This exquisite specimen of splendent, silvery gray acanthite features two dominant, well formed cubes, to 1.2 cm across. They perch atop an elongated acanthite crystal that acts as a natural pedestal and that looks like it is curving, and is very elegant. Ex. John Barlow collection and featured in his book on page 243, plate # 10-10. An exceptional competition quality acanthite miniature!
