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

One transparent 1.10 carat round color change sapphire, dimensions 5.95 by 5.95 by 3.95 millimeters, mixed brilliant cut, presents a balanced combination of proportion and optical performance. The measured depth yields approximately 66 percent, a profile that supports strong face up presence while allowing secure setting options. Clarity is described as very very slightly included when evaluated at eye level, offering clean visual appeal under typical viewing conditions. Color shows medium intensity with a distinct change between lighting environments, exhibiting cooler bluish violet tones under fluorescent light and warmer purple tones under incandescent light. The polish is excellent, which preserves facet crispness and maximizes light return, and the stone is natural with no enhancement. Origin is Ceylon Sri Lanka, a provenance well regarded for fine sapphire material.

This sapphire is particularly well suited to custom jewelry due to its classic round shape and manageable size, which translate directly into design flexibility and predictable metal weight in bespoke settings. At just under six millimeters in diameter, the stone functions as an elegant solitaire in an engagement ring, a refined central gem in a halo composition, or a matched pair component for earrings when paired with complementary stones. The mixed brilliant cut enhances scintillation, making the color change effect lively as the wearer moves between different lighting conditions, and the modest depth supports both lower profile bezel designs and more prominent prong mounted options. Because the gem is untreated, its natural character adds design value for projects emphasizing authenticity and provenance. For precision work, the exact dimensions and exemplary polish allow accurate CAD modeling and consistent stone orientation during setting, and The Natural Sapphire Company can provide detailed imaging and measurements to assist bench jewelers and designers in achieving the intended visual outcome.
