All of the specimens on this page, as well as the next two pages, are on consignment with me.    They are in the collection of an advanced collector (who wishes to remain anonymous) who has a fine eye for aesthetics & rarity, and also appreciates the pedigree of specimens.   I think you'll find a good mix of minerals on these pages with the qualities I just mentioned.

C1    Phosgenite - Montiponi, Sardinia, Italy     $400;    The main phosgenite crystal is gemmy, and features great striations on some of the faces.   It also has some inclusions running through it, which really adds interest.   Several more larger (and a multitude of smaller) phosgenite crystals fill the vug, which is in a galena matrix.    Overall this is a very fine example of this Old World classic.    Previous label from "Classic Minerals".    7 x 4 x 4     Reserved

C2    Wendwilsonite - Bou Azzer, Anti-Atlas Mountains, Morocco    $200;    Very closely related to Roselite, Wendwilsonite was only approved as a mineral species in 1987, and is named for Wendell E. Wilson; mineralogist, editor, and publisher of the Mineralogical Record.   This specimen features a vug filled with colorful, sharply terminated crystals to .7 cm.   Previous label from "Trinity Minerals".    4 x 4 x 2     Reserved

C3    Bobierrite & Girvasite - Zheleznyi Mine, Kovdor, Kola Peninsula, Russia    $165;    Very choice sharply terminated light grayish-blue bobierrite crystals are growing with botryoidal girvasite.   Kovdor is the type locality for both of these rare phosphate minerals.   Actually, bobierrite is considered "rare", while girvasite is "very rare".   Bearing a previous label from "Trinity Minerals", this is an extremely fine combo specimen of these rare minerals!    5 x 3.5 x 2.5     Reserved

C4    Manganite - Ilfeld, Harz, Germany     $200;     Ilfeld is THE location for fine manganite specimens, period!    This specimen features a vug filled with lustrous well terminated upright standing crystals on the main display side, and a second shallow vug with smaller manganite crystals with barite cleaves on the reverse side.   Previously in the Gilbert Gauthier collection.    6.8 x 4.5 x 4

C5    Hausmannite - N'Chwaning Mine, Hotazel, South Africa     $250;     Very sharp, much more lustrous than normal hausmannite crystals totally cover the display surface.   A few small manganocalcite crystals add some good contrast.   An absolutely superb miniature!    Previous label from "Classic Minerals".    5.5 x 4.5 x 1

C6    Rutile after Brookite - Magnet Cove, Arkansas     $75;     The three main crystals are very nicely positioned for display.    The crystal on the right shows the classic cyclic sixling twinning, although most of the lobes are imbedded in the matrix.   This crystal has a small nick on it's right side.   The other main crystals are in excellent condition.   The indentations that you see on them are natural faces, and are definitely not damage (I checked them under my microscope).    All of the rutiles are lustrous, and contrast well with the associated quartz crystals.   Some of the quartz crystals are dinged, but the rutile crystals are definitely the center of interest on this specimen.   Previous original label from "The Showcase" states that this specimen was collected in 1971.   The label shows a $35 price, a fairly hefty price for a relatively recent specimen back then!    3.5 x 3 x 3    Reserved

C7    Azurite - Tsumeb Mine, Tsumeb, S.W. Africa     $175;     Previous label from Mike Bergmann (when he lived in Deerfield, Illinois), plus two older labels from William Sanborn state the country as South West Africa, add up to tell me this azurite was probably collected pre-1970.    William Sanborn is the author of several noted mineral books, of which my favorite is "Oddities of the Mineral World", which focuses on topics like pseudomorphs, phantoms, and twinning.   Anyway, this is an extremely fine azurite specimen!   Highly lustrous single and double-terminated crystals form a mound that is displayable nearly all around, with only a small portion in the back that shows some contacting (not damage!) which stunted crystal growth.   Under strong light the dark royal blue crystals show electric blue internal reflections.   The largest crystal is 1.8 cm long.    3.5 x 2.5 x 2.5    Reserved

C8    Hutchinsonite - Quiruvilca, Peru     $225;     The display face is nearly totally covered with hutchinsonite crystals, a rare lead thallium arsenic sulfide.   Many of the crystals are growing randomly, but there are also numerous "bowtie" or "wheat sheaf" clusters.    Overall this is a very good example of this rarity.    5 x 3 x 2    Reserved

C9    Ilvaite & Quartz - 1st Soviet Mine, Dalnegorsk, Russia    $175;    3.2 cm and 1.7 cm long double terminated ilvaite crystals are the stars of this specimen.   Several smaller ilvaite crystals and some associated quartz crystals fill out the rest of this wonderful display piece.    Previous label from "Fabre Minerals"    4.8 x 3 x 2    Reserved

C10    Clinoclase & Olivenite - Majuba Hill Mine, Pershing County, Nevada    $500;    Very fine clinoclase crystals liberally fill the shallow vug of this specimen.   The crystals are lustrous, well formed, and large (to .7cm) for the species.   This is an extremely fine clinoclase specimen, which even looks better in person than in the photos!   It's quite possibly one of the best ones ever found at this classic locale, and for that matter anywhere in the US.   The owner told me that he's seen one better from the US.   That specimen is in the Harvard collection, and is from Tintic, Utah.   Ex Phil Scalisi collection, with his label.    5.5 x 4 x 1.5    Reserved

C11    Roselite & Dolomite - Ahrbar, Bou Azzer, Morocco     $200;     Beautiful magenta colored roselite crystals contrast well against the tan dolomite crystals.   The roselite has good luster, and as you can see the crystals are well formed.   I think this is a well balanced display specimen.    Previous label from "Fabre Minerals".    5 x 3.5 x 1.2
