1. Introduction to Hypoallergenic Jewelry

1.1 Understanding Metal Allergies in Jewelry

Metal allergies affect approximately 10-20% of the population, with nickel being the most common irritant. Symptoms include:

• Redness and itching

• Skin rashes (contact dermatitis)

• Blistering in severe cases

1.2 Why Rose Gold-Plated Pearl Earrings?

Rose gold plating offers:

• Warm, flattering pink hue

• Copper content naturally resists corrosion

• Less likely to contain nickel than white gold

Pearls provide:

• Classic elegance

• Non-metallic contact points (reducing allergy risk)

1.3 JINGYING’s Expertise in Hypoallergenic Jewelry

Specialized processes include:

• Nickel-free base metals

• Medical-grade plating techniques

• Independent allergy testing

2.2 Rose Gold Plating Composition

• 18K Rose Gold: 75% gold, 22.25% copper, 2.75% silver

• 14K Rose Gold: 58.3% gold, higher copper content

• Copper-rich formula naturally resists nickel contamination

2.3 Pearl Quality Considerations

• Freshwater vs. Saltwater pearls

• Drilled pearl coating to prevent metal contact

• Adhesive options for sensitive skin
