Are these real Tahitian pearls? (14k white gold clasp)

[viktorrab]

The clasp, ring, and studs are all 14k white gold. I am new to this community, and am trying to learn. Please let me know what you think!

 

[Pearl Dreams]

They appear to be dyed freshwater pearls from China.

The colors are off compared to Tahitian pearls.

 

[A Breaker]

The shape is wrong too.

Not Tahitian!
