5.09 Ct. Blue Sapphire from Madagascar

This transparent blue sapphire weighs 5.09 carats, and presents an elegant oval outline with dimensions of 10.52 by 8.37 by 6.20 mm, and a mixed brilliant cut that balances faceting for strong light performance. The stone displays an intense color intensity, and the excellent polish contributes to crisp facet junctions and lively return of light. Clarity is graded very slightly included, evaluated at eye level, which in practical terms means the stone is clean to the naked eye and any minor natural inclusions are not impactful on overall appearance or brilliance. The combination of substantial carat weight, generous face up dimensions, and superior polish creates a visual presence that is ideally suited to a statement piece, while the mixed brilliant cut enhances scintillation across the table and crown, making the sapphire read larger in hand than its carat weight alone might suggest.

The clarity and transparency of this sapphire are particularly notable when assessing suitability for a prominent single stone setting. Very slightly included gems of this grade retain exceptional light transmission, and this example shows clear passages of light across its pavilion and crown that amplify depth of color without appearing overly dark. The oval shape provides an elongated table that maximizes the visible surface, and at 10.52 by 8.37 mm the stone offers a commanding face up area that will occupy the eye in a solitaire ring, a pendant, or a bold cocktail design. Durability is inherent in corundum, and the clean polish and well executed mixed brilliant faceting reduce the need for overly protective settings that can obscure the girdle or crown, allowing designers to emphasize the sapphire itself in open metal settings that let the gem lead the composition.

Provenance and treatment status are central to the stone character, and this sapphire is from Madagascar and has no enhancement. The absence of heat or other treatments preserves the natural crystal structure and color distribution, a quality that many collectors and designers value when selecting a feature gem for a statement piece. The origin from Madagascar contributes to a distinct color character within the blue sapphire family, and the intense tone combined with the transparent clarity gives the gem a modern yet timeless appeal. At The Natural Sapphire Company we document these attributes with high resolution imagery and detailed measurements to ensure clients understand how size, clarity, cut, and origin combine to create a sapphire that is visually commanding and technically suited to prominent jewelry applications. This stone is appropriate for settings where the gem is the focal point, and its dimensions and clarity make it especially effective when set to maximize table exposure and light entry, ensuring a statement piece that is both visibly impressive and technically well considered.
