2.25 Ct. Blue Sapphire from Ceylon (Sri Lanka)

This sapphire presents as a transparent, cushion shaped gem weighing 2.25 carats, with dimensions of 7.95 by 5.97 by 5.17 millimeters. The cut is a mixed brilliant, combining a pavillion of brilliant facets with a more classical crown, yielding a balance of depth of color and lively scintillation. Clarity is graded as slightly included when evaluated at eye level, indicating the presence of minor inclusions that do not materially detract from the overall transparency or visual appeal. Color is classified as intense, providing a rich, saturated blue characteristic of fine Ceylon, Sri Lanka origin material. Surface condition is described as excellent polish, which enhances both light return and resistance to superficial abrasion. The stone has been heat treated, a stable and commonly accepted enhancement for sapphires that optimizes color and clarity without compromising the structural integrity of corundum. This description is provided by The Natural Sapphire Company, noting full provenance and treatment disclosure.

From a durability perspective, this sapphire is exceptionally well suited to daily wear. Sapphire is a variety of corundum, which rates nine on the Mohs hardness scale, second only to diamond, providing strong resistance to scratching from most materials encountered in everyday activities. The measured depth, approximately five point one seven millimeters relative to the length of seven point nine five millimeters, produces a depth ratio in the range that preserves structural proportion and reduces the likelihood of thin girdle stress. Slight inclusions noted at eye level are not indicative of significant fissures or cleavage planes that would compromise toughness, and heat treatment carried out to enhance color is a thermal process that does not weaken the crystal lattice. The excellent polish contributes to surface durability, lowering the propensity for micro abrasions to accumulate and dull the finish over time. Collectively these factors result in a gem that retains stability under normal wear conditions.

Practical considerations for daily jewelry use include setting choice, protective measures, and the types of pieces that best showcase the sapphire while mitigating risk. For rings subject to frequent contact, protective settings such as a full bezel or partial bezel offer additional security by shielding the girdle and crown from direct impact, while four or six prong settings can offer a good balance between protection and light exposure when the prongs are robust and correctly positioned. The cushion shape and mixed brilliant cut present a pleasing face up area and depth, making the gem appropriate for engagement rings, daily wear cocktail rings, pendants, and bracelets. For high impact activities or professions involving repeated mechanical contact, a pendant or a bezel set ring will reduce exposure to knocks and potential chipping. The intrinsic hardness of sapphire will resist surface scratches from most materials, but care should be taken to avoid contact with materials of equal or greater hardness, and to avoid hard blows to the stone that could transfer stress to internal inclusions.

Recommended care practices will preserve the appearance and function of the stone over many years. Routine cleaning with warm water, a mild detergent, and a soft brush will remove residues that can diminish luster, followed by a careful rinse and gentle drying with a soft cloth. Ultrasonic and steam cleaning are generally safe for heat treated sapphires that do not contain fracture filling, however, because the clarity is slightly included, any decision to use these methods should be preceded by a professional assessment to confirm there are no vulnerable fissures. Avoid exposure to strong acids, alkalis, household cleaners that contain harsh abrasives, and prolonged contact with cosmetics and lotions that can leave films on the polished surface. Periodic inspection by a qualified jeweler will ensure settings remain secure and will identify any need for prong tightening or reflowing, especially in pieces worn every day. When not in use, store the sapphire separately in a soft pouch or compartmentalized jewelry box to prevent contact with harder gemstones.

The provenance of this stone from Ceylon, Sri Lanka contributes to its desirability, as material from that region is known for vivid, lively blue tones combined with a certain depth of color that balances vibrancy with clarity. The treatment history of heat only is both industry standard and stable, and the combination of excellent polish and a well executed mixed brilliant cut maximizes optical performance while maintaining the robustness necessary for daily wear. The Natural Sapphire Company provides full documentation regarding origin and treatment, and can advise on specific mounting options and maintenance protocols to align with individual wear patterns. In summary, this 2.25 carat cushion shaped blue sapphire combines high hardness, solid structural proportions, stable enhancement history, and careful cutting and polishing, making it well suited to be set into jewelry intended for everyday use, provided standard protective practices and routine care are followed.
