Hi Am. Thank you for showing your beautiful specimens. I find this specimen (QtzTanDetail.jpg) very interesting. See the 3 small triangles are in line with the inclusion. I presume that the 3 triangles are of the quartz. How deep is the included mineral beneath the surface? Is it possible to post a close up of this?

Pierre - Here is a close up of that section of the crystal. This particular inclusion is very near the surface. It looks like it is no more that 1 mm from the surface.

Hi Am. Thank you for posting the photo. I am particularly interested in why the triangles are in line with the included mineral. Regards.
