1.07 Ct. Blue Sapphire from Ceylon (Sri Lanka)

This transparent blue sapphire is precisely cut and calibrated, a 1.07 carat oval with dimensions measuring 7.11 by 4.97 by 3.82 millimeters. The stone has a mixed brilliant cut that balances pavilion depth and crown facets to optimize light performance, and it is finished to an excellent polish. Clarity has been evaluated at eye level as very very slightly included, indicating minimal internal features that do not compromise transparency or visual appeal. Color is classified at medium intensity, displaying the classic Ceylon blue hue associated with Sri Lankan sapphires, and the piece is untreated with no enhancement reported. The provenance is Ceylon, and this gem is presented with technical and provenance information in keeping with The Natural Sapphire Company standards.

The mixed brilliant cut of this oval sapphire is selected to increase scintillation while preserving a clean face up appearance, making the best use of the stone’s optical properties. With a balanced table and well proportioned pavilion, the stone returns light evenly across its surface, producing lively flashes without dark zones. The medium color intensity provides a pleasing saturation that reads as vivid in daylight and remains well defined under artificial lighting. The clarity assessment at eye level, together with the excellent polish, means the gem offers both transparency and surface perfection that contribute to strong brilliance and visual depth for ring, pendant, or earring applications.

From a durability perspective this sapphire is well suited to daily wear. Sapphire is a corundum mineral with a hardness of nine on the Mohs scale, second only to diamond, and it exhibits strong resistance to scratching and abrasion under ordinary use. The stone’s toughness and lack of significant surface reaching fractures reduce the risk of chipping when set in protective mounting styles. For everyday pieces such as engagement rings and daily pendants, secure settings with well maintained prongs or a protective bezel will minimize exposure to impact, and a low profile can reduce leverage on the mounting. Routine inspection of the setting and prompt attention to loose claws will preserve the integrity of the piece over years of regular wear.

Care and maintenance are straightforward and conservative. Regular cleaning using warm water with a mild detergent and a soft brush will keep the sapphire bright, and dry cleaning with a soft lint free cloth will maintain polish. Ultrasonic cleaning and steam cleaning are frequently used by professionals for natural, unheated sapphires that have no significant fissures, yet individual stones vary and a brief consultation with The Natural Sapphire Company can confirm the safest method for this specific gem. Avoid prolonged exposure to strong acids, abrasives, and harsh household chemicals, and remove the piece during heavy manual work to limit risk of impact. With its robust material properties, straightforward care needs, and detailed documentation of origin, cut, and condition, this 1.07 carat Ceylon oval sapphire is a technically sound choice for jewellery intended for regular wear, and The Natural Sapphire Company can provide additional technical details and mounting recommendations upon request.
