Lab-Grown Diamond Engagement Ring

Sunlight catches the elongated points of a marquise diamond, casting a slender, confident silhouette across the hand. This three-stone semi-set ring features a 12 x 6 mm marquise center, poised between two smaller stones that emphasize its architectural grace.

Crafted from warm 10K yellow gold, the band is polished to a smooth finish that feels substantial yet comfortable for daily wear. The low-profile setting keeps the stones secure while maintaining a sleek, modern-minimal aesthetic that balances clarity and structure without excess.

Each diamond is lab-grown, offering exceptional clarity and brilliance with a mindful approach to sustainability. This ethical jewelry choice reflects a commitment to responsible craftsmanship without compromise.

The elongated marquise shape naturally elongates the finger, making it ideal for those who appreciate bold geometry paired with refined understatement. Its semi-set state invites you to select a center stone that resonates personally, while the three-stone design adds symbolic depth and visual balance.

Resizing is available to ensure a precise fit, and the ring’s streamlined profile pairs effortlessly with stacking bands or a wedding band.
