Lab-Grown Diamond Engagement Ring

Sunlight catches the elongated silhouette of a marquise diamond, its tapered points drawing the eye along the hand’s natural lines. This semi-set halo ring foundation in warm 14K rose gold offers an artisan-crafted canvas for a 7 x 3.5 mm marquise center stone, ready to be chosen and set with care.

Each band is shaped and polished in our Williamsburg studio, where the soft blush of rose gold is hand-finished to a smooth, comfortable fit. The halo setting is designed to enhance the marquise’s dramatic profile while maintaining a low profile that slips easily beneath gloves or daily wear.

Our commitment to ethical jewelry is reflected in the option for a lab-grown diamond, combining clarity and brilliance with a mindful footprint.

This ring suits those who appreciate architectural elegance paired with subtle warmth—its slender band and halo detail complement slender fingers or stack beautifully with other bands for a personalized look.

Resizing is available to ensure a precise fit, and our team is happy to guide you through the selection and setting process with thoughtful timing.
