Tucson 2020 Update

TT56AL1: A novelty at Tucson 2020. Doubly terminated floater crystal with very well defined faces and edges and two different terminations, one of them polycrystalline and the opposite end with a very deep hopper. The crystal is grey-green with bluish tints, has an intense luster between vitreous and silky, and is much more transparent than usual in specimens from this area. From a very recent find, with a quality superior to what is generally known in St. Lawrence County.
Big Mole claim, West Pierrepont, St. Lawrence County, New York  USA (06/2019)

Specimen size: 2.4 × 1.1 × 0.7 cm = 0.94” × 0.43” × 0.28”

TF50AL1: A novelty at Tucson 2020. Doubly terminated floater crystal, with very well defined faces and edges and with two different terminations, with rough faces. The crystal is grey-green with bluish tints, has an intense luster between vitreous and silky, and is much more transparent than usual in specimens from this area. From a very recent find, with a quality superior to what is generally known in St. Lawrence County.
The specimen has been reviewed, photographed and published as a novelty from Tucson 2020 in the Russian magazine ‘Mineral Observer’ on page 62 in the volume 25, number 2
Big Mole claim, West Pierrepont, St. Lawrence County, New York  USA (06/2019)

Specimen size: 3.6 × 1.1 × 0.8 cm = 1.42” × 0.43” × 0.31”

TF48AL1: Very 3-dimensional growth of Malachite pseudomorphing equidimensional crystals of Azurite, with very well defined faces and edges, intense color, on matrix. Before the Azurite started altering to Malachite a thin dark coating, probably Cuprite, formed on the faces of the crystals, as suggested by the mineralogy of the locality and some of the crystalline forms, apparently octahedral, present in the matrix.
This great quality piece comes from the collection of Rock H. Currier (No. 4667) whose label we will send to the buyer.
The specimen is from the Ignacio Gaspar Sintes collection, whose label we will send to the buyer.
