Hmmmm…$250 per carat is pretty cheap Paraiba to start with. It may
well be material from the new discoveries in Africa. Or it may not
even be tourmaline at all, much less Paraiba.
I just did a search for the keyword “Paraiba” on the jewelry
television web site. The only stones that they claimed were actually
tourmaline were at the bottom of the page. The rest were things like
"paraiba colored apatite," or “paraiba ice, a simulant,” or some such
nonsense. Further, the 6X4 oval they claim actually IS tourmaline is
an auction piece that could go up well over its current price of $249
as people bid on it.
The gemological community recently agreed to call all copper-bearing
tourmalines “Paraiba.” Of course, since there is no more material
available from Paraiba itself, it’s a somewhat misleading practice to
begin with. But with jewelry television advertising junk like
"paraiba ice, a simulant," it gets very confusing for the layperson.
I strongly suggest you do business with a reputable dealer or cutter
you can trust, and pay the real price for the real item.
