Sethi Couture "Modern Heritage" 18K White Gold Diamond Eternity Band
Distinctive and artfully designed, the Sethi Couture “Modern Heritage” eternity band blends contemporary geometry with timeless elegance. Handcrafted in radiant 18K white gold, this striking band features a repeating pattern of diamond trios, combining baguette and round stones for a bold yet balanced look.
Thirty white diamonds sparkle around the band—ten baguette-cut diamonds paired with twenty round brilliant-cut diamonds—creating a rhythmic pattern that catches light from every angle. Each diamond is bezel-set with delicate milgrain detailing around the round stones, enhancing both the craftsmanship and vintage-inspired charm.
Measuring 4.75mm wide, this eternity band makes a statement whether worn on its own, paired with an engagement ring, or stacked for a layered effect. With its weight of 1.50 total carats, it embodies both presence and elegance, making it an heirloom-worthy piece to treasure.
Springer’s Jewelers—New England’s trusted jeweler since 1870—proudly offers this exceptional Sethi Couture design in our Portland, ME, Bath, ME, and tax-free Portsmouth, NH locations.

1. Clean your jewelry regularly. We recommend using a soft-bristled, non-metallic brush, and a mild soap and warm water solution. Gently scrub the diamond, and make sure to get the prongs and setting where buildup is likely.
2. Rinse your jewelry and dry it completely before storing to avoid leaving residual water stains on the metal.
3. Store your jewelry somewhere safe and dry, like a fabric-lined jewelry box with separate compartments. Try not to let your pieces touch, as they could scratch.
