Éternelle Emerald Cut Lab Grown Diamond Half Eternity Ring
The Éternelle Emerald Cut Lab Grown Diamond Half Eternity Ring by Sphere Diamond is a refined interpretation of the classic diamond eternity band. A continuous row of Emerald Cut lab grown diamonds extends across the upper half of the ring, creating a sophisticated rhythm of clean lines, step-cut facets and understated brilliance.
Designed for those who appreciate modern elegance, the elongated rectangular diamonds sit side by side across the band to create a sleek and architectural silhouette. The result is an elegant Lab Grown Diamond Eternity Ring that can be worn as a wedding band, anniversary ring, stacking ring or statement diamond band.
Emerald Cut Lab Grown Diamonds
Emerald Cut diamonds are distinguished by their rectangular shape and elegant step-cut facets. Unlike brilliant-cut diamonds, their beauty comes from crisp geometry, broad flashes of light and a sophisticated hall-of-mirrors appearance.
Arranging multiple Emerald Cut diamonds across the band creates a clean, structured look that makes Éternelle particularly suited to modern and minimalist jewelry styles.
Half Eternity Design
The diamond setting extends across the upper portion of the ring while the lower band remains smooth. This half eternity construction combines the visual impact of an Emerald Cut diamond band with a refined profile designed for comfortable everyday wear.
Perfect as a Wedding, Anniversary or Stacking Ring
Éternelle can be worn independently as an elegant diamond band or paired with an engagement ring to create a distinctive bridal stack. Its geometric Emerald Cut design also makes it a sophisticated choice for wedding anniversaries, milestone celebrations and everyday fine jewelry.
