I saw a necklace once that was kind of like the one shown but it was waaaay expensive so I did my own version. Good luck! :D

Create a "nest" out of some fairly flexible metal wire-- this can be very random just make sure that it is oval shaped and looks like you pressed your thumb into the front of it.

Next, put your chain through;
Find a length that is just right for you, cut your chain and loop it through the top of you "nest"
You can use a jump ring for this if you want, however it is not really necessary and looks better without it.
Now attach your jump rings and lobster clasp (I needed 2 jump rings to attach a clasp) to one end of you chain and the other jump ring to the opposite side.

Thirdly glue on your "eggs" (pearls) to the "nest" that you made using either a strong glue or a rubber cement in small amounts.
Leave to set over night and flaunt in the morning! ;p
