These striking, deep red Venetian white heart beads came to us via the Ivory Coast, Africa. These are the real ones, the old ones. They fall under the designation of African trade beads. White heart beads, sometimes called "Cornaline D’aleppo" were made in Venice in the 19th century and were extensively traded throughout Africa. "Cornaline D’aleppo" stuck as a title as so many were traded through Aleppo through the 19th century en route to their distrubution throughout the continent of Africa. They are called white hearts because they all have a core of white glass, overwhich a jacket of another color is applied. These have a deep, brilliant scarlet red over their white hearts. photo . The color is deeper than the photo. They measure about 6mm in diameter, but there is some variation from bead to bead due to the process by which they are made. They start as a big bubble and then gets pulled out into a long tube which then gets cut into beads. They are $3 for twenty beads.
