This is a rare indigo-blue sapphire. It is fully saturated and has beautiful sparkle in a cushion cut. The size is an impressive 5.88 carats, mined in Ratnapurara, Sri Lanka.
We designed a setting that provides the proper platform for this beautiful gemstone including a halo of large, colorless baguette diamonds with marquise diamonds at the corners, all in 18K yellow gold.
