4JG62 - Boracite (floater) - $ 750 SOLD Kalkberg, Lüneburg, Lower Saxony, Germany (TL) thumbnail, 1 x 1 x .8 cm
This is a remarkable and equant dodecahedron from the type locality! Good seafoam-blue/green color, good luster, and great form make this such a wonderful thumbnail! These are quite old and turn up now only in old collections. The cutting rough value of the specimen, because of the size and color, is considerable at around $500-600 wholesale.
4ZA3 - Boracite - $ 75 SOLD Boulby Potash Mine, Yorkshire, England thumbnail, 3.1 x 1.7 x 1.4 cm
Sharp, pretty crystals of this rare species, from a modern find at this old mine
LGC-01 - Boracite - $ 2000 Boulby Potash Mine, Loftus, North Yorkshire, England small cabinet, 9.4 x 6.3 x 3.7 cm ex. Lindsay Greenbank
Inside a hollow vug are individual crystals of glassy and gemmy, pastel green boracite, , to 4mm. This is a very rare magnesium borate. However, the crowning glory of this specimen is the unusual stalactite composed of super sharp and lustrous boracite crystals. This stalactite measures 2 cm in length and is highly unusual. Recovered in 1993 by the mine surveyor, this is a significant and aesthetic specimen.

Highly lustrous and translucent crystals of turquoise-blue boracite, to.5 cm across are clustered together in a vug. Recovered by a mine surveyor in 1993, this is one of the most brilliantly lustrous and intensely colored specimens we have seen. It is highly displayable, and a significant example from this brief find. Prominently featured in Minerals of Northern England, as a full page photograph on page 54 of that book. Joe Budd photos shown (bottom row).
LGC-40 - Hilgardite on Boracite - $ 1500 Boulby Potash Mine, Loftus, North Yorkshire, England miniature, 5.5 x 3.5 x 2.8 cm ex. Lindsay Greenbank
Emplaced on a vuggy matrix of massive boracite is a druse of lustrous, salmon colored crystals of hilgardite. These are quite rich and wellformed 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).
LGC-55 - Boracite - $ 2500 Boulby Potash Mine, Loftus, North Yorkshire, England small cabinet, 6.7 x 6.4 x 5.8 cm ex. Lindsay Greenbank
Lustrous and frosted, light green boracite crystals to 5 mm totally comprise this entire and very rich specimen. Recovered in 1993 by the mine surveyor, this is a significant, concentrated mass of sharp tetragonal crystals showing the classic form of boracite from this locale. Interestingly, these large nodules present a mining hazard because their hardness can damage equipment when veins are (were) hit.

Both species are here in excellent representation and in fact the hilgardite is unusually well-crystallized.
