What are votive objects?

A votive is defined as, "offered or consecrated in fulfillment of a vow," by multiple dictionaries. The word comes from the late 16th century Latin. The original sense of the word was 'expressing a desire.'

I have seen them once in Greek Mythology and once again in Spanish(Mexican/Mexican-American) culture. The first was a wreath on a tree in Demeter's Grove. The second was named a God's Eye.

My question is not so much as the use or purpose of a votive object. It is more like, what could it be? What made an object a votive? Did one have to be made of something special? If so, what?
