Diamond ring. Set with an emerald-cut diamond weighing approximately 4.30 carats, this showstopping ring balances its substantial size with elegance, thanks to the geometric perfection of its diamond faceting. The emerald cut is so-called because it is most commonly associated with emeralds, where it is ideal for showcasing colour, the cut corners helping to avoid chipping. Used on diamonds, this cut rose to prominence in the opening decades of the 20^th century, where the clean, straight lines harmonised beautifully with the prevailing Art Deco aesthetic. This showstopping Vintage Engagement Ring channels this timeless aesthetic into a contemporary design – an excellent choice for an engagement ring, certain to stand the test of time.
