Have you seen Aqua colour like this before?

[PaulS72088]

Hi,

I had a 100kg of “mine run” emerald delivered back in 2000 and have thinned it down over the years to a few bags of nicely coloured green opaque beryl and some nice emerald crystals (for want of a better description).

The stuff I have sorted out is good for cabbing but amongst it all I found this single piece of blue material, it is around 40mm x 20mm x 6mm thick and is a colour I have not seen before if it is Aqua.

The bag of material was sourced from brazil and I wondered if anyone else had seen aqua of this colour before or if it is likely/could be something else.

Cheers

Paul

I’m wondering if it might be a Paraiba (though that’s a tourmaline), but they are rare & originally sourced from Brazil. They are known for their “electric” blues, greens, & even purples.

Everyone seems to want the ones from Brazil instead of W. Africa, but they also want transparent stones despite the country of origin. Still, it might be worth getting it tested. Just a guess….

When I see that color my mind immediately goes to copper carbonate or silicate… first guess might be chrysoprase or chrysocolla.
