The Throne of Hera | Round Diamond Engagement Ring with Emerald-Cut Side Stones
A round brilliant centre stone sits between two emerald-cut diamond shoulders in this three-stone design, pairing the round's even distribution of light with the emerald cut's flat, linear planes.
The contrast is deliberate: the round brilliant's sparkle reads as constant movement, while the emerald-cut side diamonds stay still and structural beside it, their crisp facets framing the centre rather than competing with it.
Together they give the ring a symmetrical, architectural profile from every angle, wider across the hand than a solitaire and built to hold its shape rather than shift with the light. The 1.51ct lab-grown centre diamond (G colour, VS1 clarity, ideal cut) is joined by an estimated 0.50ct of lab-grown diamond across the emerald-cut side stones, set in 18kt yellow gold.
It is the more restrained of the two Throne of Hera specifications on this shortlist, built for everyday presence rather than maximum scale.
