Some are aglow with the bloom that cleaves
To the limpid glory of new born leaves. (lines 11-12)
In the above lines the poet compares the shiny green bangles to the transparent beauty (limpid glory) of the light green, new born leaves.
The new born leaves shine with the bloom (a delicate powdery surface deposit) that cleaves (adheres or sticks) to those leaves. The green bangles are shining the same way, as the poet describes them. These bangles symbolize the tender nature of a maiden girl.
