Pearl Grading Guide

Evaluating the Quality of Pearls

At Mood Pearl, we understand that selecting the perfect pearl jewelry can be a delightful yet challenging experience. To assist you in making an informed decision, we have established a comprehensive grading system based on four key criteria: luster, blemishes, roundness, and matching. Our grading scale prioritizes these factors in order of importance, with the highest grade being "A".

1. Luster

Priority Level: 1 (Most Important) Luster refers to the quality of light reflected from the pearl's surface. It is the most crucial factor in determining a pearl's beauty and value.

Grade A: Exceptional luster with sharp, bright reflections.

Grade B: Good luster with clear reflections.

Grade C: Fair luster with moderate reflections.

Grade D: Poor luster with weak reflections.

2. Blemishes

Priority Level: 2 Blemishes are surface imperfections on the pearl. The fewer the blemishes, the higher the quality.

Grade A: Very few or no blemishes, barely noticeable to the naked eye.

Grade B: Minor blemishes, not easily noticeable.

Grade C: Some visible blemishes, but do not significantly detract from the overall appearance.

Grade D: Obvious blemishes, affecting the pearl's appearance.

3. Roundness

Priority Level: 3 Roundness measures how perfectly spherical the pearl is. While round pearls are highly valued, other shapes also have their unique charm.

Grade A: Perfectly round.

Grade B: Near-round with slight deviations.

Grade C: Slightly off-round but still visually appealing.

Grade D: Noticeably off-round.

4. Matching

Priority Level: 4 Matching assesses how well pearls in a piece of jewelry complement each other in terms of size, shape, color, and luster. This is especially important for multi-pearl items like necklaces and bracelets.

Grade A: Excellent matching with consistent size, shape, color, and luster.

Grade B: Good matching with minor variations.

Grade C: Fair matching with noticeable variations.

Grade D: Poor matching with significant inconsistencies.
