That would be my guess as well. The structures right. The other possibility is tourmaline however the fracturing and termination are wrong. Nice stuff. If ya had not said ya got it from an estate sale I'd have guessed you'd gotten it from your mine in the other thread. Now that would have been odd Never heard of finding red and blue/green berly's in the same mine.
Isn't beryl a different shaped crystalline structure than tourmaline? I'm not sure atm.
I just said something on your other thread about red beryl. Hmmmmmmm
Great finds, whether beryl or tourmaline.
pat,
I've seen tourmalines with very similar shape to beryl's but yes typically tourmaline has a more rhombic shape and in large pieces shows a lot of striations along the flat surfaces. Only seen it in smaller crystals however. such a large piece though.... beryl
Your right, pat. Tourmaline is trigonal while beryl is hexagonal in terms of crystal structure. But, just as DD said - they can look quite similar.
That said, red beryl is very rare. IF it's beryl its a real find, but the odds are against it.
I'd for sure have a professional look at it in this case!
Leaning towards tourmaline here. If that matrix is rhyolite, red beryl - and would likely be from the wah wah mountains in Utah. If it's pegmatite, tourmaline -- likely out of Pala, Ca.
If it's red beryl then Wow! I went mining for this a few weeks back, but that would be an unusually large specimen. If it's truly a red, that estate didn't know what they gave up.
