I came across the chart for this simple but pretty crochet hoop earring quite by accident on Pinterest at http://pinterest.com/flordecactus/crochet-earrings/
However, I was unable to locate the pattern chart at what was listed as being the originating site (crochet-plaisir-over-blog.com).
As you can see in the photos, I made my first pair of earrings without the beads indicated in the chart.
I tend to find it easier to work from written instructions rather than charts, so I transcribed the chart below.
CROCHET DANGLE EARRINGS WITH BEADS
Supplies: 1 pair of 3cm diameter latchback hoop earrings; size 3 cotton thread; size C (2.75mm) hook; 10 beads of your choice (5 for each earring), optional. (If not using beads, see alternate instructions below.)
String 5 beads onto cotton thread. Leaving a long tail, make a slipknot in the thread and place slipknot on the hook.
Row 1: Working around the earring hoop, sc 38. Turn.
Row 2: Sl 7; ch 6; sl in 5th sc from ch. Ch 6; dc in 5th sc from ch. Ch 6; dc in 5th sc from ch. Ch 6; sl in 5th sc from ch. Ch 6; sl in 5th sc from ch. Turn.
