These earrings are comfortable and a good size. The back seems to fit securely. The earrings arrived intact and were delivered promptly considering my area was impacted by Hurricane Sandy. Only thing is the malachite pattern on these is not the most attractive - not the prominent striping - the front of the earring just looks darker than the back. I know these earrings are made from small pieces of malachite but the pattern in the pair I got could have been prettier. I guess it's just the luck of the draw.
