1. Understanding the Types of Pearls

Before evaluating pearl quality, it is important to understand the different types of pearls available.

Natural Pearls

Natural pearls are extremely rare and form without human intervention. Because of their rarity, they are highly valued by collectors.

Cultured Pearls

Cultured pearls are formed with human assistance, where an irritant is introduced into a mollusk. These pearls dominate the modern jewellery market.

Saltwater Cultured Pearls

• Akoya Pearls: Known for their near-perfect round shape and high lustre.
• South Sea Pearls: Large, luxurious pearls with thick nacre and satiny glow.
• Tahitian Pearls: Known for natural dark tones and rich overtones.

Freshwater Cultured Pearls

Freshwater pearls are grown in lakes and rivers and are known for their variety of shapes and colours. They offer accessibility and versatility.

To understand these in depth, refer to our types of pearls guide.

2. The 6 Major Factors for Evaluating Pearl Quality

When evaluating pearls, six key factors determine their beauty, durability, and value.

1. Luster

Luster is the most important factor. High-quality pearls have a bright, sharp reflection and deep inner glow.

2. Surface Quality

Pearls with fewer blemishes such as spots or pits are more valuable.

3. Nacre

Thick nacre enhances durability and luster and indicates longer formation time.

Larger pearls are rarer and generally more valuable. However, size must be balanced with luster and surface quality.

Round pearls are traditionally most valued, but baroque pearls are prized for their uniqueness.

Colour includes body colour and overtone. The best colour is one that complements your style.
