Why Does Platinum Jewelry Cost More Than Gold Jewelry? — Sharon Z Jewelry

This is a concern that I get a good deal. And I get it – you can obviously see if you examine metallic selling prices on line that platinum is presently fewer costly than gold, and yet you go to invest in jewelry and the platinum parts value a lot more. What the frack?

The solution lies in a wee little bit of science and math.

It is What’s Inside of That Counts

The shortest answer is that platinum is extra dense and large than gold – pure gold, that is. 

But likelihood are that you are not searching for pure gold, you are probably procuring for 14 or 18 karat gold. 14 and 18 karat are both equally created up of pure gold that has been alloyed (blended) with other metals. That course of action of earning an alloy will lessen the density and bodyweight of the gold. This is because the metals that are blended in have an even decreased density than gold.

14 karat gold is pure gold, combined with a person or extra of the adhering to – copper, silver or nickel. To see the change between the most well known metals, listed here is a crowd-satisfying favorite – a checklist of well-liked metals and their density in grams for each cubic centimeter (g/cm3)!

As you can see, platinum is dense. Like, a full great deal of molecules for every centimeter. If you hold the correct identical piece of jewelry – just one in platinum and one particular in 14 karat gold, you can sense the difference in pounds.

Just appear at these excess weight dissimilarities! The specific very same ring, in the very same ring measurement, and the platinum model – even in a fragile ring – is nearly an entire gram heavier than the gold.
