Roll'd into light, and turning on its rims
Fled like a glittering rivulet to the tarn:
And down the shingly scaur he plunged, and caught,
And set it on his head, and in his heart
Heard murmurs, 'Lo, thou likewise shalt be King.'"


The diamonds reappear in the scene of Guinevere's jealousy:-


"All in an oriel on the summer side,
Vine-clad, of Arthur's palace toward the stream,
They met, and Lancelot kneeling utter'd, 'Queen,
Lady, my liege, in whom I have my joy,
Take, what I had not won except for you,
These jewels, and make me happy, making them
An armlet for the roundest arm on earth,
Or necklace for a neck to which the swan's
Is tawnier than her cygnet's: these are words:
Your beauty is your beauty, and I sin
In speaking, yet O grant my worship of it
Words, as we grant grief tears. Such sin in words,
Perchance, we both can pardon: but, my Queen,
I hear of rumours flying thro' your court.
Our bond, as not the bond of man and wife,
Should have in it an absoluter trust
To make up that defect: let rumours be:
When did not rumours fly? these, as I trust
That you trust me in your own nobleness,
I may not well believe that you believe.'
