1.21 Ct. Color Change Sapphire from Ceylon (Sri Lanka)

This GIA certified, 1.21 carat round sapphire presents a transparent, bluish violet to purple color change, with precise dimensions of 6.73 by 6.63 by 3.50 millimeters. The stone is faceted in a mixed brilliant style, combining a brilliant crown to maximize scintillation and a faceted pavilion geometry tuned to retain saturation and controlled light return. The cut yields a depth of approximately 52.4 percent, a proportion that balances face up brightness with color saturation, and the excellent polish enhances facet crispness and spectral flashes. Clarity is graded slightly included when evaluated at eye level, with inclusions that do not interrupt the stone face up transparency or its strong color change. This sapphire is unenhanced, origin Ceylon Sri Lanka, and its cutting orientation was executed to emphasize pleochroic axes, so the stone shifts from a cooler bluish violet under daylight to a warmer purple in incandescent lighting, an effect that is both predictable and visually persuasive.

For custom jewelry, this sapphire responds exceptionally well to settings and companion stones that either increase contrast or reinforce its purple spectrum. A narrow halo of high color grade white melee diamonds will raise apparent brightness and add isolated white light return, while maintaining the sapphire as the visual anchor. For chromatic harmony, small pink sapphires or violet spinels set as shoulders will deepen the overall purple narrative without competing with the primary stone. For complementary contrast, green stones such as tsavorite garnet or emerald create a lively color opposition that accentuates the sapphire purple, useful in three stone or cluster arrangements. Metal selection alters perceived hue, with platinum or 18 karat white gold emphasizing the cooler bluish notes, and 18 karat rose gold warming the face up purple. The mixed brilliant cut delivers pronounced facet scintillation, so open prong settings or a low bezel that allows light ingress will optimize the dynamic color change. The Natural Sapphire Company can design a custom mounting that leverages these optical attributes, specifying companion gem sizes and precise setting geometry to preserve the stone integrity while maximizing visual impact.
