Is it permissible for a man to wear Chinese gold (plated only with gold color)?

Women are permitted to wear gold absolutely, whether it is real or plated, unless it causes harm or is worn for ostentatious display in front of non-mahram men. As for "Chinese gold" for men, if it is not real gold but merely resembles it, the general rule is that it is permissible for them, provided it does not lead to imitation of women. It is advisable to consult sellers to ascertain its true nature.
