Yes... and I lost my tugtupite last week
Small piece, very expensive, very rare, my fav shop doesn't even have them anymore at the mo. Only had a few pieces that came out of a private collection ... they can buy more, but then it'll be even more expensive...
... And I lost it!! *bangs head against the wall*
I find both tugtupite and cryolite very subtle in there energies, but can be me as well, maybe I cannot fully grasp their energies yet. But I did know I needed them, so I got them. Also cos of what you can do with them in combination with nuummite.
I still hope I will find my tugtupite, but it's only some 2 x 2 cm and maybe 3 mm thick.
