Spinel    Luc Yan, Vietnam    A really large TN cluster with crystals to 2 cm each on edge and overall measurements of 3.4 x 3.1 x 2.9.  It is damage-free and does fit in a perky box.  Reddish brown in color and mildly translucence.  An exceptional example, floater, highgraded from a lot of about 100 crystals several years ago.  One of only two specimen I felt worthy of a high end thumbnail collection.   280$
