The Vow Engagement Rings
The Vow collection gathers light into a halo of protection.
It begins with the halo: a ring of diamonds encircling the centre stone, drawn into a defined contour that strengthens its silhouette. Designed by Creative Director Erica Bianchini in 2009, each diamond is set by hand to reinforce the symmetry of the circle and to carry a continuous field of light. Crafted in Canada from solid recycled gold or sustainable platinum, The Vow is set with ethical natural diamonds, lab-grown diamonds, or vivid coloured stones, chosen for brilliance and traceable provenance.
Yellow gold halo engagement rings extend the perimeter argument into the material itself. Where white metal creates contrast between band and stone, 18k solid yellow gold of recycled origin creates continuity: a single warm field from band to halo to centre, the light field deepened rather than divided. The Vow's tourmaline and morganite halo designs carry this furthest, stones whose warmth and the metal's warmth form one composition, the perimeter and what it holds reading as inseparable.
Within Ecksand's vertically integrated Montreal atelier, the halo is calibrated through 3D design and again by hand. Spacing, height, and angle are drawn to exact tolerances so the light moves cleanly around the stone and the structure holds. Each diamond is hand-set within the halo, the surface finished with a multi-stage polish that sharpens the line of the silhouette.
The Vow holds a range of ethical centre stones: round, oval, emerald, radiant, and beyond. Bearing depth and proportion are recalibrated for each, so the halo keeps its integrity while drawing the stone forward. You choose the colour, carat, and clarity; Ecksand's artisans engineer the architecture that carries it.
A perimeter shaped by hand, drawn close as a promise, for the woman who guards her own.
