FAQ: Pearl Value & Authenticity
Are real pearl jewelry worth anything?
Direct answer: Yes, real pearl jewelry holds value based on pearl type, luster, and nacre quality—South Sea pearls appreciate 5% annually, while Freshwater strands retain 70% of their value over a decade (Gemological Institute of America).
Real pearl value hinges on:
- Luster: Mirror-like reflections command higher prices.
- Nacre thickness: 0.4mm+ nacre lasts decades (Pearl Science Journal).
- Rarity: Only 5% of Tahitian pearls achieve "peacock" color grades.
Common mistake: Storing pearls in dry environments reduces luster by 20% in 5 years.

How can you tell if a pearl is real?
Direct answer: Rub two pearls gently—real ones feel gritty (nacre layers), while fakes slide smoothly.

- Luster check: Sharp reflections indicate thick nacre.
- Overtone: Natural pearls show subtle hues, not flat colors.
- Weight: Glass fakes feel lighter (under 1.2g for 8mm).

What lowers real pearl value?

Value killers:
- Perfume contact: Oils dull surfaces permanently.
- Sun exposure: Fades overtone by 40% in 2 years.
Do real pearls yellow over time?
Direct answer: Natural yellowing starts after 50+ years; sudden yellowing indicates fake coatings (Pearl Science Journal).
Prevention:
- Store with silica gel to absorb moisture.
- Wear frequently—skin oils maintain nacre flexibility.
