Description

Metallic inclusions of the extremely rare new selenide mineral nickeltyrrellite (IMA 2018-110) from the famous El Dragon mine in Bolivia (known for its paragenesis of selenium minerals) in a polished section of TWO completely analyzed samples by SEM/EDS, see copies of the analysis enclosed.

Only one locality known worldwide !!

Atomic and weight percentages in the analyses are only approximate since the sample was not carbon coated due to a requirement of the SEM/EDS machine.

Size is the size of the disc used for the analysis. Two specimens of nickeltyrrellite are enclosed in this disc, so they can be separated if desired.

Don't miss the opportunity to get this extreme new selenium rarity !
