Cerussite on Quartz - elongated sixling twins
stock #17.1-855
Pentireglaze Mine,Polzeath, St. Minver
Cornwall, England
9.3 x 7 x 6.7 CM (cabinet)
price: $240
new year 2021

An excellent old Cornish Cerussite with sharp crystals to 2CM long. The crystals are all twinned with most showing a complete sixling habit. These look like six spoked gears when seen on end. The matrix is mostly a vuggy Quartz with micro crystals sparkling on most surfaces. For such a delicate mineral this is in good condition. Hard to know the exact age of this specimen, it has an old collection number on it, the mine was most active in the mid 1800's but there has been collecting activity in more recent years.

Smithsonite
stock #20.1-890
San Antonio Mine, Santa Eulalia, Aquiles Serdan
Chihuahua, Mexico
9.5 x 7.4 x 3.9 CM (cabinet)
price: $1850
new year 2021

A superb Smithsonite from the San Antonio Mine at Santa Eulalia, Mexico. An older specimen that ranks among the best for the locality. This could easily be mistaken for a fine Kelly Mine Smithsonite as the vivid color and silky chatoyance on the Smithsonite is a perfect match. The only clear differences from a Kelly piece is the matrix which on this specimen is mixture of Gossan with blebs of Smithsonite. It is also far less expensive than usual for a Kelly of this quality. Simply beautiful and even better in person, the luster and deep color are exceptional from this locale. A great addition to any Mexican collection or Smithsonite suite.

Stibnite - flower form of radiating crystals
stock #18.1-301
Herja Mine, Chiuzbala , Baia Mare
Maramures, Romania
8.8 x 6.5 x 5.5 CM (cabinet)
price: $490
new year 2021

A classic form from the Herja Mine in Romania, this is a flawless and very sharp Stibnite ball. The individual crystals are highly lustrous, gun metal blue-black to silver that reflect colorful highlights in person. The matrix is a solid crystalline Silicate that is a complete floater, micro crystallized on all sides. Unusual and especially eye-catching in person. The ball is 2.3 CM across and impressively undamaged.

Mcguinnessite
stock #0888-JM-3125
Miners Ridge, Red Mountain, Mendocino County
California, United States
7.2 x 4.9 x 3.3 CM (cabinet)
price: $90
new year 2021

A good sized blocky matrix with Mcguinnessite in rich crystalline crusts on several faces. Ex John Marshall collection, this is from the type locality area of Red Mountain. Close exam shows there are many tiny spheres and cups of blue green mineral, as well as some massive zones. A nice example of this unusual Copper mineral.

Cubanite - classic twinned crystals
stock #AX-29-091
Henderson Number 2, Chibougamau
Quebec, Canada
2 x 1.3 x 1 CM (thumbnail)
price: $1400
new year 2021

Cubanite twin crystals in a cluster with virtually no matrix. In fine condition as seen, such good Cubanite crystals have become quite rare as it has been over two decades since the last of this world class find. This one shows excellent golden luster and form, the largest crystal is a full sixling twin. It is very unlikely there will ever be more of this quality found. There are several localities in the world for this mineral but any crystals are very rare and almost all are micros. These Canadian specimens are the by a wide margin the best in the world, and good twins are especially scarce now.

SOLD Paradamite
stock #SOLD 20.1-897-(ZSPRA4105)
Mina Ojuela, Mapimi
Durango, Mexico
4 x 2.8 x 1.3 CM (miniature)
price: $0
new year 2021

Miniature specimen densely covered with bright, glassy crystals of Paradamite. A choice piece of this highly desired rare species from Ojuela. This specimen has been in the J.A. Dague, Dr. Herman March and the Terry Szenics collections. In fine condition, the crystals are very sharp and gem clear. Older specimen from the early find, the matrix is typical gossan but stable and solid without any crumbling.

Digenite with Pyrite and Quartz
stock #0445-JM-2361
Leonard Mine, Butte, Silver Bow County
Montana, United States
7.7 x 6.1 x 3.8 CM (cabinet)
price: $540
new year 2021

A choice and classic Butte specimen of Digenite crystals on a contrasting matrix. Normally Digenite is an unattractive sooty black rarity, loved only by serious Sulphide lovers (like us). This specimen is very much nicer, and actually displays well. These crystals are quite good sized, and are well set on a sparkling bright contrasting matrix. The crystals of Digenite are usually rather crude and these are too, but still have a distinct form showing structure. The largest crystal is about 1.5 CM across. Contrasts well with the sharp and bright golden Pyrite. In excellent condition, this is ex John Marshall Collection with his collection card. He obtained this in 1979 from A.L McGuinness and that label is also included.

Fluorapatite with Elbaite
stock #20.1-085
Pederneira Mine, Sao Jose da Safira, Doce Valley
Minas Gerais, Brazil
6.3 x 4.3 x 4.7 CM (cabinet)
price: $1650
new year 2021

A very fine, super colorful and very unusual Apatite from the famed Pederneira Mine. The Apatite crystals show several generations of growth and color zoning quite different from the tourmaline the mine is famed for. This specimen also has a bi-colored, doubly terminated Elbaite crystal on the backside that is 4.7 CM long, a nice addition. The Apatites have sharp flat terminations and colors zones in purple, blue, orange-red and some dark green. These also show well some selective growth and etching with areas of re-crystallization. This makes for a complex and especially interesting presentation that looks fine from several angles. Excellent condition with no damage, this is the best Apatite I have seen from Pederneira, and would be a fine piece from anyplace. Vividly fluorescent with a zoned responses corresponding with the daylight color areas.
