Lab-Grown Diamond Engagement Ring

Imagine the subtle elongation of a marquise diamond catching light with every turn of the hand—its tapered points lending a refined silhouette that feels both bold and elegant. This semi-set engagement ring foundation in 10K white gold offers a low-profile setting designed for everyday wear, balancing secure prongs with a sleek band that rests comfortably against the finger.

Crafted in Williamsburg, the band is polished to a smooth finish, ensuring a gentle feel beneath the hand while maintaining durability for daily life. The mounting’s design allows for a 5 x 3 mm marquise center stone to be chosen and set with precision, complemented by delicate accent stones that enhance its architectural shape without adding bulk.

Each piece reflects a commitment to ethical jewelry through the use of lab-grown diamonds, reducing environmental impact while preserving exceptional clarity and brilliance. The ring’s modest height and streamlined profile make it glove-friendly and ideal for stacking alongside wedding bands or personal favorites.

Should sizing adjustments be needed, our Brooklyn studio offers expert resizing to maintain the integrity of the setting and comfort fit. Lead times are transparent and tailored to your custom design process.
