Because of its low cost, durability, and close visual likeness to diamond , synthetic cubic zirconia has remained the most gemologically and economically important competitor for diamonds since commercial ...
Commercial non-nuclear grade zirconium typically contains 1–5% of hafnium, whose neutron absorption cross-section is 600 times that of zirconium. Hafnium must therefore be almost entirely removed (reduced to < 0.02% of the alloy) for reactor applications.
