1.04 Ct. Blue Sapphire from Tanzania

One beautiful transparent 1.04 carat cushion shape blue sapphire, with exact dimensions of 6.29 x 4.74 x 3.74 mm, presents a balanced combination of presence and practicality for use in fine jewelry. Cut in a faceted style with a mixed brilliant arrangement, this stone exhibits controlled light return and scintillation while maintaining a classic cushion silhouette. The color intensity is described as intense, producing a vivid blue that remains consistent through different viewing angles and lighting conditions. Clarity is graded slightly included at eye level, and the internal characteristics are modest in size and distribution, visible only under careful inspection and not detracting from the gem central appeal. The surface finish is of excellent polish, yielding crisp facet junctions and a smooth table that enhances both brilliance and ease of cleaning. Origin is Tanzania, and there has been no enhancement or treatment performed on this sapphire, a detail that affirms its natural state and contributes to its rarity and appeal when evaluated by a professional gemological eye.

The physical properties of corundum render this sapphire particularly well suited to daily wear, and the stone in question benefits from those inherent attributes. On the Mohs hardness scale, sapphire registers at nine, second only to diamond in conventional jewelry materials, and this hardness translates into strong resistance to nicks and surface abrasion during routine activities. In addition to hardness, the material toughness of corundum is considerable, and the crystal structure lacks the easy cleavage planes found in other gem species, meaning that the risk of catastrophic cleavage under impact is low. The slightly included clarity grade reported here does not indicate structural weakness, as inclusions are stable and do not form stress concentrators in the way that fractures might. The excellent polish and well executed mixed brilliant cutting style further protect the gem visually and physically, by minimizing micro abrasions and by distributing light in a manner that reduces the visibility of minor internal features. These combined factors make this 1.04 carat Tanzanian cushion sapphire an excellent candidate for everyday pieces such as rings, pendants, and bracelets, provided that appropriate setting techniques are used to protect the girdle and corners.

Recommended mounting and care practices maximize longevity while preserving the stone aesthetic. For daily wear in a ring, settings that provide protective profiles, such as a full or partial bezel, or well positioned prongs with a secure seat for the cape cushioned corners, reduce the chance of edge impacts. A low profile setting reduces the likelihood of catching while performing manual tasks. Routine cleaning with warm water and a mild detergent, applied with a soft brush and followed by gentle drying with a soft cloth, will maintain the excellent polish and restore brilliance without risk to the stone integrity. Ultrasonic cleaners may be used with caution and professional guidance, especially where a mounting is present, but are generally acceptable for untreated sapphire material. Regular inspection by a jeweler ensures that prongs remain secure and that the setting continues to shield the gem effectively. The Natural Sapphire Company offers this sapphire in its natural, untreated condition, and documentation regarding its origin, weight, dimensions, and the absence of enhancements accompanies the gem to support informed decisions regarding setting and long term care. This stone combines a durable material profile with a refined cut and intense color, making it a practical and elegant choice for jewelry intended for daily wear.
