Question:
Are the men allowed to wear a ring made of WHITE GOLD?
Answer:
All praise be to Allah.
White gold is produced by adding some other types of metal, such as nickel, to pure gold, in order to give it a whitish color.
However, the color of the gold does not affect its ruling. It is still haram and forbidden for men to wear, whether it is a ring or otherwise.
For more information, you can listen to the lecture on Why gold and silver are prohibited for men in the Fiqh of Tahara lectures.
Note that some people refer to platinum as ‘white gold’. In the case that the ring is free from any actual gold, it is permissable to wear.
And Allah knows best.
