Lab-Grown Diamond Engagement Ring

Light catches the elongated silhouette of a marquise diamond, its pointed ends drawing the eye along the graceful curve of the finger. This semi-set halo engagement ring invites you to select a 10 x 5 mm marquise stone, ready to be embraced by a delicate frame of shimmering accents.

Crafted in 10K white gold, the band offers a subtle coolness against the skin, polished to a soft gleam that complements the diamond’s fiery brilliance. The halo setting balances sparkle with wearability, designed low enough for daily comfort yet elevated enough to catch the light with every movement.

Each piece reflects a commitment to sustainability, featuring lab-grown diamonds that mirror the clarity and fire of mined stones without the environmental cost. This ring’s refined profile suits hands that appreciate elegance without excess bulk, and its shape naturally elongates the finger, enhancing a slender silhouette.

Whether worn alone or paired with a wedding band, the halo’s gentle curve and the marquise’s distinctive form create a harmonious stack. Resizing is handled in-studio with care, ensuring a seamless fit tailored to your hand.
