While, of course, you don't buy jewelry just for the sake of its intrinsic beauty, but for wearing it, and, as such, you have to perfectly match it with your skin tone, haircut, clothing and other accessories.
There are some properties of the precious metals it is made of you should be also aware of, given that you don't want to face allergies, high maintenance or the impossibility of its modification, if the need arises.
After all, the difference between white gold and yellow gold jewelry consists of neither the amount of gold contained, nor of its purity, if the karats are identical, but of the color, accountable for by the alloys used in combination with gold.
White gold is alloyed with silver and palladium, while yellow gold with copper and zinc.
It's exactly because of the allergies that it had often provoked that nickel is no longer mixed with white gold these days.
Besides being accountable for the different shades, these alloys transmit some of their other properties to the end metal.
As such, white gold is harder, therefore resisting better to scratches or marks than yellow gold, on which these may look quite visible.
As regards their maintenance, white gold would normally look light gray, if it wasn't for the coat of rhodium applied, which gives it its silvery shine.
But if you don't want this shade to fade over time, you need that coat renewed every year.
Yellow gold, on the other hand, has to be polished regularly for its sheen to appear fresh.
Why would people prefer then white gold at all, if they are after the silver shade that it's so to speak added? Well, titanium or platinum might look naturally so, but are far more expensive.
And, besides, the first cannot be modified at all, and the latter rather with difficulty, because they are too hard.
So imagine an expensive engagement ring you cannot longer wear because you lost or gained some weight! Also, why would people prefer white gold over yellow gold, for instance, as regards engagement rings? Well, that's simple: its 'neutral' color is not likely to set a different color on the stone, in this case some white diamond, making it look unpleasantly yellowish.
Besides, people with pale skin, for example, would look downright sallow, if wearing yellow gold pieces of jewelry.
Therefore, when choosing your wholesale jewelry, you should consider both your own features and the properties of the precious metals it is made of.
