What Is Pearl Luster? (#PearlLuster #PearlValue)
Luster is a key factor in determining pearl quality, influencing the unique beauty of both natural and cultured pearls. Many experts consider luster to be the most important characteristic when evaluating pearls.
How to Identify High Luster Pearls (#HighLusterPearls)
- High-luster pearls display sharp, bright reflections on their surface.
- Luster varies by pearl type, with some Japanese saltwater pearls having an almost metallic luster due to their highly reflective surface (Courtesy of K. Otsuki Pearl Co., Ltd.).
- Baroque pearls can be more difficult to evaluate, as their irregular surfaces affect reflection clarity.
Luster Grading Scale
When all other value factors are equal, higher luster pearls are more valuable. Here’s a breakdown of pearl luster grades:
🔹 Excellent – Reflections are bright and sharp
🔹 Very Good – Reflections are bright and near sharp
🔹 Good – Reflections are bright but slightly hazy around the edges
🔹 Fair – Reflections are weak and blurred
🔹 Poor – Reflections are dim and diffused
For buyers and collectors, prioritizing high-luster pearls ensures maximum beauty and investment value in freshwater, Akoya, South Sea, and Tahitian pearls.
