LD |1445959616|3942565 said:I thought you might want to see the reasons why I don't think it's a Tourmaline:
(a) the size
(b) the clarity
(c) the colour speaks more of Topaz than Tourmaline
(d) the setting - if this were a gem of note, typically, the setting would be more elaborate.

If it is Tourmaline then, although a very nice stone, it doesn't exhibit the qualities of a "Paraiba" as it doesn't have a neon glow. It may well contain copper (if it's a Tourmaline) but unfortunately that wouldn't be enough to give it the designated title of Paraiba.

Conchoidal fractures are often seen in quartz and obsidian (glass) to name just 2. Unless you've studied gemstones for a long time (under the microscope) it's almost impossible to distinguish between inclusions. Looking at both your Mother's rings, you can see that they are both virtually eye clean. For a Tourmaline of - I think you said 22mm - to be virtually eye clean is rare. If you had a stone that rare, would you put it in a massed produced ring shank?
I'm guessing that it doesn't matter what we tell you, you are convinced these are both Paraibas so I would really urge you to have some testing done as I mentioned in my post above. Good luck and I hope you find the answers.

In your first pic the stone looks like irradiated topaz. A beautiful stone and ring but it does look like Paraiba at all.
It seems to be very important to you that the stone is a Paraiba? I am happy for you that the GIA graduate could define in seemingly a very short time that the stone is what you wanted it to be. From the pic I do not detect the glow though
This GIA graduate made these conclusions based on pictures? Are you open to these stones being anything other than Tourmaline? If not then please say so and people will stop trying to guide you in the correct direction. You came here to ask for help. So I will say again, I do not think the pictures in your first post are that of a Tourmaline. Take the stone to a jeweler that can do a few quick tests, but only do so if you're open to the idea of these stones not being Tourmalines.P10431|1445979795|3942741 said:Just received a reply from a reputable GIA graduate who specializes in studying tourmaline, ruby and sapphire. He said my mother's ring is a PT and a beautiful neon color with enough saturation. For the other one, he said it could be a violet blue PT but they are very rare to find in a large size. Thanks for all replies, sayonara!
