1.84 Round Brilliant Cut Diamond Engagement Ring in 14k Yellow Gold.  This modern engagement ring features a 1.84 carat round brilliant cut diamond set in 14 karat yellow gold. We affectionately call this design the little black dress, because it looks amazing on everybody. The two small accent diamonds break up the silhouette just enough to make it interesting, without taking much of the gaze away from the gorgeous center stone. The polished 14 karat yellow gold gives a bright contrast with the white diamonds to complete this amazing ring.
