Help identifying if natural or dyed GSSP

[KaoLovesPearls]

I'm considering making a purchase of GSSP and I was wondering if these were dyed or not. I'm not good at identifying GSSP as I am with Tahitians so I thought I'd ask the experts for help! They're all the same pair and the seller identified them as genuine and natural in color from the Maluku Islands. I know GSSP grows in the Philippines but am unaware of this area as well. Thank you!!!
