Silver, platinum, and white gold are considered “white” metals
when used for jewelry, although they are all silver in appearance. The three
metals may look similar, but they are very different in content. Sterling
silver is the least expensive of the three metals and is comprised of 92.5%
silver and 7.5% other metals. It is the softest of the three metals and
tarnishes over time, but with frequent and proper cleaning, it serves as an
alternative to platinum and white gold because of its lower price.
White gold is a harder metal than silver and is often used
for settings of precious stones. White gold is more durable than silver, it
does not tarnish, and it holds its shine very well. Like yellow gold, white
gold holds up fairly well over time under normal wear. However, it is
considerably more expensive than sterling silver and is typically reserved for
more elegant jewelry such as engagement and wedding rings.
Platinum is the “premium” white metal. It is the hardest and
most durable white metal and is often chosen for rings and ring settings by
people who appreciate the wear and tear to which hand jewelry can be exposed.
Platinum can take much more day-to-day abuse before needing to be repaired,
whereas silver and white gold need more care. Platinum’s durability and
longevity is reflected in its cost, however. A $20 sterling silver ring would
cost about $200 in white gold and the same ring might cost around $600 in
platinum.
