Not with a microscope but pretty clear. This is a piece of JXR Amethyst I just finished. There are 3 different planes of bubbles in this piece.

The lower one is really a great plane. The upper is where 2 different waves kind of cross.

Stats, 11.65ct ~15mm

Thanks for the comments. That stone as a GO pedigree. Amethyst Guy (Jason) found it.

From maialetto's crystal genomics company: the DNA of topaz revealed! :D

This crystal avoided the cutting lap so far, since I definitely had to take a pic of this inclusion.
It's parallel to the c axis. Unfortunately, I don't think this could be the "hole" of a huge growth spiral (no traces of the typical features on the pinacoid), otherwise this crystal would have been a fantastic keeper. :!:

Pics with different lighting/mag:

That is truly fantastic. Anyone know what this really is? I've never seen anything like that before.

John Koivula describes inclusions with a similar appearance in Photoatlas Volume 2, page 756.
It is described as follows:

The complex corkscrew structure in a Brazilian Topaz results from a combination of growth, breakage and etching.

Gemca (aka Jean-Marie Arlabosse) on his site www.geminterest.com has a similar picture displayed under Topaz Inclusions:

The inclusions above are described as follows:
Jean-Marie Arlabosse wrote:
Inclusion de type: 'solide', de nature: 'dislocations ayant suivi la croissance du cristal', à aspect: 'vis sans fin'.
Transmis / Darkfield / Transmis et filtres polarisants croisés ~40X<

As I understand, " Inclusion of the type: solid in nature consisting of dislocations following the growth of the crystal, appearing like a neverending screw. Transmitted/Darkfield/Transmitted and cross polarizing filters. 40X"
