The 18K Gold Diamond Engagement Ring is the classic done right. A natural round diamond sits in a prong setting elevated above a slender 18K gold band, with diamond accents running along the shoulders that add sparkle without competing with the center stone. Light at just over 2 grams, it wears with the ease of an everyday ring and the presence of a fine jewelry piece. Round brilliant, prong set, 18K gold — the combination that has defined the engagement ring for a reason. Available in yellow, white, or rose gold.
