Sunlight catches the elongated silhouette of a marquise diamond, its tapered points drawing the eye along a graceful arc. This 9 x 4.5 mm center stone is nestled in a 14K yellow gold band, where artisan hands have shaped and polished every curve to a warm, tactile finish.

The setting embraces the marquise with delicate accent stones, enhancing its signature brilliance without overpowering the diamond’s distinctive profile. A low-profile design ensures the ring sits comfortably for daily wear, while the smooth interior offers a subtle comfort fit that feels natural on the finger.

Crafted in our Williamsburg studio, this engagement ring reflects a commitment to ethical sourcing through its lab-grown diamond, offering clarity and sparkle with a lighter environmental footprint. The 14K yellow gold is carefully alloyed and finished to highlight its rich hue, marrying tradition with modern sustainability.

Ideal for those who appreciate a statement shape that elongates the hand, this ring pairs effortlessly with stackable bands or stands alone as a singular expression of refined taste. Its balanced proportions suit a variety of finger sizes, making it a versatile choice for everyday elegance.

Should you need a custom adjustment, resizing is handled with precision in-studio to maintain the ring’s integrity and comfort. Typical lead times reflect our dedication to handcrafted quality rather than mass production.
