Lab-Grown Diamond Engagement Ring

When light catches the elongated silhouette of a marquise diamond, it creates a striking interplay of brilliance and shadow, evoking a quiet drama on the hand. This semi-set halo engagement ring in platinum offers a refined foundation for a 10 x 5 mm marquise center, designed to showcase the stone’s tapered elegance while maintaining a low profile for everyday comfort.

Crafted in solid platinum, the mounting features a delicate halo setting that enhances the diamond’s length without adding bulk, ensuring the ring sits close to the finger. The smooth, comfort-fit band balances durability with subtlety, making it suitable for daily wear and easy layering with other bands.

Each piece is meticulously finished and inspected in our Williamsburg studio, where precision meets thoughtful design. The use of a lab-grown diamond aligns with a commitment to ethical jewelry, offering clarity and sparkle with a reduced environmental footprint.

This style suits those who appreciate architectural grace and a sleek silhouette, especially flattering on slender fingers or anyone seeking a ring that feels as natural as it looks striking. Its low profile also makes it glove-friendly and practical for active lifestyles.

Should you need adjustments, resizing is available to ensure a perfect fit without compromising the ring’s integrity. Typical lead times reflect our handcrafted approach, allowing for personalized attention to every detail.
