And while every ring is different, all that matters is that the person popping the question manages to pick one their partner likes - right?
Well... People were disgusted when they saw the ring one boyfriend used to ask his girlfriend to be his bride - because it was made from his own hair.
The excited woman shared a snap of her hand wearing the 'ring', showing hundreds of strands of hair looped around her finger.
She wrote: "My boyfie is now my fiancé!
"He proposed with a ring made from a lock of his OWN HAIR.
"This is a placeholder, until my more intricately woven band is done."
A screenshot of her message was posted on the Facebook group That's It, I'm Ring Shaming, and has unsurprisingly attracted a lot of comments, reports the Sun .
One wrote: "No matter how much I love the dude I don't think I'd ever in a million years wear his hair on my finger."
Another commented: "Did she pull his hair from the drain and just wrap it around her finger? Does he even know they are engaged?"
Others questioned which part of his body the hair had come from.
