J12-444 - Milarite - $ 750 Jaguaracu, Minas Gerais, Brazil thumbnail, 2.2 x 1.2 x 1.0 cm ex. Ron Pellar
A relatively large crystal of this very rare species, which only has been found in a few places in the world in such crystals. Of those, these large hexagonal crystals are the only ones a collector can even really expect to see periodically on the market, though even then it is a rare thing (they were brought out by Carlos Barbosa, I think, in the late 1980s or early 90s). Ex. Ron Pellar thumbnail collection. Joe Budd photos.
MD-159490 - Milarite, Adularia (Var: Valencianite) - - Archived Valenciana Mine, Guanajuato, Mun. de Guanajuato, Guanajuato, Mexico small cabinet, 6.7 x 6.2 x 2.2 cm.
6.7 x 6.2 x 2.2 cm. Milarite is a rare beryllium silicate. This is a classic, old-time and showy combination piece of a couple of pastel-yellow milarite crystals, to 8 mm, along the edge of a plate of off-white valencianite crystals. Valencianite is a unique variety of adularia (orthoclase) named after the famed Valenciana Mine at Guanajuato, Mexico. Ex. Harvard and George Elling Collections.
MD-180066 - Milarite, Adularia (Var: Valencianite) - - Archived Valenciana Mine, Guanajuato, Mun. de Guanajuato, Guanajuato, Mexico small cabinet, 6.5 x 4.3 x 1.6 cm.
6.5 x 4.3 x 1.6 cm. Sharp lemon-yellow crystals to 5mm of the rare species milarite. The milarites are embedded within and sticking out from matrix of crystallized feldspar var. adularia: referred to as "valencianite" by many because of the unusual lustre and form of the crystals compared to feldspar from other Mexican locales. Ex. Martin Zinn Collection.
MD-180865 - Milarite, Adularia (Var: Valencianite) - - Archived Valenciana Mine, Guanajuato, Mun. de Guanajuato, Guanajuato, Mexico small cabinet, 6.6 x 4 x 3.3 cm.
6.6 x 4 x 3.3 cm. Excellent gemmy yellow-green hexagonal Milarite crystals intergrown with white adularia. The locals call this adularia Valencianite, as its lustre and sharp rhombohedral form with a bit of a curve make it distinct from normal adularias crystals. The largest of the Milarites is .6 cm across and is classic for this well-known locality from old finds of the 1960s. Ex. Charlie Key.
MD-20137 - Milarite - - Archived Rössing Mine, Arandis, Swakopmund District, Erongo Region, Namibia thumbnail, 12 x 10 x 8 mm
A very well terminated, gemmy and lustrous milarite thumbnail crystal from Rossing, Namibia. Old material from the 1970s find. Ex Carlton Davis Collection # 311. 12 x 10 x 8 mm
MD-21349 - Milarite - - Archived Giuv Valley, Tujetsch (Tavetsch), Vorderrhein Valley, Grischun (Grisons; Graubünden), Switzerland thumbnail, 1 x 0.5 x 0.5 cm
A superb crystal for the species from ANY location but particularly from this classic Alpine locality. The quality of this crystal is very high, and it is more obviously gemmy in person. It measures 1 x 0.5 x 0.5 cm and is perched on a sprig of matrix! Esoteric and "just" a thumbnail, I admit, but an important specimen nonetheless. Interestingly, the "Val Mila" east to the Val Giuf was NOT the first locality for this stuff, though it is sometimes said to be. It is documented that the first findings were from Val Giuf but the finder labelled it Val Mila (to confuse the other Strahlers) , and hence the origin for the name "Milarite". Later Milarite was coincidentally also found in the Val Mila. 1 x 0.7 x 0.5 cm
MD-225217 - Milarite - - Archived Middle Moat Mt. locality (Moat Mountain), Hale's Location, Carroll Co., New Hampshire, USA small cabinet, 7.4 x 6.9 x 3.9 cm.
7.4 x 6.9 x 3.9 cm. This specimen is illustrated in Figure 18, page 294, of some old mineral book I have not tracked down yet, according to the note with the piece (if anyone knows, please tell me). The crystal spray is fully 2 cm, nicely protected in a pocket of feldspar and smoky quartz. Ex. Ken Hollman Collection. A note card with the piece, apparently from Ken, noted that this was bought from John Oliver, that it was "excellent," and that there is associated fluorite and also an unidentified mineral. He thought it worth noting that the piece had not been "acid cleaned" as well. A true East Coast rarity.
MD-232946 - Milarite, Adularia (Var: Valencianite) - - Archived Valenciana Mine, Guanajuato, Mun. de Guanajuato, Guanajuato, Mexico cabinet, 14.5 x 12.2 x 4.0 cm.
14.5 x 12.2 x 4.0 cm. The milarite crystals here, hexagonal crystals topped with flat yellow terminations, measure up to 6mm across. Their size for this locality is pretty good, but it is the richness and overall size of the specimen that makes the piece significant. Such pieces are few and far between, and quite old. Another such is illustrated in the Bancroft book, Gem and Crystal Treasures, from the mid-1980s. These Mexican pieces are unique for their association with beautiful contrasting crystallized matrix of porcelain-like adularia feldspar, referred to as valencianite until recently. Ex. Martin Zinn Collection.
MD-251120 - Milarite, Adularia (Var: Valencianite) - - Archived Valenciana Mine, Guanajuato, Mun. de Guanajuato, Guanajuato, Mexico small cabinet, 5.1 x 2.2 x 2.1 cm.
5.1 x 2.2 x 2.1 cm. A classic Milarite specimen from the Valenciana Mine in Mexico. This specimen hosts a few rather lustrous, hexagonal, soft yellow-green color crystals of Milarite sitting atop porcelain-like, lustrous, sharp crystals of Adularia (var: Valencianite) with Quartz. The Adularia from this mine was distinctive enough that it earned a honor of being named after the locality. The Milarite crystals measure up to 8 mm across, which is good sized for this locality in my experience. Ex. Brian Kosnar Collection.
MD-37773 - Milarite - - Archived Grischun (Grisons; Graubünden), Switzerland thumbnail, 1.7 x 1.4 x 1 cm
Rarely do you find Milarite crystals with such form, clarity, and luster in any size but a micro. And from this locality, they are most desired! This is a superb example of the species. 1.7 x 1.4 x 1 cm
MD-51262 - Milarite - - Archived Jaguaraçu, Minas Gerais, Southeast Region, Brazil thumbnail, 1.6 cm
Gorgeous, pale yellow crystals of milarite to 1.6 cm are really well-displayed on this miniature matrix. It is most unusual to get specimens with such a rich association - usually the milarites were found spaced out much more infrequently for the surface area. These are about 20 years old, and none of quality have been found since the mid-1980s to my knowledge. I think this is just a superb miniature for both the significance of the species, AND the richness and aesthetics of the piece itself. The crystals are also of large size for both the locality and for the species, surpassed only by a few freakish specimens from the Alps perhaps. 4 x 3 x 2.9 cm
MD16 - Milarite - $ 950 SOLD Strimthal, Graubunden, Switzerland thumbnail, 1.7 x 1.4 x 1 cm ex. Marilyn Dodge
Rarely do you find Milarite crystals with such form, clarity, and luster in any size but a micro. And from this locality, they are most desired! This is a superb example of the species from the TYPE LOCALITY in the mid 1800s
MRZ251 - Milarite on Valencianite - $ 250 SOLD Guanauato, Mexico small cabinet, 6.5 x 4.3 x 1.6 cm ex. Martin Zinn
Sharp lemony-yellow crystals to 5mm of the rare species milarite - from the only locale which really produces anything of beauty in North America, with the exception of a few grayish pieces from the East Coast's old mines. And these are not available either...I gather they came out in the 60s and 70s. Few turn up today for sale. The milarites are embedded within and sticking out from matrix of crystallized feldspar var. adularia: referred to as "valencianite" by many because of the unusual lustre and form of the crystals compared to feldspar from other Mexican locales.
MZTN-19 - Milarite on Quartz - $ 1250 SOLD Jaguaracu, Minas Gerais, Brazil thumbnail, 3.0 x 2.4 x 1.6 cm ex. Martin Zinn
This was purchased in 1999 directly from the collection of the deceased dealer Luis Leite, a well known specialist in rarities and in Brazilian classics after whom the species Leiteite was named. It is one of the finest examples of a Brazilian milarite I have come across, in any size, but happens to be a particularly balanced thumbnail specimen. Milarite is a highly coveted, yet rare, hydrated, potassium, calcium, aluminum, beryllium silicate. It is best known from the Alps and Brazil, plus a small 1970s find in Mexico. This specimen features a fine, lustrous and translucent, apple green, milarite crystal, measuring 1.5 cm in length, perched on quartz crystals, reaching 2 cm in length. Aesthetic and important! It is most unusual to get specimens with such a nice crystallized association - usually the milarites were found spaced out much more infrequently for the surface area and on generally ugly matrix (from all the locales). These are about 20 years old, and none of quality have been found since the mid-1980s to my knowledge. I think this is just a superb thumbnail for both the significance of the species, AND the balance and aesthetics of the piece itself. The crystals are also of large size for both the locality and for the species, surpassed only by a few freakish specimens from the Alps perhaps. They have excellent lustre and translucency, and it would be very hard to find a competition-level display quality thumbnail of such quality on the market today. Joe Budd photos
