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
