Whilst I endeavour to photograph earrings next to an ear so you can see the length, my model is only here occasionall, so some earrings may not be photographed this way and I realise that just seeing the length may not always give a good indication!
Please use this photo to get a better gauge on the length of the earring when it is being worn, by looking at where the length of the earring comes to on the tape measure.
Hope this helps!
