Hello Tammy
In my experience in jewelry making for particularly for men, since men really do not like wearing jewelry, best method or best thing you can do and use would be a stretchy elastic threads, and use any of the 3 different kinds of the tiger eye beads. The older they individual, the bigger the gemstone. you can use an 8mm red tiger-eye stones, for an older male, you can use 10mm stones. There are different kinds of tiger eye, from blue tiger eye also knows as hawks eye, to the original yellow gold tiger eye and of course the red tiger eye. In my opinion these stones are masculine and look great on a guy.
Try to stay away from using clasps <img src="/images/graemlins/wink.gif" alt="" />
PS: if you can find the RARE blue-gold mix of the tiger-eye in 8mm, these are absolutely beautiful.
