The oil like looking stain is there to stay..the rest might be finger printsThere are actually 3 defects I can see in this photo - lighter parts on the edges of carnelian and that dark stain. I asked the SA about them, but he had no clue, only saying hopefully it is only lighting issue as only one photo was available.
I check the items super thoroughly these days after my experience with the MOP earrings. Very sad VCA passes such quality items at such a price tag.
