Lab-Grown Diamond Engagement Ring

Imagine the subtle elongation of your hand as a marquise diamond, measuring 9 by 4.5 millimeters, catches the light with its tapered brilliance. This solitaire semi-set rests on an 18K yellow gold band designed for everyday grace—low profile and secure, it slips comfortably beneath gloves and stacks with ease.

Each ring is crafted in our Williamsburg studio, where the band is meticulously shaped and polished to a smooth finish that balances durability with refined wearability. The semi-set allows you to select a lab-grown marquise diamond that meets your clarity and color preferences, ensuring a personalized centerpiece.

Our commitment to ethical jewelry is reflected in the use of sustainably sourced 18K yellow gold paired with a lab-grown diamond, offering clarity and sparkle without compromise.

The slender silhouette suits hands that appreciate architectural elegance and a confident yet understated statement. Its low profile setting minimizes snagging, making it ideal for daily wear and layering with other bands.

Should you need resizing, our Brooklyn studio provides expert adjustments to ensure a perfect fit without disrupting the ring’s balance.
