OKN-703     Tourmaline with Quartz      Minas Gerais, Brazil.  Ex. Harold L. Dibble collection.  One of his finest specimens this huge crystal cluster measures in at an impressive 58 cm long.  It probably weights in at approximately 100 to 150 pounds as I can just barely lift it waist high.  The main quartz crystals are double terminated and heavily encrusted by and included by large green tourmalines to 16.5 cm long and over 3 cm wide each.  The base termination and what I would call the top (top in the first two photos with myself) have very attractive watermelon crystals that are among the largest crystals in the quartz.  The back side is more heavily coated with a thick aggregate of tourmalines of all sizes.  The tourmalines are for the most part transparent with bigger ones being translucent.  The green is quite dark by very clearly GREEN, not black.  It is likely that many more of the crystals are watermelons (having pink cores and green rinds) but unless they are broke it is difficult to tell with casual viewing.  The luster on both the quartz and the tourmalines is excellent.  I just washed the specimen before the photos were taken but the specimen IS DRY, not wet.  The photos are obviously not studio pics and this is all the photographic work I am willing to put into this piece.  It is simply too difficult to move around.

There are plenty of tourmalines that are not terminated but equally as many are.  The terminations are crude to very nice depending on the crystal.  The quartz is in excellent shape with far less damage than would be expected for a specimen of this large a size.  The top and bottom terminations each have a small area with chipping... very minor.  I will not ship this piece so it is for pickup here or at a show I do.  A reasonably close personal delivery could possibly be arranged for a small fee.  A dolly is required to move this specimen and it is very difficult to move floor to floor (but is possible with effort). 

The piece is most suited as a large home decor or museum piece.  When properly lit and backlit it glows!  Fantastic display piece.    $6,000
