Tourmaline

I have worked with Dominican amber and Larimar, but then became interested in other gems. Accidently, I saw at an auction a tourmaline. I was fascinated ,and luckily I won. And now I have won 2 pieces.
I began to find answers for what it was I have bought.
And what a jungle. There were high prices and others at very low prices. I found two similar ones, with $ 1000 / ct higher in price than the other.
So I got very confused.

Both of my tourmalines have an IGI certificate. IGI writes that those type of tourmaline are referred as Paraíba Tourmaline,
It does not say which country they come from.![167dc44d-566d-46d3-b6d2-5c4455206bf0|587x500]
The certificate says not so much about the quality.
And then they are encapsulated.

I’ve read that tourmaline is categorized by the 4 C. So if I want to find out what the rating is on those 2 pieces, do I then have to break the packaging and then send it to a new gemmologist or can it be evaluated based on the certificate and package and maybe just from the picture?

I hope someone can answer my question and possibly make a cautious offer of what value my tourmaline has :slight_smile:


any copper bearing tourmaline will be referred to as Paraiba. It can come from Mozambique or Afghanistan or Brazil. The Brazil one is the expensive one. looks like windex. And value as you can guess is based on color mostly. clarity second

IGI is garbage - pariaba comes from brazil - somebody stated that some tourmaline from Mozambique & Nigeria are to be considered pariaba. real pariaba is very expensive any thing over a carat is worth between 2k - 15k depending on quality & a natural unheated stone. Do your homework - you may have a stone worth a lot of money. good luck

Paraiba tourmaline, only comes from Brazil. Other tourmalines with the vivid bluish-green tourmalines, are noted “copper-bearing.” You can get it appraised at GIA, as I have done in the past, when I thought that I might have purchased a synthetic Alexandrite, instead of a genuine Alexandrite. Lucky for me, GIA graded the stone and it was authentic.

Note too that you’ll sometimes see stones being sold as “paraiba color” tourmaline. Pretty sure these are not Paraiba tourmalines either.

I really love tourmaline as well. I love the it for the vast array of colors it comes in, and for its dramatic look when cut.

My first prong setting, in fact, was a mint green tourmaline:

I remember reading in an article somewhere, possibly on this site, that some international standards body had gotten together and decided that any copper-bearing tourmaline counted as paraiba. Obviously the people who live in South America, especially Brazil, where Paraiba (sorry, I don’t know how accent marks work on this device) is actually located were pretty upset by this. As it seems to them to be the same issue as people selling "champagne"or “burgundy” that did not come from those places. Which the EU eventually put an end to.

Regardless I assume most labs in the northern hemisphere will regard any copper bearing tourmaline as paraiba, but South American Labs might not, and you will probably find a lot of contention over this for quite a while.
