Short answer: a real pearl necklace can be worth anything from under A$100 to tens of thousands of dollars. Most of the difference comes from the type of pearl (freshwater, Akoya, Tahitian or South Sea), followed by lustre, size, surface, shape and matching, and finally the clasp, construction and condition of the necklace.
This guide explains each factor, gives rough price ranges for each pearl type, and answers the most common questions about what pearls are worth.
Quick guide: what different pearl necklaces are worth
The table below gives very approximate retail ranges for a strand or necklace in Australia. Prices vary widely with quality, size, length and the retailer, so treat these as a starting point rather than a valuation.
| Pearl type | Where it's grown | Typical look | Rough necklace value (AUD) |
|---|---|---|---|
| Freshwater | Mostly China, in lakes and rivers | White, pink, peach and lavender; many shapes, including baroque | Under A$100 to around A$1,000+ |
| Akoya | Mainly Japan and China, in saltwater | Round, classic white with high shine | Around A$300 to A$5,000+ |
| Tahitian | French Polynesia | Naturally dark: grey, green, peacock | Around A$1,000 to A$10,000+ |
| South Sea | Australia, Indonesia and the Philippines | Large, white, silver or golden | Around A$2,000 to A$30,000+ |
| Natural (wild) pearls | Formed without human help; extremely rare | Varies | Can reach very high values at auction |
Fun fact for Australians: Broome in Western Australia is one of the world's best-known sources of South Sea pearls, which are among the largest and most valuable cultured pearls.

The six factors that decide a pearl necklace's value
1. Pearl type
As the table shows, pearl type sets the overall price range. Saltwater pearls (Akoya, Tahitian and South Sea) usually cost more than freshwater pearls, but quality varies within every category: an excellent freshwater strand can be worth more than a low-grade Akoya strand.
2. Lustre
Lustre is the way light reflects from the pearl's surface, and it's often considered the single most important quality factor. Strong, crisp reflections are valued far more than a dull or chalky look.
3. Size
Pearls are measured in millimetres. Larger pearls take longer to grow and are rarer, so price rises steeply with size when other factors are similar.
4. Surface quality
Small natural marks are normal. The fewer and less noticeable the blemishes, the higher the value.
5. Shape and matching
Perfectly round pearls are the most traditional and often the most expensive. Oval, drop and baroque (irregular) pearls usually cost less, although baroque pearls are increasingly loved for their individuality. In a strand, how well the pearls match in colour, lustre and size also affects value.
6. Clasp, construction and condition
A solid gold clasp, knotted silk stringing and good condition all add value. Worn stringing, damage or repairs can reduce it, and documented provenance can increase it.
How much are freshwater pearls worth?
Freshwater pearls are the most affordable real pearls, because each mussel can produce many pearls at once. That's what makes them perfect for everyday jewellery. Value still depends on quality: a strand with bright lustre, clean surfaces and well-matched pearls is worth considerably more than a dull, mixed strand. Larger round freshwater pearls with strong lustre can approach the look of more expensive pearl types.
How much is a single pearl worth?
A single loose freshwater pearl may be worth just a few dollars, while a large, high-quality South Sea pearl can be worth hundreds or even thousands of dollars on its own. The same six factors apply, with size and lustre usually making the biggest difference.
Cultured vs natural pearls
Almost all pearls sold today are cultured: real pearls grown by an oyster or mussel after a pearl farmer places a small nucleus or tissue inside it. Cultured pearls are genuine pearls, not fakes. Natural pearls form without human help and are extremely rare, which is why they are priced at a completely different level. Imitation pearls, by contrast, are made from glass, shell or plastic with a pearly coating.
How can I tell if a pearl necklace is real?
Start with clear information from the seller about the pearl type and materials. A few signs can help, but none is conclusive on its own:
- Surface variation: real pearls usually show tiny differences in shape, colour and surface; identical, perfectly uniform beads can suggest imitations.
- Weight and temperature: real pearls often feel slightly heavy for their size and cool to the touch at first.
- Drill holes: look closely around the hole; peeling or flaking coating can suggest an imitation.
We don't recommend rubbing pearls against your teeth or scratching them. These tests can damage the surface and don't tell you anything about quality or value. For a valuable piece, professional identification is the reliable route.
Getting a pearl necklace valued in Australia
If you have an heirloom or need a valuation for insurance, take it to a qualified, registered jewellery valuer. They can identify the pearl type, assess quality and provide a written valuation. An insurance valuation usually reflects replacement cost, which can be higher than what you would receive if you sold the necklace.
Do pearls increase in value?
Most cultured pearl jewellery is best bought to wear and enjoy rather than as an investment. Exceptional natural pearls and rare pieces with strong provenance can be the exception, but age alone doesn't make a pearl necklace valuable. A newer, well-matched strand may be worth more than an older necklace in poor condition.
Frequently asked questions
Are freshwater pearls real pearls?
Yes. Freshwater pearls are genuine cultured pearls grown in freshwater mussels. They are simply more abundant than saltwater pearls, which makes them more affordable.
Are cultured pearls fake?
No. Cultured pearls are real pearls grown by a living mollusc. "Cultured" only means that people helped start the process.
Why are some pearl necklaces so cheap?
Very low prices usually mean imitation pearls, or lower-grade freshwater pearls with weaker lustre and more blemishes. Check the product description for the pearl type.
What is a baroque pearl?
A baroque pearl has an irregular, organic shape. Every one is unique, which is why baroque pearls have become popular for modern, everyday jewellery.
How should I care for a pearl necklace?
Put pearls on last, after perfume and make-up, wipe them with a soft cloth after wearing, and store them separately so they don't get scratched. Read our guide on how to store pearl jewellery and our Jewellery Care Guide.

The bottom line
The value of a pearl necklace comes down to pearl type first, then lustre, size, surface, shape and matching, and finally the clasp, construction and condition. For everyday style, freshwater and baroque pearls offer real pearls at an accessible price. For a high-value heirloom, a professional valuation is the only reliable answer.
