The features of Lady Diamond are typical of ballads.

First of all, we have no information about the composer and a huge number of famous ballads are anonymous too.

Also the layout of the text reminds the ballad form: it is organized into thirteen stanzas and the reader can note the presence of numerous quotation marks, which introduce direct speech. As a matter of fact, a ballad is a narrative form of poetry and it is about the interaction of different characters. In particular, Lady Diamond deals with a tragic love (typical theme of ballads) between a princess and a kitchen boy.

This ballad has no refrains but the reader can note the incremental repetition of a key word (f.e. a king a noble king a king in the 1^st stanza), a phrase (she loved him and she loved him aye in the 2^nd stanza) or a structure (for gone, for my bonnie Diamond, for the love in the 12^th stanza) in the same stanza; rhyme is very used too (greet/meet within/pin joy/boy). All these devices favored memorization and made the ballad pleasant to hear.
