I recommend Basra pearls as investment pieces. Basra pearls are pearls occurring naturally in the Persian Gulf.

According to GIA's pearl course, limited quantities of Basra pearls are still being harvested in the Persian Gulf, mostly golden, up to 8mm in size.

I am pleased to offer these rare natural pearls on my site. Each item comes with a certificate of authenticity.
