It boasts a transformative centerpiece crafted as a convertible necklace-brooch of unparalleled artistry. At its heart lies a resplendent round-shape natural Ceylon sapphire, a dazzling gem of remarkable rarity, weighing a remarkable 23.01 carats. The centerpiece is an exquisite focal point, a dazzling spectacle adorned with a stylized floral cluster delicately adorned with round brilliant-cut and marquise brilliant-cut diamonds, further accentuated by smaller oval-shape sapphires.
