Yes. This is because the nickel combined with gold to make white gold. All pure gold is yellow, and white gold is made by alloying the gold with whitening agents such as nickel or silver. There is no isotope of gold that is white and by adding nickel or silver white gold becomes harder than yellow gold.
No
White gold can cost a little more than yellow gold but not prohibitively so.
Pure yellow gold is more expensive than an alloy.
Your gold choice color is a matter of preference. White gold is enjoying greater popularity right now and may sometimes be more expensive, but this is really more a matter of demand and what sellers know they can get. As far as why white gold is white and yellow gold yellow, it's all a matter of the kinds of metal alloys that are combined with pure gold, which is naturally yellow but may be altered. Also, pure gold is too soft not to combine it with other metals for strength.
It is the quality of the diamond that makes it sparkle not so much whether the setting is white or yellow gold

There is no price value difference between the actual gold in white and yellow gold jewellery, as long as it is hallmarked at the same carat weight. So for example, 18K white gold and 18K yellow gold will contain the same percentage of gold.

It depends on the grade of the gold, usually yes.
White gold is an alloy of gold and at least one white metal, usually nickel or palladium. Like yellow gold, the purity of white gold is given in carats: 24 kt is pure gold, 18 kt has 18 parts gold and 6 parts of another metal, so it is 75% pure.Since nickel is cheaper than gold this white (alloy) gold is cheaper than the yellow pure variant. The price of palladium is unknown to me, so I can't figure it out.
Yes, unless you ejaculate on the yellow gold and turn it white and freeze it. then they break even.
Silver is softer than 18K gold.
