Lab-Grown Diamond Engagement Ring

Morning light catches the gentle curve of an oval diamond, its elongated silhouette casting a subtle glow across your hand. This semi-set halo ring invites you to select a 9 x 7 mm oval center stone, known for its graceful elongation that visually lengthens the finger with soft, vintage allure.

Crafted from 18K white gold, the mounting features a delicate halo setting that amplifies brilliance while maintaining a refined profile. Each prong and pavé detail is hand-finished in our Williamsburg studio, ensuring a smooth comfort fit that sits low enough for everyday wear without sacrificing sparkle.

Our commitment to ethical jewelry shines through the exclusive use of lab-grown diamonds, offering clarity and sustainability in equal measure.

Designed for those who appreciate artisan craftsmanship and subtle sophistication, this ring pairs beautifully with stackable bands or stands alone as a statement of quiet elegance. Its low-profile setting is glove-friendly and ideal for active lifestyles.

Should you need resizing or wish to explore center stone options, our Brooklyn studio provides personalized guidance with typical lead times tailored to your design.
