This is an exquisite miniature highlighted by a very lustrous, black crystal of neptunite, measuring 2.7 cm in length and elegantly nestled in a vug of natrolite. On either side of the neptunite crystal is a lustrous blue benitoite crystal, each measuring 9 mm in length. Ex. John Barlow collection. Note that this is still attached to his display competition base which he would have used when exhibiting his core thumbnail collection in Tucson in the 1990s!
