Grand Shared-Prong Round Diamond Eternity Band

Four carats of round brilliants circling the finger, and not a break in the light. This is the grandest of the shared-prong bands, each 4.1 mm stone a broad flash on its own and a wall of fire together.

Offered in lab-grown diamonds, it puts nearly four carats of real diamond within reach at a fraction of the natural cost. Shared prongs hold the stones edge to edge so the ring reads as one continuous run of light, in 14K or 18K gold or platinum. Carat total lands near 3 3/4 to 4 and ticks up on larger sizes.

Save it for the anniversary that deserves a headline, or wear it simply because a hand should sparkle. It stands alone with authority or crowns an engagement ring.

Priced from $2,889 complete. The price updates with the metal, finger size and diamond type you choose, and it is the full price of the finished band. Need a size or metal you do not see, or a half-eternity version of this design? Ask our concierge and we will quote it plainly.
