Is it possible?   Absolutely.   There's a lot we don't know about Earth's core.  There might be a 4th layer, quite small, made up of Platinum, Gold and other dense metals.     http://discovermagazine.com/2006/sep/innerfortknox

Cool! I guess it makes perfect sense for earth to have more then two or three cores/layers. Thanks

Earth's inner core has an inner core inside itself. Are there three inner cores?
