1.52 Ct. Blue Sapphire from Africa

This transparent blue sapphire weighs 1.52 carat, and is fashioned in a cushion shape with precise dimensions of 7.08 x 5.66 x 4.16 mm. The gem features a mixed brilliant cut designed to balance face up color and internal brilliance, and it presents a vivid color intensity that reads as true blue under standard viewing conditions. Clarity is graded as slightly included when evaluated at eye level, indicating minor internal characteristics that do not detract from the overall visual appeal, and the surface finish has been brought to an excellent polish to maximize light return. Enhancement has been applied through heat treatment, a widely accepted and stable practice used to improve color uniformity. The origin of this sapphire is Africa, a source known for producing stones with rich blue hues and natural transparency.

The journey of this sapphire begins at its African mining locale where careful extraction and initial sorting distinguish gem quality material from lower grade rough. From the mine the rough is assessed by experienced graders who consider color saturation, crystal habit, and potential yield, then the chosen piece is guided to a cutter whose skill determines the final shape and optical performance. In this case the cutter selected a cushion silhouette with a mixed brilliant pavilion to preserve weight while enhancing brilliance and color saturation, an approach that respects the original rough and optimizes the finished proportions. After faceting the stone was meticulously polished to achieve an excellent surface finish, and clarity was evaluated at eye level to provide an honest assessment of visible inclusions. Heat treatment was applied under controlled conditions to stabilize and intensify the natural blue, followed by a final quality review that recorded weight, dimensions, cut type, clarity observations, color intensity, polish quality, treatment, and origin.

The Natural Sapphire Company oversees the final stages of introduction to market, applying independent verification protocols and documented provenance to ensure confidence for the buyer. Each specification is recorded and communicated in a straightforward manner, allowing jewelers and collectors to understand the gem on technical terms. The result is a transparent account of a single 1.52 carat cushion blue sapphire, a gem whose physical attributes and documented journey from African source to market reflect deliberate decisions made to present its natural beauty with integrity and clarity.
