Steve,
I like that pendant design very much and your brooch at the start of this thread is beautiful in its colours and the warm tone of the gold - a pity these pearls + gold get soo easily very expensive....
Pricing is definitely an issue. Paua pricing at origin is calculated on the limited (albeit sustainable) source, and the spectacular (and natural) nature of the pearls themselves. Currently, wholesalers outside of NZ would not be able to offer freeforms much under $400 per carat, and the larger conicals, teeth, etc around $600. For the pearl in the pendant in my prior post, this looks to have a weight somewhere around 30 carats, so actually that's US$18,000, not $15,000 as in my post. That does not include the gold, diamond, one-off uniqueness, etc etc. Again, that's
wholesale.
Other abalone offerings, notably the red and green
Halioti as seen at Pearl Paradise and Pacific Pearls, are far less expensive. But there is certainly a color difference, in addition to general lack of similar availability of the smaller and more versatile gem-quality freeforms in the 0,5 to 5 carat range.
At least it's fairly unanimous that paua and the resulting jewelry are capable of unsurpassed beauty.
