That is the company that I was referring to.
The colors seem typical to me. I see nothing on the Website that one would not see in French Polynesia. The pearls with the golden tones are a bit more rare, however. The pearls are from Pinctada margaritifera, or Tahitian pearls (sorry CIBJO).
There is always going to be some degree of "fluff" in every island community's pearl marketing. You have to take everything with a grain of salt, remembering that every producer is very proud, and militant about their own production. There is nothing wrong with that.
It looks as though Justin Hunter is a local producer, and sells locally as well. This is likely why the pearls are not very well known around the world.
If you are going there on your honeymoon, then buy a piece! Find one for same reason people buy Tahitians when vacationing in French Polynesia - the intrinsic value. Sure, you are not going to get a great deal (Tahiti's prices are 4-5 times what you can find elsewhere for the same pearls, from French Polynesia). But you will be buying something you will never be able to replace; a pearl or strand of pearls purchased in Fiji on your honeymoon!
