4.78 Ct. Bluish Green Sapphire from Madagascar

This 4.78 carat cushion shape sapphire from Madagascar presents a balanced combination of color, clarity, and cut, dimensions 11.62 x 9.69 x 4.72 mm, transparent with a bluish green hue and medium color intensity. Cut to a mixed brilliant cut, the pavilion employs step and brilliant facet geometry to maximise both depth of color and light return, while the crown facets are proportioned to control windowing and enhance scintillation. The result is a stone that displays controlled brilliance and lively faceting contrast, with pleochroic tendencies that reveal deeper blue tones at certain angles and greener tones at others, adding dynamic color movement during wear. Clarity is graded eye clean, evaluated at eye level, and the excellent polish ensures crisp facet junctions and clean reflections. The sapphire has been heat treated, a standard and stable enhancement used to improve colour uniformity and to minimize minor inclusions without affecting the gemological integrity of the material.

From a craftsmanship perspective this gem reflects careful preforming and cutting decisions to retain weight while optimising optical performance, the cushion outline preserves a strong face up presence while the mixed brilliant scheme increases perceived brilliance relative to a pure step cut. The girdle and symmetry are executed to facilitate secure mountings in rings or pendants, and the depth of 4.72 mm is tuned to provide robust durability for daily wear. Presented by The Natural Sapphire Company, this sapphire makes a striking gift for someone special, its uncommon bluish green tone and substantial 4.78 carat mass combining visual impact with wearable proportions. For a memorable commission consider a setting that showcases the cushion silhouette and allows light to enter the pavilion, a solitaire or halo configuration will emphasise the stone s colour and movement, creating a personal jewellery piece that celebrates both the material excellence and the meticulous craftsmanship behind the gem.
