Cost of Platinum vs white gold?

[jmarshall]

I am sure it varies based on several factors such as the current gold price, complexity of setting, etc... was wondering, is there some kind of baseline percentage to give an idea, without getting a price quote on every setting I look at?

A platinum setting is going to be approximately _____% more than the same setting in white gold.

Right from Whiteflash website

14K is 58.5% of pure gold
18K is 75% of pure gold if white gold mixed with other alloys as well...
platinum is 100% plat

today on the kitco market
gold 100% is 1570 an ounc
platinum 100% 1563

so they are basicly prices similar you have to figure out what 58.5% of pure is then you can calculate the difference in 100% pure plat. and 58.5% gold does that help

Is white gold or platinum better? It’s a very common question because both precious metals are popular for fine jewelry and both look very similar. But there are important differences to consider in making your choice. One is the difference between white gold or platinum in terms of price.

Looking at current bullion prices there is not much difference between an ounce of pure gold and an ounce of pure platinum, which leads people to assume the prices of a finished jewelry piece would be approximately the same in either metal. However, there are a couple of factors that create a significant price differential between white gold and platinum.

First, platinum is normally used in jewelry in almost pure form. Most platinum jewelry is between 90 and 95 % pure. And the most common metal mixed with platinum is iridium which is itself a very expensive metal. Gold alloys used in jewelry are normally used in purities between 41% (10 karat) and 75% (18 karat). And the metals mixed with the gold to make these alloys such as nickel and silver are relatively inexpensive.

The second reason that platinum jewelry tends to be more expensive than white gold has to do with the high density of platinum. The same ring will weigh significantly more in platinum versus white gold. Therefore, more metal with a higher purity is used in making a platinum ring resulting in a compounding cost factor in the white gold platinum difference.

Either a white gold or platinum engagement ring will look white and lustrous when finished. However, there are differences in the properties of the metals that should be taken into consideration. As mentioned there is a difference in density and weight, sometimes referred to as “heft”. The density differential starts to shrink with 18K white gold vs platinum as that alloy contains more pure gold which increases its density and heft. Some people prefer the substantial feel of platinum and the knowledge that it is used in almost pure form.

One reason it is hard to predict is that labor is a large portion of the cost of a ring, not just metal content. Also, different brands price differently.

This ring is $875 in 18k white gold and $1275 in 18k in platinum (about 31% more):

This one is $1675 in 18k wg and $1875 in platinum (about 10.5% more):

So with the less expensive solitaire, the price is $400 different, whereas with the more expensive solitaire, the price is only $200 different!

I guess I'll just have to wait for my price quote
