Solitaire, Marquise Cut Lab Diamond, Hidden Halo Setting
An elongated marquise silhouette elevated by architectural precision and refined brilliance.
This design features a 2.00ct marquise cut lab-grown diamond secured in a sculptural setting with a hidden halo. The elevated shoulders draw the eye upward toward the centre stone, enhancing its length and presence while allowing light to enter from every angle. A concealed halo of round lab diamond beneath the centre stone introduces subtle brilliance from every profile, while a three-quarter pavé band of round lab diamond accents carries measured sparkle along the shank without detracting from the marquise's elegant form.
The centre stone is graded D colour, VVS1 clarity and Excellent cut, and its IGI report travels with the ring.
Part of the Insignia Collection, this ring is designed with permanence in mind. Each piece is made to order and meticulously finished, intended to endure well beyond the moment it marks.
