This specimen presents isolated, intense yellow crystals of sulfur on stark white matrix of spiky little aragonite crystals. The crystals are to 3 cm in size, and pristine despite the age, and the softness of fragile sulfur crystals. This is a display-quality example of this CLASSIC material, now seldom seen in this quality for sale. A lot of more recently mined sulfur specimens was available briefly in the 1970s, and also some notorious fakes created around the same time. This piece, however, dates back firmly to a major multigenerational collection of Milan that was assembled in the second half of the 19th century. It has been confirmed as a valid historic specimen by Dr. Federico Pezzotta of the MUSEO DI STORIA NATURALE in Milan, which has an extensive comparative collection. Comes with custom lucite display base
