Trinitite is sold by size:
1 gm. - 3 gm. pieces @ $12/gm.
3.1 gm. and larger pieces @ $15/gm.
All the trinitite sold here is from the Wallace T. Smith collection unless otherwise noted. This collection has been documented and written about in the book: "Trinitite, the Atomic Age Mineral". This material is limited and once it is gone, there will be no more. I also offer wholesale specimen trays. I try to note all special features of each piece of trinitite in the specimen description. All specimens come with a printout of the test results confirming the authenticity of the trinitite, and an ID card to display with your specimen.
