His jewelry source is Monty. Monty originally was Chris' nephew and they were at the Oberoi in Mumbai. Chris died and Monty split off from Chris' family, going on his own. My recommendation would be to go to Monty directly. He is primarily in Dubai now. I don't have his email or contact handy, but I'm pretty sure Timbo could PM it to you since he eats all the butter chicken before anyone gets a chance.

You won't be disappointed. He has access to stones not available in the US market.
