Thinking of purchasing a pearl necklace for yourself or someone special in your life? Wondering how to choose between freshwater and saltwater pearls? This is the guide you’ve been searching for.
Freshwater vs. Saltwater Pearls: The Basics
Let’s start by outlining some of the key differences between freshwater and saltwater pearls.
Shape
- Freshwater Pearls: Tend to have a more irregular shape, often oval, baroque or slightly off-round. However, round freshwater pearls do exist.
- Saltwater Pearls: More likely to be perfectly round. The layers of nacre tend to form more symmetrically.
Lustre
- Freshwater Pearls: While they can have a lovely lustre, they typically have a softer, more subdued shine compared to saltwater pearls.
- Saltwater Pearls: Known for their intense lustre and brilliance, especially in Akoya and South Sea pearls.
Colour
- Freshwater Pearls: Available in a wide range of natural colours, from white and pink to lavender and peach.
- Saltwater Pearls: Tend to have more traditional colours, such as white, cream, silver, or black (Tahitian pearls), but can also exhibit rare hues depending on the type.
Price Comparison: Why Saltwater Pearls Are Often More Expensive
Saltwater pearls are usually more expensive due to their rarity, cultivation process and quality.
Unlike freshwater pearls, which are produced in larger quantities and can grow in a variety of environments, saltwater pearls are cultivated in specific and delicate ocean conditions.
The process of growing saltwater pearls is also more time-consuming, with some pearls taking several years to form, particularly for sought-after varieties like South Sea and Akoya pearls.

Durability and Quality: Which Pearl Lasts Longer?
When it comes to durability and quality, freshwater pearls typically last longer than saltwater pearls due to the thickness of their nacre.
Freshwater pearls are more resistant to chipping, wear and damage over time. Their thicker nacre also provides more durability for everyday wear.
Saltwater pearls, especially Akoya pearls, have thinner nacre layers, which makes them more delicate and prone to damage if not cared for properly. However, South Sea and Tahitian saltwater pearls, with their slightly thicker nacre, offer better durability than Akoya pearls. However, they are still generally more delicate than freshwater pearls.
In terms of quality, saltwater pearls have better lustre, shape and brilliance, but their thinner nacre means they require more careful handling and maintenance to preserve their beauty.
Choosing the Right Pearl Necklace for You
Ready to invest in a pearl necklace? Before you do, here are some questions you’ll want to ask:
Why are you buying a pearl necklace?
If you’re looking for an everyday piece, a simple freshwater pearl necklace is affordable and versatile.
For special occasions or formal events, saltwater pearls such as Akoya or South Sea pearls provide a more luxurious, high-end look.
How big do you want to go?
Smaller pearls (6-8mm) offer a classic, understated elegance. They’re ideal for everyday wear or layering. Larger pearls (9mm and above), on the other hand, make a bolder statement.
What pearl type are you interested in?
Freshwater pearls are more affordable, come in a variety of colours and shapes, and are ideal for a range of budgets. If you’re willing to pay more though, saltwater pearls will give you that beautiful round shape and more lustre.
What colours do you prefer?
White and cream pearls are classic and suit most skin tones. However, if you want something a little different like pink or peach, freshwater pearls are a great choice.
Final Thoughts
In the end, choosing between freshwater and saltwater pearls depends on your personal preferences, budget and the occasion.
Freshwater pearls offer a more affordable and versatile option, while saltwater pearls make a luxurious statement.
