Source volume: 52, issue: 2, PDF page: 42. Label: Figure 29. Two groups of large purple fluorite crystals to 4.5 cm with the color developed mostly along the crystal edges, from Larkin’s quarry. The crystals show variable development of dodecahedral bevels and distinct “Celtic cross” habit as a result of the cubic fluorite growing preferentially on the apices of an underlying earlier generation of octahedral crystals.
