm water and a mild detergent, a soft brush, and occasional professional inspection is recommended to preserve polish and secure the mount, and the sapphire s durable corundum composition makes it suitable for engagement rings and heirloom pieces intended for regular use.

In summary, this one point three seven carat oval blue sapphire offers a refined interplay of vivid color, professional cutting, and durable clarity, embodying a bold color that symbolizes personal power and distinction. Its proportions and excellent polish enable consistent face up performance, while the heat treatment and Ceylon Sri Lanka origin provide context for its visual attributes. Presented by The Natural Sapphire Company, the gem is accompanied by certification and professional guidance, supporting an informed choice for those seeking a sapphire that merges aesthetic presence with practical wearability.
