In his book, "Beads of the World", Peter Francis, Jr. describes: "These Beads were made with a hand held mold that left a conical perforation (hole). They were then put on a stick and the facets ground (by hand). As a group, these (diamond/ saucer shape) beads were called "Vaseline" Beads by American collectors after the green color associated with the product Vaseline."
Vaseline beads were traded in Africa for many decades, and were made in the late 18th century.
These beads have now become quite rare
