Difference Between White Gold and Platinum (With Table)

Metals and non-metals are the elements that can be found in the earth’s crust. Some of them are naturally occurring but in the impure or mixed form, which is then refined to purified to obtain the required form. Some of the metals are inert and very hard, lustrous, malleable such as – Silver (Ag), Gold (Au), Platinum (Pd). These metals come with different prices and purity standards. The more the pure form, the more is the price.  

White Gold vs Platinum

The difference between White Gold and Platinum is that White gold is combined or formed by mixing other metals or elements in its chemical structure to form it, whereas comparatively, on the other hand, Platinum is the pure form of the metal and doesn’t have any impurities within it. The white gold is obtained after mixing the yellow gold (original color) with the palladium metals, which makes it obtain the white color, whereas comparatively, Platinum is naturally occurring in white color.

White Gold is an alloy that is formed after mixing the original yellow color gold with the metals like – palladium, nickel, copper that imparts it the white color or maybe grey or off-white. The white gold is coated with rhodium metal, and the purity of it depends upon the karat (18 or 24 karats) and the amount of the white gold used in making up the jewelry.  

Platinum is nearly about purified to up to 95%. The metal is somewhat mixed with other elements copper, nickel. The price range of the metal ranges as of with the purity of the metal and the amount of metal used in making up the jewelry. The platinum metals require extensive care and maintenance when worn.

What is White Gold?

White gold is not a naturally occurring metal and thus is obtained by the mixing of two or metals with the original yellow metal Au. The other metals that are commonly used for mixing or doping are nickel, palladium, copper. After doping, the metal has undergone a coating of rhodium which gives it a very bright lustrous white shine to the metal.

The purity standards of the metal depending on the different compositions that are – 18 karats of the gold contains a percentage of 75 gold within it while 24 karat of the gold contains a percentage of 58.3% gold within it along with the doped elements like copper, nickel, palladium. The price for the same also varies with the purity. The less is the karat. The less is the price of the jewelry or ornament.

As the metals contain doped elements in high percentages, therefore, it has a high risk of allergies associated with it. The durability of the jewelry made with it is quite high and can be worn for daily purposes. The jewelry or ornaments maintenance requires dipping of them in the gold as with the time passes. The white color wears out into yellow that is the original color of the gold.

What is Platinum?

Platinum is a metal that is obtained very rarely in nature, and the natural color of the metal is white lustrous with a bright shine. The metal is much heavier and harder as compared with the metal gold. Because of its heaviness as its property, platinum is quite easy for jewelry makers to use in its purest form. Also, the rare occurrence of the metal makes it more expensive.

The purest form of the metals contains 95% of it. Some of it is mixed with copper or nickel. The durability of the metal is very good compared to that of gold as it is heavier. Also, the metal is scratch-proof, but it gets some ridges on the surface because of use in daily purposes, which is known with a specific term called ‘the patina of age,’ which symbolizes the love, affection, ad uniqueness of the jewelry for their heirloom.

Main Differences Between White Gold and Platinum

  1. The composition of the white gold for different purity standards varies according to it for 18 karats white gold, the amount of gold is 75% while for the 24-karat white gold, it has 58.3% of gold all mixed with different metals that are – palladium, nickel, copper whereas comparatively on the other side, the composition of the platinum metal is 95% with 5% minimum doping of the other elements with it. 
  2. The price of white gold is way lower and pocket-friendly, whereas comparatively, on the other hand, the price of platinum is about 40%-50% higher than that of gold. 
  3. The appearance of the ornaments or jewelry formed by white gold appears to be in white/off-white/grey, which gates pale with overtime and comes to the original color of yellow whereas comparatively, on the other hand, the color or the appearance of the ornaments or jewelry of the platinum is pure white as it is naturally occurring.
  4. Ornaments or jewelry made of white gold is supposed to be with high durability and are often used for everyday purpose while comparatively, on the other hand, the ornaments of jewelry made out of platinum is highly durable than that of gold as it is a heavier metal.
  5. White gold requires twice or thrice a year after dipping in gold for its maintenance and care, whereas comparatively, on the other hand, platinum requires more often the repolishing and replating of the ornament or jewelry.
  6. The percentage of the mixture of elements in the white gold composition may lead to a high possibility of allergic reactions when worn by someone, which can be minor to severe depending on the causality, whereas comparatively, on the other hand, the percentage of doped elements in Platinum is quite very low thus it is known to be having less hypoallergenic metal potential.
  7. White gold is formed after the mixture of two or more metals with different compositions in nature, as it is not a naturally occurring metal, whereas comparatively, on the other hand, platinum is the naturally occurring metal almost in its purest form and is very rare.   

Conclusion

The different ornaments and jewelry with different shapes and designs require different metals to be used. The different metals like – silver, gold (yellow gold, white gold, rose gold), platinum are widely used for making pieces of jewelry and ornaments. The two white gold and platinum are way different from each other, not with a single difference but with many of the important factors. These may include the purity and amount of the composition of the respective metals, pricing, their durability, potential of not being allergic, natural color, the maintenance required for it. However, the occurrence of gold is not as rare as it is considered to be for platinum metal.
