Buying a Pearl Necklace: Freshwater, Akoya or South Sea – Which One Suits You?

Buying a pearl necklace is no longer a straightforward decision – the market offers freshwater pearls from China for €50, Akoya pearls from Japan for €500, South Sea pearls from Australia for €5,000, and everything in between. What makes the difference? What really matters? And which pearl necklace offers the best value for your needs? This comprehensive buying guide provides all the answers.

The four major types of cultured pearls

Freshwater pearls – the best value for money

Origin: Mainly China (mussels in lakes and rivers)
Size: Typically 4–12 mm, outliers up to 16 mm
Colors: White, cream, pink, lavender, also treated in many colors
Shapes: Round, oval, baroque, button – greater variety of shapes than other types
Luster: Good to very good, but generally a little less brilliant than Akoya
Price for 45 cm necklace: €80–500 depending on quality

Freshwater pearls are the most democratic choice: beautiful, affordable, durable, and available in many quality levels. They are the ideal choice for everyday wear and as an introduction to pearl jewelry.

Akoya pearls – the classic pearl necklace

Origin: Japan and China (saltwater mussel Pinctada fucata)
Size: Typically 6–10 mm, very uniformly round
Colors: White to cream with pink or silver overtone
Luster: Excellent – the highest reflective sheen among all cultured pearls
Price for 45 cm necklace: €300–2,500 depending on size and quality

Akoya pearls are the image most people have in mind when they think "pearl necklace". Their exceptional roundness and mirror-like high luster are unparalleled. The classic bridal and festive necklace.

Tahitian pearls – the dramatic alternative

Origin: French Polynesia (black-lipped oyster Pinctada margaritifera)
Size: Typically 8–16 mm
Colors: Dark gray to black, with overtones of green, peacock blue, aubergine
Luster: Excellent – the dark base with colorful reflections is unique
Price for 45 cm necklace: €800–8,000 depending on quality and matching

Tahitian pearls are the opposite of the classic white pearl necklace. Dark, dramatic, expressive. A black pearl necklace is one of the most impressive pieces of jewelry available.

South Sea pearls – the queen of all pearls

Origin: Australia, Indonesia, Myanmar (gold-lipped oyster Pinctada maxima)
Size: 10–20 mm – the largest cultured pearls in the world
Colors: White-silver to golden yellow
Luster: Exceptionally silky-smooth and deep
Price for 45 cm necklace: €3,000–50,000+

South Sea pearls are the luxury of the pearl world – rare, large, of unsurpassed quality. For collectors and as investment jewelry.

Pearl necklace quality criteria: What really matters

Luster – the most important feature

Luster describes how deep and reflective a pearl shines. A pearl with high luster will show your reflection – milky, dull pearls have low luster. Luster is the quality characteristic with the strongest influence on value.

Surface

High-quality pearls have a smooth, flawless surface. Slight natural irregularities (small spots, minimal bumps) are normal for genuine cultured pearls and not a defect if they are small.

Matching

In a pearl necklace, all pearls must be as similar as possible: same size (tolerance max. ±0.5 mm), same color, same luster. Professionally "matched" necklaces are more expensive but significantly more beautiful than unmatched ones.

Nacre thickness

The thicker the nacre, the deeper the luster and the more durable the pearl. Standard value: min. 0.4 mm for good quality; 0.8–1.5 mm for very good quality.

Pearl necklace lengths: What suits when?

• Collar (30–35 cm): Sits directly on the neck. Very elegant and old-fashioned in a positive sense.
• Choker (38–42 cm): Sits close to the neck. Modern and feminine.
• Princess (43–50 cm): The most popular length – rests on the collarbone.
• Matinee (50–60 cm): Rests on the chest. Classically elegant for business.
• Opera (70–90 cm): Long, can be worn doubled. Very opulent.

Caring for your pearl necklace

• Put on last – after perfume, hairspray, cosmetics
• Wipe with a soft, damp cloth after wearing
• No ultrasonic, no steam cleaner, no acids
• Do not store airtight – keep in a breathable fabric pouch
• Have the string re-strung by a jeweler every 1–2 years (pearls secured by knots)
