another paraiba thread

[Barrett]

Sent a small color suite off to be tested by a friend..these all came from same person who got them from same miner who got them from batalha mine/pegmatite in paraiba brazil..goes to show you never know unless you get a paraiba tested for copper..
first batch are the turquoise..these are copper bearing

 

[Barrett]

next is the greens..nbot one showed copper in the spectra

 

[Barrett]

next is the blue-green..only one showed copper in this batch..I was told it was also the brightest..i have yet to get vparcel back so will see

 

[Barrett]

next is the blues..all of these showed copper in them

 

[Barrett]

next is the purples..all of these showed copper in them also

 

[Barrett]

okay..so the turquoise, blues, and purples all showed copper..only one of the blue-greens shows copper..all the greens and the reat of the blues greens did not..all of you that have paraiba and don't have a gem/lab report then i woud be wary..like I said..i had to identical crystals tested..one was 6ct and one was 3cts. the 6 ct. facetgrade one tested positive..the 3ct one did not..side by side.they looked almost identical down a/b and c axis..both came from same person from same miner from batalha mine..you never know..so i have come to realize that even though my stones were had direct from brazil from a well respected dealer who in know way would ever try to pass off bad stones it's just a simple fact that no one can tell by looking at a stone if it's cuprian or not nor will I take anyones word anymore without a spectra..with having so many stones tested and having many not show copper..even ones I could have sworn had to be cuprian

Thanks for the heads up Amguy. As I always say, don''t pay extra for the paraiba name unless you have a reputable lab report that indicates the presence of copper AND it is a saturated glowy stone.

here is the spectra for the 5 different colors..as noted the turquoise and purples had identical lines...
