Helios' Knot | Solitaire Engagement Ring

Bound by love. Strength in unity.

Hera’s Knot is a tribute to enduring connection, a sculptural expression of strength, devotion, and balance. Inspired by the symbolic rope motif, its twisted band forms a visible emblem of unity, where two strands become one, stronger together than they are apart.

At the centre, a brilliant natural diamond solitaire is cradled by curves of polished metal, spiralling with intention. Available in a wide range of shapes, including round, cushion, asscher, emerald, marquise, princess, radiant, and oval, the design honours the beauty found in intertwined lives and shared purpose.

Crafted in your choice of 18k white, yellow, or rose gold, Hera’s Knot is more than elegant, it’s elemental.

A bond that can’t be undone.

At Astella, we help you make the most of your budget by focusing on design, diamond quality, and craftsmanship rather than outdated spending rules.
