Callire, out of curiosity, are you a jeweler? Forgive my ignorance, but what is the PG? The Pearl Guide website?
For those looking at South Sea and Tahitian pearls, Japster's pearls are amazing. And she does offer a discount for TPFers, I think the code is in her signature so just look her up. I understand that everyone has different price points, but if you're looking for high-quality hand-crafted work and higher-end South Seas, a lot of us go to Elana. Paspaley is the best known world-producer of high-end South Seas as I'm sure you must know Callire. The Pearl Guide has a GIA Alumni tour of Paspaley here:

Japster is quite the expert on these pearls so I'll let her jump in to elaborate. Here's a not so great picture of the Paspaley South Sea baroque strand from Elana I received for Mother's Day. Taken in very dim natural lighting on a grey day on my MacBook in the worst of lighting conditions and they are quite luminous. I'm expecting delivery of some 16mm silver grey drops later this week and will post better pictures along with my South Sea baroque strand and studs.
