The ArkenstoneFeatured
Emplaced on a vuggy matrix of massive boracite is a druse of lustrous, salmon colored crystals of hilgardite. These are quite rich and well-formed for the species, and are color-contrasted and associated with small, glassy, light blue boracite druse. Hilgardite is a rare, hydrated, calcium, borate. Recovered in 1993 by the mine surveyor, this is a significant specimen with large crystals for the species, and quite displayable. Illustrated in "Classic Minerals of Northern England," page 56, as a half-page photo (Joe Budd photo, shown here atop) .
