Nice garnet crystal Pierre! The cut stones are very attractive.
I didn't know there were such large gemmy andradite crystals from Namibia.
Best regards, Mike

Hi Mike, Thank you. The cut stones are not top quality and the total weight is 4.5 ct. Best regards.

A smoky quartz specimen with chlorite.
I want to bring to attention (to the administrators) that Kakamas is just a small town near the Orange river and insignificant when it comes to mineral specimens, save that a mineral dealer is situated there. The correct wording should be 'Orange river pegmatites, Northern Cape, or Namibia' as the Orange river is the border between the 2 countries.
| Mineral: | Quartz with chlorite |
| Locality: | | Orange river pegmatites, Kakamas, ZF Mgcawu District, Northern Cape Province, South Africa | |
|
| Dimensions: | 56 x 52 x 43 mm |
| Description: |
| This type of specimens are not very common from that area. |

| Your collection is exotic, I can only wonder what rocks and minerals in Africa are waiting to be discovered.I could imagine that the story behind the rock, that of the collector, is equally fascinating.

Hi Frank, I feel honoured to have this kind comment on your first post on FMF. Thank you :-)
I agree, if a rock could speak, some would have fascinating stories; some of greed and theft; others of joy.

Thank you Reinhardt. Here is a small specimen with a story. We purchased this little specimen at Uis a number of years ago. It is seldom that you find small delicate clusters like these from Brandberg. I photographed it, but later I was dissatisfied with the photos and I wanted to photograph it again. While I attempted to do so, it dropped just a few cm and broke in 3. Fortunately I still had the old photos, which now was valuable. I reassembled it and now it is in our collection; repaired like most of us.
