An extraordinary vintage tanzanite and diamond cocktail ring crafted in 14 karat yellow gold.

At the center sits a remarkable oval-cut tanzanite weighing approximately 21.19 carats, displaying vivid deep blue hues with flashes of violet depending on the light. The impressive scale and saturated color make this gemstone the undeniable focal point of the piece.

The center stone is surrounded by a substantial halo of round brilliant-cut diamonds totaling approximately 2.39 carats, arranged in a full, sculptural cluster that enhances both brilliance and presence.

The setting features bold gold prongs and dimensional detailing, giving the ring a rich, luxurious feel while securely framing the gemstone. The combination of strong color contrast, significant carat weight, and classic halo design creates a striking and timeless statement.
