Gene & Sally LaBerge Collection Good tourmaline crystals from the Stewart Mine are relatively rare on the market, and this one collected in 1989 is a fine one. This gemmy crystal is zoned with pastel pink and green bands, and has a touch of cleavelandite at the base as an added highlight. When we acquired the specimen we noticed that the cleavelandite was glued on to the base, but not very elegantly so we removed the glue and re-repaired the specimen.
