This piece is just a momento. It's a decoration and doesn't really have any actual value. It's a sort "thank you for visiting our auction" gift for the participants. The pearl is a keshi, not a natural.
There are no freshwater pearl farms in the Philippines. The freshwater pearls you see in Greenhills have all come from China. All the stories about the farms in Mindanao you heard from the vendors are false. There are no pearl farms there.
This looks like it was used at one of ASBUMI organized auctions. This is the old cultured pearl organization of Indonesia. It's difficult to make out the piece, but it looks like it might be a keshi pearl. It wouldn't have much of any value. This looks like a paper weight or a decoration.
It is a South Sea pearl strand, so if the price is unreasonably low, it's a good opportunity. The clasp is a popular high-end for silver, but it isn't knotted yet so it the clasp hasn't been chosen.
An old friend of mine just reached out to me last month and asked if this was real. The way it's presented, it's not obvious satire.
There are several similar videos on YouTube.
