Collection: Engagement Rings by Ethonica

Discover our engagement ring collection, where certified natural diamonds are set in gold and platinum to mark the start of a lifetime together. Each ring begins with a GIA or equivalent certified stone, chosen for its cut, rarity, and individuality — because no two natural diamonds are ever truly alike, and neither is your story. From classic round and oval brilliants to elongated cuts like marquise and emerald, our settings are designed for both everyday security and timeless sparkle, with prong and bezel options to suit how she actually lives. Every ring is handcrafted by us in the NYC Diamond District, backed by decades of diamond expertise, and available to view and try in person by private appointment. This is a ring meant to be worn, cherished, and one day passed down.
