Margarosanite - Sold
- 3.3 by 2.7 by 1.7 cm – Thumbnail specimen (fits into a 3 cm cube)
Margarosanite is a calcium lead silicate. Ford and Bradley (1916) described the mineral from Franklin, New Jersey. The name follows from the Greek for pearl and tablet, which aptly describes this specimen as well. Here the mineral forms platy crystals to 1.5 mm in a pocket in skarn matrix. This is an excellent example of the mineral species.

There is a label indicating that this piece was in the Colonel Washington Roebling collection. Merrill's collection card and label also ship with the specimen.
