The Aegis | Trillion Multi Stone Engagement Ring

A symbol of strength, protection, and radiant purpose.

Bold, protective, and beautifully precise, The Aegis draws its name from the legendary shield of the gods, a symbol of guardianship and divine power. At its heart lies a brilliant centre diamond, flanked by sharp trillion-cut side stones that echo the angular elegance of a warrior’s crest.

This three-stone engagement ring is sculptural yet refined, honouring the past, present, and future with balance and brilliance. The triangular shoulders reflect clarity and courage, wrapping the centre in a radiant embrace that feels both modern and mythic.

Crafted for those who love fiercely, protect loyally, and shine with unmistakable purpose.

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Astella, we help you make the most of your budget by focusing on design, diamond quality, and craftsmanship rather than outdated spending rules.
