A double-sided heart-shaped bead, with a 2mm hole.
I photographed it next to a cm ruler, on a 5mm grid for you to better understand its size...
One side is "Chai", added with a thin blue glass rod (writing with molten glass is extremely hard, but feels amazing), the other is a Magen David, a bit stylized like a flower with pointy petals...
It is one bead of my heart-shaped israeli beads collection...
