Polished Madagascar Septarian Stones (1 lb)

These Curator’s Choice Madagascar Septarian polished stones highlight the bold, natural patterning septarian is known for—warm calcite tones framed by darker mineral lines in striking, one-of-a-kind designs. Formed as a septarian nodule within sedimentary layers, each piece features the signature “crackled” look created when natural shrinkage fractures were later filled with mineral-rich material. A great fit for collectors and geology lovers, these polished stones bring an authentic glimpse of sedimentary formation and mineral movement—beautiful in-hand, and equally at home in a display tray.

Sold by the one pound in a drawstring jute gift bag. Stones are approximately 1.75" to 2.4", averaging about 4 - 5 stones per pound.

Most shops sell tumbled stones individually for about $12 - $18 each. By offering these stones by the half pound, you get a generous assortment at a fraction of the per-stone price.
