Thank you Sante. I thought so too as I had never seen similar specimens before from Turt. Definitely a nice addition to the Romanian suite.

Quartz

Dimensions: 5.6 x 7.7 cm
Description: Colorless quartz crystals with a second generation overgrowth of iron oxide tinted red quartz. |
It's been 5 and a half years that Michael posted his avatar specimen as a large photo and while we discussed my new Alnif quartz I realized that I never commented on this one here. Lovely sculptural specimen, absolutely beautiful!
Btw, the green fluorite from Madagascar posted some weeks ago is also great, perfect specimen from that quite new find!
