Calcit xx<br>
Ich habe ihn aus einer Sammlungsauflösung. Ursprünglich stammt er aber aus Shangbao, Hunan in China.<br>
Schweren Herzens möchte ich den wunderschönen Calciten weiterziehen lassen, deshalb findest du ihn ab jetzt im <a href="https://pixelfed.social/discover/tags/Hollenkraut?src=hash" class="u-url hashtag" rel="nofollow noopener" target="_blank">#Hollenkraut</a> Shop.

Erbse // HollenkrautEin großer Brocken Rauchquarz mit Mikroklin-Kristall an der Seite. Er war durch eine Sammlerauflösung zu mir kommen, stammt aber ursprünglich aus Mt. Malosa, Zomba in Malawi.<br>
<br>
Da ich durch einen bevorstehenden Umzug gerade ein bisschen meine eigene Mineraliensammlung verkleinere, ist der schöne Rauchquarz seit eben im Hollenkraut-Shop. Die nächsten Monate kommen bestimmt immer mal wieder welche dazu.<br>
