Very pretty  glassy Selenite crystals with accenting  Calcite, Sphalerite and Pyrite. Both sides present well.
Metaphysical Properties: Selenite opens, aligns and clears the aura.  It is used to clear the mind and expand our awareness of ourselves as well as our surroundings.  Senenite transmits light, energy and information which makes is useful for channeling as well as for healing.  In meditation it can be used to access past lives or future lives.  In healing, it can be used to remove blockages because of it's ability to transmit light.

Rare pink vitreous Hureaulite crystals crown a rock base.
Minas Gerais was formed mainly by colonists who searched for veins of gold and gems, and later diamonds. The name literally means general mines, a shortening from Minas dos Matos Gerais, or mines of the general woods, this being originally the hinterland to the incipient colonies of São Paulo dos Campos de Piratininga and São Sebastião do Rio de Janeiro (From Wikipedia, the free encyclopedia).
An old attractive specimen self-collected by Charlie Freed in the mid-60's covered with gemmy, orange brown Vanadinite crystals.

Outstanding specimen of well defined brassy yellow Marcasite crystals adorning a group of large silver gray Galena crystals. The most unique habit for Marcasite is its "cock's comb" twinned habit. The crystals appear like a rooster's head crest. The habit is very distinctive and can not be mistaken for any other mineral.
Metaphysical Properties: Marcasite  illuminates the senses and intellect, softening expressiveness and dispelling the use of rash words and impatient actions.  Marcasite represents spiritual development, eliminating starvation of the spirit.

Stunning cluster of "Tangerine" Quartz with no damage. Excellent !!
A fine cluster of light golden, pyritohedral Pyrite crystals. Not you average Pyrite specimen.
Rare light purple, gemmy crystals of Fluorapatite crystals (to 2.5 x1.5 x 0.5 cm), with internal zoning, nicely nestled on a Siderite matrix.
Super specimen of lustrous, blood red Realgar crystals on matrix. These are hard to come by these days and, of course, the Mines in Romania are now closed.
Nice cluster of pale blue-green crystals of Fluorite on pyrite.
Interesting specimen of native Copper (1 x 1.5 cm) on matrix with minor Quartz on from Spain.
Beautiful, glassy, double terminated Quartz crystal, with well defined faces and edges, from the famous Emilio Mine. Presents well from several sides and angles. In fine condition. The Emilio Mine is very well known for colorless Fluorite crystals but Quartz is very uncommon from that location.
Very aesthetic display of Quartz trimmed with Calcite on a large cluster of pyrite crystals.
A fine example of the complex mineral specimens that are more typical of the Panasqueira Mines. A 3 x 2.5 cm Siderite crystal sits amidst Muscovite, Marcasite, Arsenopyrite and smaller Siderite crystals.
We recently acquired the Collection of Jorge Diaz Asenjo of Oviedo, Asturias, Spain - a fine gentleman who built an excellent international collection over 20+ years, including many superb specimens from Spain and Portugal. We will disburse his collection over the coming months, mixed in with others obtained from around the world.
