Looking for that lovely Windex blue color. Please list any vendors whom you know that sell them.
Unfortunately, it will be difficult to find a paraiba that hasn’t been clarity enhanced in some way. At least opticon is one of the more stable fillers,and definitely no dyes. You should therefore never put them in ultrasonic cleaners, or use steam cleaners on them. The jeweler should be made aware of this as well.I second paraiba International a lot of pariaba these days have been oil filled they also fill them with things like Opticon and most of the people selling them don't realise it, or that has been my experience with them. There is a huge gem seller that goes to Gem shows in Hong Kong and through out Asia that sells treated paraiba that claims they are oiled only.
You want heat only, untreated and NO oil or fillers or dyes of any kind.

I think they clarity enhance stones from both regions. Heat is always assumed. There are some Brazilian stones that were not heated in the early days of the discovery, but they are rarer than hen’s teeth. Even so, it’s almost impossible to determine non heated stones. Clarity enhancement is a whole different ball of wax.You can find heat only pariaba from Mozambique, the Brazilian stuff ie the real stuff from Paraiba well that's a whole other story.

Doug Menadue, in Sydney had a Brazilian one (old material) that was untreated lovely colour but a huge window several years ago that I looked at and sent back I still to this day regret not keeping that stone It sold like 5 minutes after I sent it back.
