Lab-Grown Diamond Engagement Ring

Light catches the elongated silhouette of a marquise diamond, its pointed ends drawing the eye along the finger with subtle drama. This solitaire semi-set ring offers a refined foundation for a 9 x 4.5 mm marquise stone, designed to sit low and secure for everyday wear.

Crafted from 14K white gold, the mounting balances durability with a sleek profile, ensuring the band feels comfortable without excess bulk. The setting’s precision allows the diamond to take center stage while maintaining a secure hold, finished with meticulous hand polishing in our Williamsburg studio.

Each lab-grown diamond embodies clarity and brilliance without the environmental cost of mining, reflecting our commitment to ethical jewelry. The slender band suits those who favor understated elegance and pairs effortlessly with stacking rings or a wedding band.

Its low-profile design is glove-friendly and ideal for active lifestyles, offering both sophistication and practicality. Should you wish to customize the fit, resizing is available to ensure a perfect, comfortable wear.
