French 18K yellow gold 1.5ct old mine cut diamond signet ring
A study in quiet drama, this striking French signet ring captures everything we adore with a bold presence and a sculptural simplicity. Sleek and undeniably chic, it showcases an old mine cut diamond in a square setting at the center (weight estimated at approximately 1.5ct, color I, clarity SI)
The oval diamond is flush set into the face of the ring, creating a beautifully seamless profile while allowing the stone to remain the undeniable focal point. An open-back setting lets light move freely beneath, enhancing the diamond’s brilliance.
Confident enough to stand entirely on its own, this piece makes an effortless statement worn solo, yet its clean lines make it wonderfully stackable, slipping easily into a layered ring story without losing an ounce of presence.
The ring is resizable, please contact us before passing your order.
