The price of this stone?

Hello I wonder if there is more than one type osstone in this collection . Some looks like Amber and other pieces like fire opal and again others like agate . what do you consider them to be . I have a similar collection and am intrigued by this group

Start with a hardness test, which will differentiate amber from other, harder stones like agate quickly. Then a simple “heft” test would help, as density of amber is also less than agate. Compare heft of this to a simple quartz pebble. If you have a $12 scale, do an SG. -royjohn

Some are carnelian agates
