Interesting little Porphyry tumblestones, measuring around 20-30MM along their longest point.
As our supply of these unusual tumblestones is limited, we sell them singly.
Porphyry is not a stone you often find tumbled or polished at all; although it has been used for carving and artifacts throughout history.
It is most often used for things like paving nowadays – you won’t find it faceted and cabochon pieces are rare too.
As a rule, it will typically only be sold rough to mineral collectors. There’s no reason collectors wouldn’t want a polished piece too, though.
