1.03 Ct. Blue Sapphire from Ceylon (Sri Lanka)

One beautiful transparent 1.03 carat round blue sapphire, measuring 5.63 x 5.63 x 3.90 mm, presents a refined combination of size and optical quality. The gem is fashioned in a mixed brilliant cut, and displays a vivid color intensity with an excellent polish that enhances its face up saturation and scintillation. Clarity is graded as very slightly included when evaluated at eye level, indicating that inclusions are minimal and do not detract from the gems visual impact under typical viewing conditions. No enhancement has been applied to this stone, and its origin is Ceylon, Sri Lanka, a region long known for producing sapphires with lively, saturated blues and attractive clarity. The overall transparency and cut precision contribute to balanced light return, allowing the blue hue to read evenly across the table without patchy zones.

The combination of the sapphires physical measurements and its clarity makes it particularly well suited as a statement piece, despite the modest scale of one carat. The diameter of 5.63 millimeters yields a face up presence that is proportionally strong, and the pavilion depth of 3.90 millimeters produces an overall depth ratio of about 69 percent, a proportion that supports both color saturation and brilliance in a mixed brilliant profile. The mixed brilliant cut concentrates light toward the table while the excellent polish minimizes surface diffusion, so the gem presents lively flashes and a dense, vivid blue at first glance. Because the clarity is described as very slightly included at eye level, the stone maintains an open, clean appearance to the naked eye, which amplifies its visual impact when set. In practical terms, the stone will command attention on the finger as a central element, and its color and clarity will read as a unified, bold expression rather than as a collection of small details.

For design and wear considerations, the sapphire is durable and versatile, appropriate for a range of settings that aim to emphasize its presence. Sapphire ranks nine on the Mohs scale, which makes this gem suitable for daily wear when set with appropriate protection and maintenance. The stone will function well as a solitary center stone in a solitaire mounting for a minimalist statement, as the focal point in a halo design to increase apparent scale and light play, or as the primary gem in a three stone composition to balance visual weight and narrative. The lack of enhancement is significant for collectors and clients who prioritize natural state gemstones, and the Ceylon origin contributes to provenance value and appeal. The Natural Sapphire Company provides full disclosure of origin and treatment status, and can assist with certification, bespoke setting options, and recommendations for secure mounting that preserves the sapphires optical attributes.

Care guidance and final recommendations are straightforward and intended to preserve the sapphires clarity and finish. Routine cleaning with warm water, a mild detergent, and a soft brush will maintain surface sheen, and professional cleaning or inspection is advised periodically to confirm prong security and to evaluate any potential damage from wear. Ultrasonic cleaning and steam should be approached with caution in general for sapphires with significant internal features, although this particular stone is untreated and presents minimal visible inclusions. For clients seeking a confident, refined statement piece that reads boldly on the finger, this 1.03 carat round Ceylon sapphire combines measurable presence, clear face up appearance, and natural untreated provenance, and can be supplied with documentation and setting support through The Natural Sapphire Company.
