What need does love have for a ring?

Why does a vow need to be placed on the heart of a woman or a man who says they love each other.
Does a ring need to weigh down the words in representation of the emotion that we seek from another?
Why is it they need to entrap the love they say is strong enough to last forever, till an end comes to their lover?

If this feeling is so strong why must it be locked away in a diamond cage?
if it conquers all then why make it slave to a few words and a shiny hole to place on a finger.
My understanding of my own feelings may be only knee deep but I find the concept to of a ceremony to celebrate a love that has doomed many to be a fools game as it's carried above the head of those who are drowning in tradition.
