Princess Maud of Fife's engagement ring
"Her engagement ring, by the way, has a most original setting. It consists of a large, square diamond with a row of emeralds around it, and with more diamonds at the two corners extending round the actual circlet. It was quite surprising that she didn't have rubies, as she is so fond of red. . . "The Sketch, 14 November 1923, p 10
"Lord Carnegie has now bought the wedding ring and his gifts to his bride and bridesmaids. The ring is a very slender one of gold in the latest "round" design, and will go very well with the engagement ring, which has a large diamond centred in emeralds."Dundee Courier, 09 November 1923, p 5
