5.02 Ct. Bluish Green Sapphire from Madagascar

This is a transparent, 5.02 carat cushion shape bluish green sapphire, precisely measured at 10.37 x 8.44 x 6.03 mm, cut with a mixed brilliant pavilion to balance broad table brilliance with lively facet scintillation. Color is described as intense, and the stone exhibits attractive bluish green tones that shift subtly with viewing angle, indicative of sapphire pleochroism and the complex trace element chemistry typical of Madagascar sapphires. Clarity is graded as very slightly included at eye level, meaning inclusions are minimal and do not materially interfere with light performance or durability when set, and the excellent polish ensures sharp facet definition and optimal light return. Importantly, this sapphire is natural with no enhancement, a characteristic that significantly enhances its desirability and long term value for informed buyers, and its Madagascar origin situates it among a respected group of gems known for rich, saturated colors and good crystal quality.

For custom jewelry, this sapphire is exceptionally well suited due to its weight and cushion proportions, which create a commanding presence without overwhelming typical ring or pendant designs. At just over five carats and measuring slightly over ten by eight millimeters, the stone works beautifully as a centerpiece for an engagement ring, a solitaire pendant, or a cocktail ring where the cushion shape provides a classic, elegant silhouette that flatters both prong and bezel settings. The mixed brilliant cut provides a combination of depth and surface sparkle, so we recommend settings that allow light to enter the pavilion, such as a four or six prong or an open gallery, to maximize brilliance. Metal choices can subtly influence perceived color, with platinum or 18k white gold emphasizing the sapphire s blue tones, while 18k yellow or rose gold can warm the green character for a more vintage feel. Because the sapphire is untreated, its natural color distribution and clarity patterns should be considered during setting orientation to present the most desirable hue face up, and our design team at The Natural Sapphire Company can provide CAD visualizations and mounting suggestions to optimize color, balance, and wearability.
