7.5 x 5.0 x 4.8cm. A very sculptural and beautiful specimen of two pairs of translucent, brick-red aragonite stalactites on limestone from a most uncommon Montana locale - Carter County. Carter County is in extreme southeastern Montana in the Paleozoic Williston Basin, an area not known for fine mineral specimens. Obviously from a cavern there. Uncommon material collected long ago and now hard to obtain.
