Pearls have a quiet, timeless appeal that suits Singapore life, from office wear to weddings, Chinese New Year visiting and evening dinners. But walk into a jeweller and the range is confusing: strands that look similar can differ enormously in price, and terms like “AAA”, “nacre” and “lustre” are thrown around freely. This guide to pearl jewellery Singapore shoppers can actually use explains the main pearl types, how quality is judged, what to ask before you buy, and how to look after pearls in a hot, humid climate.
Natural, Cultured and Imitation Pearls
Before comparing types, it helps to understand where pearls come from.
- Natural pearls form without human help when an irritant gets inside a mollusc and layers of nacre build up around it. They are extremely rare today and mostly seen in antique pieces and auctions.
- Cultured pearls are grown by people who place a nucleus or a piece of tissue inside an oyster or mussel, which then coats it with nacre over months or years. Almost every pearl sold in shops today is cultured. Cultured does not mean fake; it is a real pearl grown with assistance.
- Imitation pearls are glass, shell or plastic beads coated to look like pearls. They are fine for costume jewellery but should be priced and labelled as such.
A simple, widely used home check is the tooth test: real pearls usually feel slightly gritty when gently rubbed against the edge of a tooth, while imitations tend to feel smooth. It is not a substitute for a professional assessment, but it can flag an obvious imitation.
The Main Pearl Types Compared
Most cultured pearls you will see fall into four families. Each has a distinct look, typical size range and price position.
| Pearl type | Where it is grown | Typical look | Price position |
|---|---|---|---|
| Freshwater | Mussels in lakes and rivers, mainly China | Wide range of shapes and soft colours (white, pink, lavender); often all nacre | Most affordable; great for everyday pieces |
| Akoya | Akoya oysters, traditionally Japan, also China | Round, smaller, very sharp mirror-like lustre, white with rosé or silver overtones | Mid to high; the classic strand look |
| Tahitian | Black-lipped oysters in French Polynesia | Naturally dark: grey, green, peacock and aubergine tones | High; bold statement pieces |
| South Sea | Large oysters in Australian, Indonesian and Philippine waters | The largest pearls, white, silver or golden, with a soft satiny glow | Highest; heirloom and occasion jewellery |
Freshwater pearls have improved a great deal in recent decades, and good ones can look very close to Akoya at a lower cost. South Sea pearls, particularly the golden ones from Indonesian and Philippine waters, are especially popular in the region for weddings and milestone gifts.
How Pearl Quality Is Graded
There is no single universal grading system. Many sellers use an A to AAA scale, others use letter or number systems, and the same label can mean different things at different shops. Instead of relying on a grade alone, judge the factors that labs and experienced jewellers look at:
- Lustre. The single most important factor. Good lustre gives sharp, bright reflections; you should be able to see your face or a light source clearly. Poor lustre looks chalky or dull.
- Surface. Look for spots, pits, bumps or wrinkles. A few small marks are normal in cultured pearls, but they should not catch your eye at arm’s length.
- Shape. Round pearls are the most sought after. Near-round, oval, drop, button and baroque (irregular) shapes cost less and can be very attractive, especially in modern designs.
- Colour. This includes body colour (white, cream, gold, black) plus overtone, the subtle sheen of pink, green or silver on top. Choose what flatters your skin tone.
- Size. Measured in millimetres. Bigger generally means pricier within the same type.
- Nacre thickness. For Akoya and saltwater pearls with a bead nucleus, thicker nacre means better lustre and durability. Thin nacre can chip or wear through over time.
- Matching. On a strand or a pair of earrings, pearls should match in size, colour and lustre.
What to Ask Before Buying Pearl Jewellery
Whether you are shopping in a mall jeweller, an independent workshop or online, a few questions protect you:
- Which pearl type is it, and is it cultured or imitation? A reputable seller will answer clearly.
- Is any treatment involved? Many pearls are bleached, polished or dyed. Treatments are common, but they should be disclosed, especially for unusual colours.
- Is the strand knotted? Good necklaces have a small knot between each pearl so they do not rub together and, if the thread breaks, you lose only one pearl.
- What metal is used for clasps and settings? Check whether it is solid gold, gold-plated silver or another alloy, as this affects price and wear.
- Is there a certificate or written description? For higher-value pieces, ask for documentation of type, size and any treatments.
- What is the returns and restringing policy? Find out whether the shop offers restringing and what happens if a pearl comes loose.

Caring for Pearls in Singapore’s Humidity
Pearls are organic gems and are much softer than diamonds or sapphires. Heat, sweat, chemicals and moisture all affect them, which makes care particularly important here.
- Last on, first off. Put pearls on after perfume, hairspray, sunscreen and makeup, and take them off before washing your face or showering. These products can dull the surface.
- Wipe after wearing. Use a soft, slightly damp cloth to remove sweat and oils, then let pearls air dry flat before storing. Sweat is acidic, and Singapore days produce plenty of it.
- Never use ultrasonic cleaners or harsh chemicals. These can damage nacre and loosen drill holes.
- Store separately and flat. Keep pearls in a soft pouch or a fabric-lined box, away from harder gems that can scratch them. Hanging a strand can stretch the silk thread over time.
- Avoid sealed plastic bags. Pearls need a little moisture to avoid drying out, but stagnant damp air can affect the silk thread. A breathable pouch in a drawer in an air-conditioned room is ideal.
- Skip the pool and the gym. Chlorine, saltwater and sweat-heavy workouts are hard on pearls.
- Restring periodically. Silk thread stretches and weakens, especially with frequent wear in humid weather. Many jewellers suggest checking strands regularly and restringing when you see gaps between knots or a fraying thread.
Choosing the Right Pearls for You
A simple way to narrow the choice:
- Everyday studs or a first strand: good freshwater pearls give the most value.
- Classic office or formal strand: Akoya pearls deliver that crisp, bright look.
- Statement or evening piece: Tahitian pearls bring dramatic dark tones.
- Wedding, milestone or heirloom gift: South Sea pearls offer size and presence.
Whatever you choose, buy from a seller who explains type, treatment and quality openly, and care for the pieces properly. Looked after well, pearls can be worn for decades and passed down.
