SOLD Mimetite with Goethite
stock #SOLD 20.1-289
Preguica Mine, Sobral da Adica, Moura
Beja, Portugal
7 x 3.7 x 3.8 CM (cabinet)
price: $250
new year 2021

From Portugal, a very well-crystalized, delicate specimen of Mimetite from a locality we do not see often, but which is certainly an important deposit. Mimetite crystals are dense but well separated on all sides of this matrix with both yellow and orange colors. The matrix is a mix of bluish-black manganese oxides and Goethite which makes an excellent contrast for the Mimetites. Despite the obvious delicacy this is in excellent condition and the matrix seems to be quite solid and stable. Excellent addition for any suite of Lead secondaries, this is a very choice example from Preguica. Clearly unlike Mimetite specimens from any other locality.

Corkite on Plumbogummite and Goethite
stock #20.1-900 (ZS-CRK4099)
Serra Da Mina Mine, Cercal do Alentejo, Santiago do Cacem
Setubal, Portugal
7.3 x 5.8 x 4.2 CM (cabinet)
price: $1350
new year 2021

Corkite is a rare Lead Phosphate mineral related to Beudantite that is just never seen as display specimens. Most are micromounts where the tiny crystals can be mesmerizing. This piece is something else, a full cabinet sized top grade specimen with hundreds of gemmy Corkite crystals sparkling in an esthetic iridescent display. The matrix is a blue green to orange Plumbogummite and a chatoyant botryoidal Goethite which sets the Corkite off nicely. The Corkite crystals are sharp, glassy transparent in colors of brown, orange and blue that come alive under magnification. These are up to about 1 mm in size and most are well isolated, yet still densely covering the matrix. I have never seen another Corkite specimen that can be displayed and appreciated as an esthetic and very colorful piece in a mineral cabinet.

Apatite, Siderite, Quartz and Pyrite
stock #17.1-054
Panasquieira Mines, Panasquiera Covilha
Castelo Branco District, Portugal
11.1 x 8.3 x 4.2 CM (cabinet)
price: $390
new year 2021

A complex mix of sharp gemmy Apatites with Quartz crystals that are in turn covered with small Siderites and a sprinkle of Pyrite. From the famed Panasqueira Mine, this is both esthetic and has an unusual presentation. The Apatite (Fluorapatite) is vividly fluorescent and in fine condition.

Apatite (Fluorapatite)
stock #20.1-782
Panasquieira Mines, Panasquiera Covilha
Cova da Beira, Centro, Portugal
5.5 x 5.7 x 3.3 CM (cabinet)
price: $420
new year 2021

Sharp, glassy and transparent green Apatite crystals in a cluster that features a main 3.6 CM crystal perched on top. The Apatites are zoned, vividly fluorescent, and have just a sprinkle of matrix; this is mostly just Apatite. In very good condition, with just tiny edge bruises seen on close exam which keeps the price low for such good form and luster. Nice display quality Apatite from this iconic mine.

Apatite CaF (Fluorapatite)
stock #6.2-537
Panasquieira Mines, Panasquiera Covilha
Castelo Branco District, Portugal
6.2 x 4.7 x 2.6 CM (cabinet)
price: $360
Spring 2020

A main hexagonal Apatite crystal is well positioned on a matrix of Siderite and Muscovite. The Crystal displays well despite some bruises and a large contact on the backside. Close exam shows the many acicular inclusions of dark tourmaline and an unknown white mineral some of which are arranged in radiating patterns. Vivid yellow fluorescence with some color zoning is noted as well. Though not perfect as noted, as a result this is very affordable for the size and still looks like a more costly specimen.

Fluorapatite on Muscovite
stock #16.1-311
Panasquieira Mines, Panasquiera Covilha
Castelo Branco District, Portugal
5.4 x 3.2 x 2.6 CM (cabinet)
price: $400
Spring 2017

Sharp purple Apatites are scattered on a finger of fine grained Muscovite in an esthetic grouping. Crystals reach 1.7 CM and most show good color zoning. A choice small cabinet specimen that displays well from the classic mines of Panasqueira. One small contact can be found on a lower edge otherwise this is in perfect undamaged condition.

Apatite on Quartz
stock #15.1-342
Panasquieira Mines, Panasquiera Covilha
Castelo Branco District, Portugal
4.5 x 2 x 1.5 CM (miniature)
price: $600
Fall 2015

A very choice piece, this is a glass-clear quartz crystal hosting several purple gem Apatites. The Quartz is perfectly terminated, overall sharp and impressive in person, in very fine condition. Strong magnification reveals some tiny Siderite crystals. The Apatites have some slight zonation and have top luster. Not a typical Panasqueira specimen, and far more esthetic than average.
