Surface of Pearls - A Guide to Smoothness
Share
When it comes to evaluating the quality of a pearl, one of the most important factors to consider is its surface quality. The surface quality of a pearl refers to the presence or absence of imperfections, such as blemishes, scratches, or pits, on the surface of the pearl. In this blog, we'll explore the four main grading levels of surface quality in pearls: clean, minor, noticeable, and blemish. We'll compare these levels in terms of appearance, value, and rarity.
Clean: The Highest Grading Level
A clean pearl is one that has no imperfections on its surface. This is the highest grading level for surface quality, and it's extremely rare to find a pearl that meets this standard.
- Appearance: Flawless, smooth surface
- Value: Extremely high, due to its rarity
- Rarity: Extremely rare, less than 1% of pearls meet this standard
Minor: A Small Imperfection
A minor pearl is one that has a small imperfection on its surface, such as a tiny scratch or pit. This imperfection is barely noticeable and does not detract from the overall appearance of the pearl.
- Appearance: Small imperfection, barely noticeable
- Value: High, but slightly lower than clean pearls
- Rarity: Rare, around 5% of pearls meet this standard
Noticeable: A More Obvious Imperfection
A noticeable pearl is one that has a more obvious imperfection on its surface, such as a larger scratch or pit. This imperfection is noticeable, but it does not dominate the appearance of the pearl.
- Appearance: More obvious imperfection, noticeable but not dominant
- Value: Medium, lower than minor pearls
- Rarity: Common, around 20% of pearls meet this standard
Blemish: A Significant Imperfection
A blemish pearl is one that has a significant imperfection on its surface, such as a large scratch or pit. This imperfection dominates the appearance of the pearl and can affect its value.
- Appearance: Significant imperfection, dominates the appearance
- Value: Low, due to its imperfection
- Rarity: Common, around 50% of pearls meet this standard
