1.57 Ct. Yellow Sapphire from Ceylon (Sri Lanka)

This loose gem is a transparent yellow sapphire, weighing 1.57 carat, presented in a round shape with precise dimensions of 7.19 by 7.16 by 4.14 millimeters, cut in a mixed brilliant style to balance scintillation and face up color, graded as very slightly included at eye level, showing intense color intensity and an excellent polish, untreated and free of enhancement, originating from Ceylon Sri Lanka, offered by The Natural Sapphire Company. The mixed brilliant cut combines a brilliant crown arrangement with a faceted pavilion, which concentrates return of light while preserving weight, and the excellent polish ensures that the facets remain crisp, supporting maximum brilliance and consistent color presentation. The eye level clarity description very slightly included indicates that the stone is effectively clean to most observers when viewed without magnification, with minor internal characteristics that do not detract from overall transparency or visual appeal. The combination of intense natural color and an absence of enhancement is characteristic of fine Ceylon material, providing a vivid yellow saturation that remains stable under normal conditions.

In terms of durability this sapphire is well suited to daily wear, due to the inherent physical properties of corundum. Sapphire rates nine on the Mohs hardness scale, making it one of the hardest gemstones available after diamond, and capable of resisting scratches from virtually all everyday materials, which is a primary factor in maintaining long term polish and facet integrity. Corundum also exhibits favorable toughness relative to many other gem materials, meaning that it resists cleavage and chipping under ordinary use, though like all gemstones it is not impervious to hard knocks on metal edges. The mixed brilliant cut and excellent polish contribute to practical performance because clean facet junctions and stable facet planes reduce sites for abrasion to develop, and the eye clean nature reduces the likelihood that inclusions will propagate as weaknesses. For routine maintenance simply cleaning with warm water, a mild detergent and a soft brush will remove surface residues and restore brilliance, and because this sapphire is untreated, standard gem care protocols apply. Ultrasonic cleaning is generally acceptable for clean, intact sapphires, however inspection for surface reaching fractures or mounted settings with delicate components should precede the use of mechanical cleaning methods.

For setting and long term stewardship consider approaches that maximize both protection and display, depending on the intended piece of jewelry. Bezel settings offer continuous metal protection around the girdle and are recommended for pieces subjected to rougher wear such as rings or bracelets, while secure multi prong settings will retain a more open profile to display the mixed brilliant pavilion and crown, emphasizing scintillation and face up color. Because this sapphire is free of enhancement and originates from Ceylon Sri Lanka, its natural provenance supports both aesthetic and conservation considerations when selecting an heirloom quality mount, and the stone is well suited to engagement rings, daily pendants, and robust cocktail pieces alike. The Natural Sapphire Company is available to provide detailed condition reports and mounting recommendations, including options for lifetime care and re polishing should future conservation be desired. With routine care, appropriate setting, and periodic professional inspection, this 1.57 carat Sri Lankan yellow sapphire will retain its color, fire, and structural integrity for generations, offering a durable natural gem that integrates reliably into everyday jewelry without compromising visual performance.
