We rarely have natural gold nuggets for sale from Costa Rica. It's been quite some time since we have had any gold nuggets for sale from this location. They are difficult to come by in any size or quantity, as much of the gold found by gold prospectors in Costa Rica is fine gold. Since we only sell clean jewelry/investment grade gold nuggets, that makes the search for suitable nuggets even more difficult. Nuggets from this prospector in Costa Rica have been assayed at 94% to 97% pure gold, on par with our high quality Australian nuggets. We just got in these two gorgeous clean jewelry/investment grade gold nuggets and I don't know when we will be able to get any more, so grab one while you have the chance.
