The slightly longer crystal is 16 mm (2/3 of an inch) in length, & is hung from a sterling silver hook. I can substitute surgical steel ear hooks if you have metal allergies. These particular stones have less indigo blue than some other ones I have sold, & a few small greyish patches of raw crystal visible on the larger stone near the holes - please check all of the photos carefully to see the many angles.
If you want smaller titanium crystal earrings, I have a pair here:
