The elongated navette shape of marquise cut sapphires creates the illusion of greater size, appearing up to 15% larger than round stones of identical carat weight. This advantageous spread offers excellent value for buyers seeking maximum visual impact at a lower cost per gram, making these elegant gems particularly worthwhile investments for those prioritizing face-up appearance.
Blue and violet sapphires typically display exceptional brilliance in marquise cuts, as the faceting pattern enhances color saturation while minimizing the bow-tie effect. The most valuable marquise sapphires exhibit rich, even color from end to end, with GIA certified natural stones commanding premium prices for their rare combination of desirable color, clarity, and precise cutting.
When purchasing marquise sapphires, buyers should examine the stone from multiple angles to assess the bow-tie effect—a dark area across the center. The most valuable specimens display minimal bow-tie presence while maintaining excellent light performance. This balance requires precise cutting of the genuine gemstone, significantly impacting both its aesthetic quality and market worth.
