I just ran across this after reading about Passports With Purpose in the New York Times. For each $10 donation - which will be used to build a school in Cambodia - the donor can enter to win a prize donated by the sponsor of a travel blogger.
Scroll down near the bottom in the "other" prize category and you will find that one of the prizes offered is a Tahitian pearl from Kamoka farm. It comes courtesy of travel writer Celeste Brash and her sponsor/husband Josh.
More about this fundraising program and a photo of the winning Kamoka pearl from Celeste can be found here: http://coconutradio.blogspot.com/sea...hitian%20pearl
I'm pretty sure this will be the only time a Kamoka pearl can be had for a mere $10. Wouldn't it be great if a P-G-er that won it? But you'll have to beat me. Hurry, entries are accepted only through Dec. 21st.
