I have not seen many beryl crystals with hollow cavities (or tubes) that long. It's down to the lower halve of the front crystal... or maybe even more? Very likely due to a rapid growth mechanism...
Very nice Don!

Hello Gerard,

You have good eyesight. The tubes of larger diameter are more than half way down the twin crystals, but there are finer tubes lower down. It is very nice to hear from you.

Regards,

Don

Marvelous!
One of best off matrix chinese stibnite I've ever seen.
As Tuscany has had many stibnite mines, this mineral is one of my weaknesses...
Congratulations and warm greetings.
