Brazil has supplied collectors with wonderful mineral specimens for decades.  The gem material such as tourmaline, aquamarines, and topaz receive most of the acclaim, however there are a great diversity of Brazilian minerals worth noting.  Because we purchase older collections we often have fine examples of Brazilian minerals that are not common in today's contemporary mineral market.

OKM-820     Quartz   Brazil.        Ex. Harold L. Dibble collection.  FIGURED SPECIMEN from the book, Quartz: An Introduction to Crystalline Quartz, page 83 By Harold Dibble.  This fine specimen is a full page figure in Harold's book, and an impressive quartz specimen in and of itself.  It is a floater measuring 17.6 x 11 x 7.5 cm.  The crystal is double terminated, has a medium to high luster on it's upper display surfaces and a lower luster on what I would call its base (back side).  There are several chips as seen in the images so it is in good, not great shape.  The surface growth features are quite amazing and even better in person.  Everything here is in parallel growth on the one crystal.  $1,200

OKN-712

OKN-712     Tourmaline    Aracuai, Jequitinhonha Valley, Minas Gerais, Brazil.  Ex. Harold L. Dibble collection.  Finding miss-sharpen tourmaline crystals is not all that uncommon but one of this size and high quality is truly unique.  It was one of the centerpieces of Harold's collection.  This single terminated crystal  is 28 cm long (almost a foot!) and the primary crystal is 3.5 cm wide and 2.1 cm thick on average.  It is very high in luster and one side crystal is clipped off, a likely contact.  I'd describe it as damage free.  It displays great from any direction.  The curve is not what is commonly seen, a healed break or series of breaks.  It is just simply curved... smooth, symmetrical and spread over the entire length of this massive crystal!  The termination is complex and generally fibrous in form.  All the prism faces show moderate striations.  This is one of those specimens that collectors simply go, "Wow"! and stare blindly at.  Even better in-hand.  $3,000

Large Enhydro.

OKM-131    Quartz     Minas Gerais, Brazil.  Ex. Harold L.

OKM-121

OKM-121     Tourmaline, Quartz, Muscovite     Virgem da Lapa, Minas Gerais, Brazil.    Ex. Harold L.
