This is what I just saw in an unheated sapphire I just examined. There was this sticky dark blue dyed appearance in just a part of the healed fracture and yes the fracture did reach the surface.
The same customer had a very light toned unheated pink sapphire. Again apparent healed fracture reaching the surface with a sticky dark pink finger print formation in a small part of total whitish fingerprint.
Here are two questions.
Are all fingerprint inclusions whitish?
Were these sapphires dyed? They were not cobalt treated or glass filled - no bubbles.
Thank you very much for your input. Happy holidays!
