Understanding Gold: Types, Carat Weights, and What to Know Before You Buy

When shopping for fine jewelry, gold is one of the most timeless and popular choices. But not all gold is created equal. From different types like yellow, white, and rose gold to various karat weights like 10K, 14K, and 18K, there’s a lot to know before selecting the perfect piece.

At Gruno’s Diamonds, we believe that an informed customer is a confident customer. In this edition of The Radiance Report, we’re breaking down the types and karat weights of gold to help you make the best decision for your next jewelry investment.

Types of Gold: Yellow, White, and Rose

Gold comes in several beautiful hues. The difference isn’t just color—it’s also about alloy composition, durability, and style preference.

Yellow Gold

Classic and rich, yellow gold is the purest in appearance. It's made by mixing pure gold with metals like silver and copper.

• Pros: Hypoallergenic, timeless aesthetic, warm tone that complements all skin tones.
• Popular in: Vintage-inspired pieces, traditional wedding bands, and statement designs.

White Gold

White gold has a sleek, modern look. It’s created by combining pure gold with white metals such as nickel, palladium, or silver, and is often rhodium-plated for extra shine.

• Pros: Elegant, pairs well with diamonds, modern aesthetic.
• Popular in: Engagement rings, fashion-forward styles, and everyday essentials.

Rose Gold

Blush-hued and romantic, rose gold gets its pink tone from a high copper content in the alloy blend.

• Pros: Unique, warm tone, complements both vintage and modern designs.
• Popular in: Fashion jewelry, bridal sets, and mixed-metal looks.

Understanding Gold Carat Weights: 10K, 14K, 18K, and 24K

The karat (K) of gold refers to the amount of pure gold in the alloy. The higher the karat, the more gold—and the softer and more valuable the piece.

24K Gold (99.9% Pure Gold)

• Highest purity of gold available.
• Not commonly used in jewelry due to its softness and tendency to scratch.
• Best for: Collectible coins, investment pieces, or cultural jewelry.
  
  

18K Gold (75% Pure Gold)

• Rich in gold content, yet durable enough for regular wear.
• Has a luxurious, vibrant color.
• Best for: High-end fine jewelry and engagement rings.
  
  

14K Gold (58.3% Pure Gold)

• The most popular gold carat for jewelry in the U.S.
• Offers a great balance of purity, durability, and affordability.
• Best for: Engagement rings, necklaces, bracelets, and daily wear.
  
  

10K Gold (41.7% Pure Gold)

• Most affordable and durable option.
• Slightly less warm in tone due to lower gold content.
• Best for: Budget-friendly jewelry, men's bands, or casual styles.

Which Gold Is Right for You?
