Is it a yellow sapphire? What could be its value?

[rarora]

Hi,
I have found a stone in my backyard & it looks a precious stone. It measures 2.5 inches by 1.5 inches. I am curious to know what kind it is and if it has any value. I would appreciate advice from experienced members.
Thanks

Very pretty. Could be any type of quartz. Do a hardness test to narrow your possibilities.

The colour zoning let's me think it's not corundum. Can't say what it is either, though.
Do a hardness test.

is it transparent? if so possibly agate. if not some sort of picture jasper? where was it found other than the backyard?

It's in the quartz agate family. Sapphire is very hard and generall comes in crystalized forms. Best US occurences are in North Carolina and Montana.

Looks like tumbled cullet glass

Glass would explain the colour zoning.
