Thanks Tobi! This piece looks so much better in hand than the photo conveys.

Superb photos, and I especially love the close-up shots. Not many people bother to take close-ups, but often they reveal so much detail about how the mineral was formed.

What a jewel! And I mean the crystals, not the cut stone ;-)
A highly aesthetic specimen with the best red colour you will find in the mineral world. No wonder that pieces like that from South Africa are among the most desired minerals!
(And a superb photo btw.)

Thanks Tobi and Dany! I have always wondered just how large the rough had to be to get a gemstone this large .....
