The original white heart trade bead is known as a Cornaline d' Aleppo or white heart bead. The first Cornaline d' Aleppo beads were green heart beads. The green heart bead was made by the millions beginning about 300 year back and more. The Venetians first attempt at making a white heart bead was in 1825. The bead produced was a pinkish white color. They were made in 1825 and continued to be made until 1850. In 1850 the Venetians found the right combination of ingreients for making the pure white heart trade bead. When we use the term 'white heart' we are talking about the inside layer of the trade bead. One will see red white hearts, green white hearts, blue white hearts, and more. Some, such as the bead with a yellow/orange colored outter layer and the inside white core are very unique and rare beads.
