Baily's Beads

Baily's Beads occur just prior to 2nd and just after 3rd contact in a total solar eclipse. This string of pearls is caused by light from the sun's photosphere reaching us through low spots on the edge of the moon. The diamond ring effect is when only a single bright bead of light is visible. Although described by Francis Baily in 1836, the phenomenon was first reported by Isaac Newton in 1715 [Wikipedia].
