The style of White Heart beads was invented around the year 1480, whereby red glass was colored using actual gold. Naturally, because of its value, the gold had to be used sparingly by the bead makers. As such, they instead opted to use cheap color filler for the core of the bead with the red only forming the outer layer. During the years 1480 – 1830, bead makers began using green color to craft these beads. However, after 1830 both yellow and white were commonly used, along with a translucent red coat. After 1860, bead makers stopped using yellow altogether in making White Heart beads and exclusively opted for white color.
