Hi all, so I decided to return it only because I'm thinking of doing a custom project with the seller. This is the stone I got - 0.58 ct, untreated / no oil.
If anyone wants this original 3 stones one - let me know and I'll post the seller name - I'm not affiliated. It went to gia in Carlsbad who confirmed that it is earth mined diamond, 0.37 ct, VVS and G and the emeralds are untreated, no oil, 0.54 tcw. It was around $1300. I wanted to keep it because I love the diamond, but can't do both.
