At Beldad Jewelry, we exclusively use 18k gold to ensure the perfect balance between lasting luxury and everyday durability.

• Purity & Quality: Composed of 75% pure gold, our 18k gold pieces offer a richer, deeper color compared to 10k or 14k gold.

  
  

• Skin Friendly: High-purity 18k gold is naturally hypoallergenic, making it ideal for those with sensitive skin.

  
  

• Timeless Value: Unlike gold-plated or gold-filled jewelry, our solid 18k gold pieces will not tarnish or wear away over time, retaining their intrinsic value for generations.

• Crafted for Life: Designed to be worn and cherished, 18k gold is resistant to daily wear while remaining soft enough to be intricately detailed by our master jewelers in Yamanashi.

Our 18k gold is designed to last a lifetime. To maintain its signature brilliance:

• Cleaning: Gently wipe with a soft, lint-free cloth after wearing.

• Storage: Store in your signature Beldad box to prevent scratches.

• Protection: Remove before swimming or using harsh chemicals.
