How to Tell If Pearls Are Real | A Simple Buyer’s Guide
Pearl jewellery has a timeless beauty that never goes out of style. Whether you’re buying a pearl necklace as a meaningful gift, choosing wedding day jewellery, or investing in a piece for everyday wear, one question often comes up first: how do you know if pearls are real?
With imitation pearls widely available, it’s completely natural to want reassurance before buying. In this guide, we’ll explain how to tell if pearls are real, the simple tests you can try at home, and why genuine freshwater pearls are such a special choice for jewellery.
Why It’s Important to Know If Pearls Are Real
Real pearls are formed naturally inside molluscs and have unique characteristics that cannot be perfectly replicated. Genuine pearl jewellery is not only more beautiful but also longer lasting, more valuable, and often hand-knotted for durability.
If you’re investing in handmade pearl jewellery, knowing the difference between real pearls and imitation pearls helps you buy with confidence and care for your jewellery correctly.
How Are Real Pearls Formed?
Unlike gemstones that are mined and cut, pearls are created by living organisms. When a tiny irritant enters a mollusc, such as an oyster or freshwater mussel, it coats the irritant in layers of nacre. Over time, these layers build up to form a pearl.
Freshwater pearls, commonly used in handmade jewellery, are grown in mussels and are prized for their soft lustre, natural shapes, and beautiful range of creamy white tones.
How to Tell If Pearls Are Real: 6 Simple Tests
1. The Tooth Test (The Most Well-Known Test)
Gently rub the pearl across the edge of your tooth.
Real pearls feel slightly gritty or sandy due to the layers of nacre.
Imitation pearls feel smooth, slippery and glass-like.
This is a great and surprisingly effective way to test pearls at home.
2. Look at the Surface
Examine the pearl closely.
Real pearls have tiny natural imperfections, subtle ridges, or variations.
Fake pearls often look too perfect, with an overly smooth or plastic-like finish.
Natural beauty is one of the reasons pearl jewellery feels so special — no two pearls are ever exactly the same.
3. Check the Lustre
Real pearls reflect light in a soft, deep way.
Genuine pearls have a warm, glowing lustre that seems to come from within.
Imitation pearls tend to reflect light sharply and look shiny rather than luminous.
4. Weight Test
Hold the pearl or piece of jewellery in your hand.
Real pearls feel surprisingly heavy for their size.
Fake pearls are usually lightweight, especially plastic versions.
5. Drill Hole Test (If Visible)
Look at the hole where the pearl has been drilled.
Real pearls show clean drill holes with visible layers of nacre.
Fake pearls may show chipped coating or peeling around the hole.
This is especially useful when examining pearl necklaces or bracelets.
6. Temperature Test
When first touched, real pearls feel cool and warm up gradually.
Imitation pearls tend to feel room temperature immediately.

Are Freshwater Pearls Real Pearls?
Yes — freshwater pearls are 100% real pearls.
They are grown in freshwater mussels and consist almost entirely of nacre, which gives them excellent durability and a beautiful, soft glow. Freshwater pearls are a popular choice for handmade pearl jewellery because they are strong, versatile, and perfect for everyday wear as well as special occasions.

Why Real Pearls Are Hand-Knotted
If pearls are genuine, they should be hand-knotted between each pearl.
Hand-knotting:
Prevents pearls from rubbing against each other
Stops dirt from entering the drill holes
Gives the necklace or bracelet a beautiful, fluid movement
Adds longevity to your jewellery
Hand-knotting is a sign of quality craftsmanship and care, however graduated pearl necklaces do not tend to be knotted as the design will give the pearl a fluid movement. You can have your pearls restrung through our professional pearl restringing service at Watermeadow Lane Jewellery.
Why Pearls Are So Popular for Wedding Jewellery
Pearls have long been associated with love, purity, and new beginnings, which is why they are traditionally worn on wedding days.
Brides often choose pearl jewellery because:
It complements wedding dresses beautifully
It feels soft, romantic, and timeless
It photographs elegantly
It can be worn again long after the wedding day
Whether worn as a pearl necklace, earrings, or a complete pearl jewellery set, real pearls bring understated elegance to wedding day jewellery. You can also have your inherited pearls restrung or redesigned so they can be worn again and again and passed down through the family.
Caring for Real Pearl Jewellery
Because pearls are organic gemstones, they need gentle care.
To keep pearl jewellery looking its best:
- Put pearls on after perfume and hairspray
- Wipe gently with a soft cloth after wearing
- Store flat, away from other jewellery
- Have pearls professionally restrung every few years if worn often
Proper care ensures your pearl jewellery lasts for many years.
Final Thoughts: Buying Pearl Jewellery With Confidence
Knowing how to tell if pearls are real allows you to shop with confidence and appreciate the beauty of genuine pearls. From the tooth test to examining lustre and surface texture, real pearls have unmistakable qualities that imitation pearls simply can’t replicate.
If you’re choosing pearl jewellery as a gift, for a wedding, or as a timeless addition to your collection, genuine freshwater pearls offer beauty, meaning, and longevity — making them a truly special choice.
