Lab-Grown Diamond Engagement Ring

Imagine the subtle drama of a marquise diamond, its elongated silhouette catching light like a shard of morning sun. This semi-set halo engagement ring in platinum awaits your choice of a 10 x 5 mm center stone, designed to frame the gem with delicate artisan precision.

Handcrafted in our Williamsburg studio, the platinum band is polished to a satin finish that balances durability with a refined glow. The halo setting, meticulously crafted to hug the center stone, enhances brilliance while maintaining a low profile for everyday wear. Each prong is shaped and inspected by hand, ensuring a secure yet elegant hold that complements the marquise’s tapered points.

Our commitment to lab-grown diamonds means your ring begins with a gem of exceptional clarity and ethical provenance, reflecting a modern approach to fine jewelry.

The slender platinum band offers a comfortable fit, ideal for those who appreciate a ring that feels as natural as it looks. Its low-profile halo design pairs beautifully with stacking bands or stands alone as a statement of quiet sophistication.

Should you need resizing or prefer a custom finish, our Brooklyn studio welcomes your questions with a pressure-free approach and expert guidance.
