1.17 Ct. Blue Sapphire from Ceylon (Sri Lanka)

This specimen from The Natural Sapphire Company is a transparent, round shape blue sapphire, weighing 1.17 carats, with dimensions of 6.30 by 6.21 by 3.80 millimeters, presented in a mixed brilliant cut, with a clarity grade of very slightly included as evaluated at eye level, a vivid color intensity, and an excellent polish. The stone is heat treated, a standard and stable enhancement, and its origin is Ceylon, Sri Lanka. These objective attributes define the gem as a refined example of Sri Lankan material, combining a clean eye level appearance with a focused and lively coloration. The mixed brilliant cut preserves the round silhouette preferred for many classic settings, while the cut geometry and polish work together to maximize both color and light return.

The color of this sapphire is the most distinguishing attribute, and it will stand out in any jewelry setting due to its vivid intensity and transparent body. The vivid blue displays depth without appearing overly dark, and the transparent nature of the crystal allows light to penetrate and reflect from internal facets, creating scintillation and a saturated appearance across viewing angles. The mixed brilliant faceting pattern contributes to a balanced distribution of light and color, so that the blue reads consistently on the table area, on the crown, and around the girdle. In practical terms, the gem projects a clear and lively blue that is noticeable from a distance, and on closer inspection reveals subtle variations in tone that accentuate the cut and the internal structure, enhancing the overall presence when set into metal and worn.

From a setting and design perspective, this 1.17 carat round sapphire and its specific measurements make it highly versatile for a range of jewelry types, including single stone rings, classic solitaires, halo designs, small pendants, and refined stud earrings. The near symmetrical proportions indicated by the 6.30 by 6.21 millimeter dimensions enable precise setting work, and the 3.80 millimeter depth offers sufficient pavilion volume for optical performance without overwhelming the mounting. The vivid blue color will interact differently with various metals, offering design flexibility, where white gold and platinum tend to emphasize the sapphire s cooler, more saturated facets, and warm yellow gold can create a complementary contrast that accentuates the stone s richness. The sapphire s hardness, as corundum, is a durable choice for frequent wear, retaining polish and resisting abrasion in daily use, while the very slightly included clarity at eye level provides a clean visual field that supports both set and unset presentation.

Careful handling and appropriate setting will preserve the stone s visual qualities, and the documented heat treatment applied to this sapphire is a stable enhancement commonly used to improve color and clarity, and it does not require special ongoing treatment beyond standard gem care. Routine cleaning with warm, soapy water and a soft brush will maintain the surface polish and color saturation, and professional inspection during setting and after any significant impact is recommended to ensure the mounting remains secure. For bespoke design work, precise measurements and the mixed brilliant cut information can be used by jewelers to calculate bezel thickness, prong placement, and gallery depth to accommodate the gem s proportions while showcasing the vivid blue face up. For technical inquiries or to arrange a viewing, specialists at The Natural Sapphire Company can provide additional details, documentation, and guidance to ensure that this sapphire performs as intended in its final setting.
