White Opals

[President Trump]

Hi All,
These have been sitting in my draw for 35 years. Anyone know the value of stones like this or best place to get an accurate value. Thank you for your thoughts.

White Opal isn't worth much
Has some value but not much ,if it has flashes of red it has more value
Hard to tell by the pics
Can help you if your in Melbourne
