Difference Between White Gold and Silver

White gold and silver may look very similar and are often used making precious jewelry such as necklaces and wedding bands. Both of these need to be polished regularly to prevent tarnishing. For most people, it is difficult to tell which one is which with the naked eye. White gold is usually coated with rhodium, manganese, palladium, or nickel which is a kind of white metal that enhances strength and luminescence. As for silver, it is often combined with copper to give off that similar sparkling white look.

 

What is White Gold?

Gold came from the Latin word “aurum” and white gold is an alloy (combination of metals) which shines like a mirror due to its white metal plating. The usual combination is 90% gold and 10% nickel. In the jewel industry, it is often loosely referring to any gold alloy with a whitish hue. Thus, it covers a range of colors from pale rose to pale yellow. Rhodium plating is also usually used to give off that silvery glow shown in advertisements.

Gold jewelry is marked with karats or gold purity. For instance, 18k is 75% pure and 14k is 58% pure. The following table features the most common mixes in producing white gold:

PERCENTAGE OF:
Type Gold Nickel  Copper Zinc Silver  Palladium 
14k White gold with Nickel 58.3 11 23 7.7
18k White gold with Nickel 75 8 10 4.5 2.5
14kt White Gold with Palladium 58.33 32.17 9.5
18 kt White Gold with Palladium 75 25

 

What is Silver?

Silver came from the Latin term “argentum” which means “white” or “shiny”. It is a pure chemical element and has the highest reflectivity as well as thermal and electrical conductivity as compared to any pure metal. Native silver, which is the pure elemental form and found in the earth’s crust, occurs at 0.08 parts per million. Silver is most often formed as a byproduct of refining gold, zinc, lead, and copper.

Regarding its marking, the purity of silver is specified. For instance, a “925” indication is present in sterling silver jewelry. The following table shows the most common mixtures:

PERCENTAGE OF:
Type Silver Trace Elements Nickel  Copper Germanium  Brass
Fine Silver 99.99 0.01
Sterling Silver 92.5 7.5 (if not Copper) 7.5 (if not Nickel)
Argentium and Non-tarnish Alloy 92.5 5.5 (may vary) 2 (may vary)
Coin Silver  90 10
Silver-Filled 5-10 90-95
