Hi Silvia,
I appreciate your nice comment about my Trepca specimen. The property that attracted me to the Ludlamite was its gemminess.
Regards,
Don

Tobi, thank you for your comment. I was pleased to find a spinel twin and cubic copper crystals both in the same specimen.

Nice colours on that agate, Don. You know I recently discovered agate as an interesting mineral for me, nice to see I'm not the only "serious" collector here with a weakness for polished pieces of microcrystalline quartz ;-)
