Choosing Your Shine: Understanding the Differences Between 14K, 18K Gold, and Platinum Jewelry

Understanding Jewelry Metal Purity

Gold Purity: 18K vs 14K

Gold's purity is measured in karats (K), which denotes the amount of gold out of 24 parts. Pure gold is 24K but too soft for most jewelry, hence the creation of stronger alloys.

18K Gold
Consisting of 75% gold, with the remainder made up of metals like silver and copper, 18K gold offers a richer yellow tone and a good balance of purity and durability.
14K Gold
Contains 58.3% pure gold. It's more durable than 18K due to a higher percentage of alloy metals mix, making it an excellent choice and a preference for everyday wear.



Unlike gold, platinum used in jewelry is typically 95% pure, alloyed with metals like cobalt or iridium. It's highly durable, making it ideal for settings that secure precious stones firmly in place.

Precious Metal Characteristics

Gold: The color and properties of gold vary depending on the alloy. It is naturally resistant to rust, tarnish, and corrosion.

Platinum: Platinum is denser and more durable than gold, and it maintains its white sheen without the need for plating, unlike white gold.

Pros and Cons of Choosing Between 14K, 18K Gold, and Platinum

 Pros Cons

14K Gold

Highly durable, more affordable, and holds up better against wear and tear. Less vivid color due to lower gold content.
18K Gold Higher purity, richer color, and retains value better over time. Softer and more prone to scratching, higher price point.
Platinum Extremely durable, does not fade or tarnish, and hypoallergenic. More expensive and heavier, which might not be comfortable for all wearers.

Technical Breakdown of Gold Color Chart

Gold jewelry comes in various colors, each achieved by altering the alloy composition:


White Gold:

Achieved by mixing gold with palladium or nickel, and silver, often coated with rhodium for durability and a whiter appearance. Typically, for 18K white gold, the alloy is about 75% gold and 25% white metals.


Rose Gold:

This pink-toned gold contains a higher proportion of copper, usually around 25% when alloyed with 75% gold, giving it a warm, rosy hue.


Yellow Gold:

The classic gold color is usually created from a mix of 50% gold and 50% copper and silver, maintaining a balance that preserves the metal’s yellow hue.
