1.58 Ct. Bluish Purple Sapphire from Ceylon (Sri Lanka)

One transparent cushion shape bluish purple sapphire weighing 1.58 carats presents a well balanced combination of color and proportion, measuring 7.62 by 5.87 by 3.83 millimeters. The stone is faceted with a mixed brilliant cut, providing lively scintillation and controlled light return across the table and pavilion. Clarity is graded slightly included, evaluated at eye level, with inclusions that do not materially interrupt the overall transparency. Color is medium in intensity, showing an even bluish purple tone that reads with pleasing subtlety under a range of lighting conditions. The gem has an excellent polish, which enhances surface brightness and complements the mixed brilliant facet arrangement. The sapphire is heat treated, a stable and widely accepted enhancement for sapphires, and it originates from Ceylon Sri Lanka, a source known for producing sapphires with attractive hue profiles and eye clean characteristics. The Natural Sapphire Company endorses the gem as meeting rigorous standards for cut quality and finish.

In terms of durability the material properties of sapphire make this stone particularly well suited to daily wear, corundum registers at nine on the Mohs hardness scale, second only to diamond among commonly used gem materials. This high hardness translates to strong resistance to scratches and abrasion from everyday contact, while the excellent polish helps maintain luster over time. The mixed brilliant cut yields durable facet junctions and a proportion profile that can be securely set in a variety of mounting styles without compromising structural integrity. Heat treatment applied to this sapphire is a stable enhancement when properly executed, and does not reduce the intrinsic hardness of the host mineral. For added protection in daily wear settings, conventional practices such as selecting secure prong placements or a bezel setting can help shield the girdle and crown from direct impact, preserving the gem over long term use. The combination of quality cutting, superior polish, and the innate toughness of Ceylon corundum makes this 1.58 carat cushion sapphire a practical choice for everyday rings, pendants, and other jewelry pieces, supported by the documentation and expertise of The Natural Sapphire Company.
