I took another picture on the same envelope with a penny. It appears that any dark smudge on the paper, penny, or pearl appear blue when I don't use the flash on my phone. So hopefully to clear this up I took another picture with and without flash. I'm not trying to pull wool over anyone's...
No photo shopping here guys, I just placed the penny on an envelope to show size of it. I don't know anything about pearls, googled it and this forum came up. The picture was taken from my phone in my truck. I'll take another photo of it in my hand. Thanks for all the replies so far.
