Research brings me to this: Fianit is a synthetic gemstone, primarily known as cubic zirconia (CZ), that closely resembles a diamond. It is a colorless and hard crystal, typically used in jewelry as a diamond alternative. The name "fianit" originates from the Physical Institute of the Academy of Sciences of the USSR (FIAN), where it was first synthesized.
So ice screw possibly made in Russia?
