Introduction
Pearls have always carried a certain reputation. For some, they bring to mind old Hollywood glamour. For others, memories of their grandmother’s treasured strand carefully tucked away for “special occasions.” And yes — somewhere along the way, pearls unfairly became associated with the idea that they were too traditional, too formal, or reserved only for women like Wilma Flintstone.
But pearls have quietly reinvented themselves.
Today, pearls are being worn layered with denim and white tees, paired with oversized blazers, stacked alongside chunky gold chains, and styled by women who want their jewellery to feel effortless rather than expected. From vintage elegance to modern cool, pearls have become less about rules and more about personality.
We’ve seen everyone from Audrey Hepburn to Rihanna redefine what pearl jewellery can look like. Even fashion’s modern muses — like Anne Hathaway’s iconic Andy Sachs character in The Devil Wears Prada 2 — helped shift pearls away from “prim and proper” into something polished, confident and undeniably chic. Pearls are no longer reserved for high teas and family heirlooms; they’ve become everyday luxury.
And perhaps that’s what makes pearls so special. No two are ever exactly alike. They’re organic, imperfect in the most beautiful way, and full of character — much like the women who wear them.
This guide is designed to help you navigate the world of pearls with confidence — from understanding the different types of pearls and what affects their value, to choosing pieces that suit your personal style and lifestyle. Whether you’re drawn to classic elegance, contemporary styling, or somewhere in between, pearls have a way of becoming part of your story.
1. Understanding Pearl Types
Each pearl type carries its own personality, beauty, and rarity. From the crisp refinement of Akoya pearls to the bold luxury of South Sea pearls, understanding the differences can help you choose pearls that truly reflect your personal style and how you want to wear them.
While all pearls are formed within oysters or molluscs, the environment they grow in, the species producing them, and the time they spend cultivating beneath the water all influence their appearance, lustre, size, colour, and value.
Akoya Pearls
When most people picture a “traditional pearl necklace,” they’re usually imagining Akoya pearls. They are the elegant strand necklace, delicate pearl studs, or heirloom pieces passed through generations.
Originally popularised in Japan in the early 1900s, Akoya pearls quickly became synonymous with sophistication and refinement. They are often considered the “classic” pearl.
Cultivated primarily in Japan and China, Akoya pearls are renowned for their exceptional lustre and near-perfect round shape. What sets Akoya pearls apart is their incredibly reflective surface. High-quality Akoya pearls have a sharp, mirror-like lustre that reflects light beautifully, giving them a crisp and polished appearance. When comparing pearl types side by side, Akoya pearls tend to look brighter and more formal due to this high shine.
Akoya pearls are also admired for their subtle overtone colours. While they are most commonly associated with white pearls, many fine Akoya pearls display delicate rose or soft pinkish overtones, which give warmth and depth to the pearl. This slight blush tone is highly sought after and is often considered one of the hallmarks of beautiful Akoya pearls, particularly in traditional Japanese grading.
Akoya pearls are typically smaller than South Sea pearls, generally ranging between 5mm and 9mm, although larger sizes are considered increasingly rare and valuable. Their smaller size makes them incredibly versatile for everyday wear and layering.
Traditionally associated with classic elegance, Akoya pearls have experienced a modern revival in recent years. Today, they are being styled far beyond the traditional single-strand necklace. We’re seeing Akoya pearls paired with oversized blazers, layered with gold chains, worn casually with denim and white shirts, or incorporated into minimalist modern jewellery designs.
They remain one of the most popular choices for:
- Bridal jewellery
- First pearl purchases
- Classic pearl strands
- Everyday pearl studs and pendants
- Timeless heirloom pieces
For those wanting pearls that feel sophisticated, refined, and endlessly wearable, Akoya pearls are often the perfect place to begin.
South Sea Pearls
If Akoya pearls are refined elegance, South Sea pearls are unapologetic luxury!
Cultivated in the warm waters of Australia, Indonesia, and the Philippines, South Sea pearls are among the rarest and most valuable pearls in the world. They are produced by the large Pinctada maxima oyster, which allows them to grow significantly larger than other pearl varieties.
South Sea pearls are prized for their impressive size, thick nacre, and soft, luminous glow. Unlike the highly reflective lustre of Akoya pearls, South Sea pearls display a deeper, satiny radiance often described as an “inner glow.” Their beauty feels softer, richer, and more organic.
Typically ranging from 9mm to 16mm+, South Sea pearls make an unmistakable statement. Even a single South Sea pearl pendant can carry incredible presence and elegance.
White and silver South Sea pearls are highly prized for their clean, luminous appearance and understated elegance. Their natural tones range from bright white to soft silver, making them incredibly versatile and timeless.
Golden South Sea pearls are among the rarest and most valuable pearls in the world. Cultivated primarily in the Philippines and Indonesia, their rich natural colour ranges from soft champagne through to deep, luxurious gold. Their rarity, combined with their striking warmth and size, makes them especially sought after by collectors and clients looking for something truly exceptional.
One of the reasons South Sea pearls are so highly valued is the extraordinary time, risk, and environmental sensitivity involved in cultivating them. The Pinctada maxima oyster is incredibly delicate and highly reactive to changes in its environment. Water temperature, salinity, pollution levels, storms, and even shifts in ocean currents can all impact the health of the oysters and the quality of the pearls they produce.
Pearl farmers must constantly monitor ocean conditions, and in some cases, oysters need to be carefully relocated to cleaner or more stable waters to protect them. Cultivation is a slow and labour-intensive process, often taking several years before a pearl is ready to harvest. Even then, there is no guarantee of success — many oysters will not produce a gem-quality pearl at all.
This combination of rarity, size, lustre, and the immense effort required to cultivate them is what places South Sea pearls among the most luxurious and valuable pearls in the world.
South Sea pearls appeal to those looking for:
- Luxury statement jewellery
- Investment-worthy heirloom pieces
- Contemporary pearl styling
- Rare and collectible gems
- Larger, more dramatic pearls
They often suit clients who want pearls that feel less traditional and more fashion-forward, organic, and elevated.
Tahitian Pearls
Tahitian pearls are instantly recognisable for their naturally dark and exotic colours.
Cultivated primarily in French Polynesia, Tahitian pearls are produced by the black-lipped oyster and are famous for their incredible range of tones. Rather than being simply “black,” these pearls can display captivating overtones of peacock green, charcoal, silver, aubergine, blue, bronze, and deep olive.
No two Tahitian pearls are ever exactly alike, which makes them especially appealing to those wanting jewellery with individuality and character.
Tahitian pearls are generally larger than Akoya pearls and have a more contemporary, bold aesthetic. Their darker tones pair beautifully with both yellow and white gold and offer a striking alternative to traditional white pearls.
Because of their naturally unique colouring, Tahitian pearls often feel artistic, modern, and slightly unexpected — perfect for someone wanting pearls that stand apart from tradition while still retaining luxury and sophistication.
Freshwater Pearls
Freshwater pearls are among the most versatile and expressive pearl varieties, offering exceptional beauty across a wide spectrum of shapes, sizes, and soft natural tones. Traditionally cultivated in lakes and rivers, they have evolved significantly in modern pearl farming, with high-quality selections now rivaling more traditionally “luxury” pearl categories.
They are known for their soft lustre, organic charm, and ability to adapt beautifully to both contemporary and classic jewellery design.
Within freshwater pearls, there are several notable categories:
Classic Freshwater Pearls
These are the most widely recognised, often featuring soft white, cream, blush, and lavender tones. They are typically available in a range of shapes including near-round, oval, and baroque. Their appeal lies in their natural variation and accessibility.
High-Lustre Cultured Freshwater Pearls
Modern cultivation techniques have produced freshwater pearls with significantly improved lustre and near-perfect roundness. These pearls offer a more refined, high-end finish while retaining the organic softness freshwater pearls are known for.
Large Round Freshwater Pearls (often referred to as Edison pearls)
Among the most prized freshwater varieties, these pearls are notable for their impressive size, strong roundness, and metallic-like lustre. They are typically cultivated using advanced nucleation techniques, resulting in pearls that closely resemble the aesthetic of saltwater South Sea pearls in size and lustre, but in a more affordable option. Their tones can range from bright white to soft gold and subtle pastel overtones, depending on growing conditions.
Baroque Freshwater Pearls
Celebrated for their individuality, baroque pearls embrace irregular shapes and sculptural forms. Each piece is entirely unique, making them popular in modern, artistic, and fashion-forward jewellery design.
2. What Determines Value?
Pearl value is defined by a combination of natural beauty and rarity.
Size
Size is one of the most immediate and influential indicators of a pearl’s rarity, desirability, and value. While beauty is never defined by size alone, larger pearls are significantly rarer in nature and therefore command a higher position in fine jewellery.
Pearl growth is a slow, organic process. Each additional millimetre represents years of formation within the mollusc, making larger pearls increasingly uncommon and more valuable as size increases.
How size impacts value
Pearl pricing does not increase in a linear way — it increases exponentially. A 1–2mm difference in diameter can represent a substantial jump in rarity, especially in high-quality saltwater pearls.
For example:
- A 6–7mm Akoya pearl is considered standard luxury grade
- An 8–9mm Akoya pearl is significantly rarer and more valuable
- A 10–12mm pearl begins to enter statement-level territory
- 12–16mm+ South Sea or Tahitian pearls are considered investment-grade luxury pieces
Size by pearl type
- Akoya pearls: typically 6–9mm, prized for perfect symmetry and high lustre rather than scale
- Freshwater pearls: range widely from 6–14mm+, with large high-quality rounds becoming increasingly desirable in modern luxury design
- Tahitian pearls: generally 9–14mm, with larger specimens showing stronger rarity and presence
- South Sea pearls: typically 10–16mm+, with the largest pearls being exceptionally rare and highly collectible
Size and luxury perception
In fine jewellery, size contributes to presence and impact. Larger pearls naturally draw attention due to their surface area, glow, and visual weight when worn.
However, true luxury is defined by balance — a large pearl without lustre or surface quality will never surpass a smaller pearl of exceptional quality.
The most valuable pearls combine:
- Generous size
- Strong, mirror-like lustre
- Clean surface quality
- Rare natural colour or overtone
Matching and rarity factor
When pearls are used in pairs (such as earrings), value increases further due to the rarity of finding two pearls that match perfectly in size, shape, colour, and lustre. The larger the matched pair, the rarer and more valuable the set becomes.
Lustre
Lustre is the most important quality factor. It refers to how light reflects from the pearl’s surface. High-lustre pearls appear sharp, reflective, and almost glowing from within.
Surface Quality
The fewer blemishes or imperfections, the higher the value. However, natural pearls may still display slight variations that confirm authenticity.
Shape
Perfectly round pearls are the rarest and most traditional. Baroque (irregular) shapes are increasingly popular in contemporary design for their individuality.
Colour
Colour is determined by the oyster type and natural environment. In luxury pearls, depth and richness of tone are often more valuable than brightness alone.
3. Most Valuable Characteristics
While beauty is subjective, the market consistently values:
- Large South Sea pearls with rich golden tones
- Tahitian pearls with strong peacock overtones
- Akoya pearls with exceptional lustre and symmetry
Ultimately, lustre remains the defining feature of a truly exceptional pearl.
4. How to Choose the Right Pearl for You
When selecting pearls, consider:
- Your personal style: classic, modern, or statement
- Skin tone and metal pairing (gold vs white gold)
- Occasion: everyday wear vs heirloom investment piece
- Whether you prefer symmetry or organic individuality
At Leskes Jewellers, we often say: the right pearl should feel like it was always meant to be yours.
5. Caring for Your Pearls
Pearls are organic gemstones, formed by nature rather than cut from stone — which means they require thoughtful, gentle care to preserve their natural lustre and longevity.
At Leskes Jewellers, we believe pearls should be worn and enjoyed, but treated with the same respect given to any fine heirloom.
How to wear your pearls
- Always put pearls on last when dressing and remove them first when undressing
- Avoid direct contact with perfumes, hairsprays, makeup, and lotions, as these can dull the surface over time
- Remove pearls before swimming, showering, or exercising, as chlorine, salt water, and perspiration can damage the nacre
Everyday care
- Wipe pearls gently with a soft, slightly damp cloth after wearing to remove natural oils and residue
- Avoid abrasive fabrics or jewellery cleaners, as these can scratch the delicate surface
- Do not use ultrasonic or steam cleaners — pearls are too delicate for these methods
Storage
- Store pearls separately from other jewellery to prevent scratching
- Use a soft pouch or lined jewellery box for protection
- Keep in a slightly breathable environment — pearls benefit from natural humidity and should not be stored in completely airtight conditions for long periods
Restringing and maintenance
- Pearl strands are traditionally strung on silk thread, which naturally stretches and weakens over time
- We recommend professional restringing every 1–2 years for regularly worn pieces
- Periodic inspection ensures clasps, knots, and settings remain secure
Long-term beauty
Unlike many gemstones, pearls actually benefit from being worn. The natural oils from the skin help maintain their lustre and prevent them from drying out, enhancing their glow over time.
For treasured heirloom pieces, we recommend occasional professional cleaning and inspection to ensure they remain as beautiful as the day they were created.
Final Thoughts
Buying pearls is deeply personal. Whether you’re choosing your very first pearl piece, investing in a future heirloom, celebrating a milestone, or searching for something modern and effortlessly wearable, pearls have a unique way of becoming part of your story.
Understanding the differences between pearl varieties, lustre, colour, size, shape, and quality helps you buy with confidence — but it’s equally important to choose pearls that feel right for you. The most beautiful pearls are not always the largest or the rarest; they’re the ones that suit your style, your lifestyle, and the way you want to wear them.
At Leskes Jewellers, we believe buying pearls should feel exciting, personal, and never overwhelming. We carefully hand-select every pearl for its beauty, lustre, colour, quality, and overall balance, helping guide our clients toward pieces that not only look exceptional, but feel meaningful to wear.
Whether you’re searching for timeless Akoya pearls, luxurious South Sea pearls, or something more contemporary and unique, we work closely with you to find the right combination of quality, size, style, and budget — ensuring you invest in pearls you’ll truly love for years to come.
Because pearls are never simply jewellery. They become memories, milestones, heirlooms, and pieces that are worn, treasured, and passed on.
Pearl Glossary & Definitions
Nacre
The smooth, iridescent substance layered by the oyster or mollusc to form a pearl. High-quality nacre gives pearls their beautiful glow, durability, and depth of colour.
Lustre
The shine and reflection seen on the surface of a pearl. Pearls with high lustre appear bright, sharp, and almost mirror-like, while lower lustre pearls can look soft or chalky.
Mabe Pearl
A half-pearl that grows attached to the inside shell of the mollusc rather than freely within it. Mabe pearls are often used in earrings, pendants, and statement jewellery because of their larger dome shape.
South Sea Pearl
A luxurious cultured pearl primarily grown in Australia, Indonesia, and the Philippines. Known for their large size, satin lustre, and white, silver, or golden tones.
Akoya Pearl
A classic cultured pearl traditionally associated with timeless pearl strands. Akoya pearls are known for their perfectly round shape and high reflective lustre.

Seed Pearl
Very small pearls traditionally used in antique and vintage jewellery designs, often set closely together in intricate patterns.
Pearl Nucleus
The bead or material inserted into the mollusc to help form a cultured pearl. The size and type of nucleus can influence the final pearl’s shape and size.
Silk Knotting
A traditional method used in pearl strands where each pearl is individually knotted on silk thread to protect the pearls and prevent rubbing.
