3.52 Ct. Blue Sapphire from Ceylon (Sri Lanka)

This oval shape blue sapphire is a GIA certified Royal Blue gemstone, weighing 3.52 carats, and measuring 10.52 millimeters by 8.57 millimeters by 4.96 millimeters. The stone is transparent, with a vivid color intensity and excellent polish. The clarity has been evaluated as very very slightly included, assessed at eye level, indicating that any internal features are minimal and have limited impact on the overall transparency and visual appeal. The sapphire is heat treated to improve color and clarity, and its stated origin is Ceylon, Sri Lanka. The gem is presented and documented by The Natural Sapphire Company, with certification that supports the stone characteristics described.

The mixed brilliant cut applied to this oval sapphire combines a standard brilliant facet pattern on the crown with a complementary pavilion geometry designed to maximize internal reflection and light return. The crown faceting, incorporating triangular and kite shaped facets, directs incident light into the gem core, while the pavillion facets are oriented to reflect that light back through the table and crown facets. The result is a controlled balance of light return and colored saturation, with the oval outline offering elongated facet planes along the shoulders that enhance movement. The measured depth of 4.96 millimeters yields a proportion that is approximately 52 percent when compared to the average of the length and width. This depth supports efficient prisming and scintillation without excessive windowing or dark banding, and the excellent polish contributes to crisp facet junctions and minimal light leakage.

Optically the sapphire exhibits a lively interplay between strong color concentration and bright flashes of light. The vivid Royal Blue hue remains consistent through the table and crown, while the mixed brilliant faceting produces a pattern of scintillation that animates as the stone or viewer moves. Contrast between bright facet flashes and deeper blue areas creates visual depth and a sense of three dimensionality, and the transparency of the material allows for clear, saturated color to be observed even under daylight conditions. In lower light, the heat treated color stability and the faceting geometry maintain attractive blue saturation and controlled sparkle. The clarity grading at eye level means most observers will perceive a clean, open appearance, while the presence of very minor inclusions can contribute to natural character without compromising brilliance.

From a practical standpoint this 3.52 carat oval sapphire is suitable as a center stone for a variety of jewelry applications, including rings, pendants, and bespoke pieces that benefit from an elongated oval footprint. The combination of vivid color, mixed brilliant faceting, and a well proportioned depth makes the gem straightforward to set with minimal risk of optical disorientation once placed in a well designed mounting. Durability is consistent with corundum, and standard precautions for jewelry care, such as avoiding extreme heat or harsh chemicals and occasional professional cleaning, are appropriate. The Natural Sapphire Company provides full GIA documentation to verify the stone attributes and origin, and to assist in planning settings and appraisal. This description emphasizes the geometric faceting and optical performance that together produce maximum light play while preserving the sapphire character associated with classic Ceylon material.
