Ralph Waldo Emerson - Rubies lyrics

They brought me rubies from the mine, And held them to the sun; I said, they are drops of frozen wine From Eden's vats that run. I looked again,—I thought them hearts Of friends to friends unknown; Tides that should warm each neighboring life Are locked in sparkling stone. But fire to thaw that ruddy snow, To break enchanted ice, And give love's scarlet tides to flow,— When shall that sun arise?
