A stone with this combination of features looks best in four-prong settings that protect the pointed corners, channel settings, and cathedral settings. At 3 carats, the stone has significant presence, so a simpler setting lets the diamond take center stage. The blue hue is extremely rare and highly prized, adding collectible appeal. The pointed corners can be vulnerable to chipping, so protective prong settings are recommended.
