Explanation:

Metals in columns 10 and 11 of the periodic table like gold (Au), silver (Ag), platinum (Pt) etc. are preferred for jewelry as they are lustrous, malleable, ductile and less reactive, maintaining their appearance over time. They are also relatively rare which adds to their value.

Answer:

These metals are lustrous, malleable, and ductile.
