The specimen shows quite good transparency and the typical orientated rutile needles und the microscope. Totally natural and not like many others offered specimens which became heat treated. Burned trapiche rubies disclosing mostly a white pattern, here you can see natural irons staining which you won’t see in a burned piece!
