However, with so many different types of pearls available, it can be difficult to know where to begin. That's why we've put together this guide to pearl grading and how to choose the right type of pearl. By understanding the factors that affect pearl quality and the different types of pearls available, you'll be able to make an informed decision when selecting the perfect pearls for you.

How are Pearls Graded?

Pearl grading is the process of evaluating a pearl's quality based on a set of criteria. There are different systems of pearl grading, but one of the most commonly used is the AAA-A system, which assigns a grade to each pearl based on its lustre, surface quality, shape, and size.

Lustre is the most important factor in pearl grading. It refers to the quality of light reflected by the pearl's surface. A pearl with high lustre will appear to have a deep, glowing sheen, while a pearl with low lustre will appear dull and lacklustre. Pearls with high lustre are typically more valuable than those with low lustre.

Surface quality is another important factor in pearl grading. The surface of a pearl should be smooth and free of any blemishes or imperfections. Even small blemishes can significantly affect the value of a pearl. Pearls with smooth, unblemished surfaces are typically more valuable than those with noticeable imperfections.

Shape is also considered when grading pearls. While perfectly round pearls are the most valuable, there are many other shapes of pearls, including baroque (irregular) and drop-shaped pearls. As long as the shape is consistent and pleasing to the eye, a pearl can still be considered high quality.

Finally, size is also considered when grading pearls. Generally speaking, larger pearls are more valuable than smaller pearls, although this also depends on the other factors mentioned above. The average size of a pearl is between 6-7mm, but pearls can range in size from tiny seed pearls to large, statement-making pearls.

Factors to Consider When Choosing Pearls

When choosing pearls, it's important to consider your personal preferences and the occasion for which they'll be worn. Here are some of the factors to consider:

  • Lustre: If you're looking for pearls that will stand out and make a statement, choose pearls with high lustre. If you prefer a more understated look, choose pearls with lower lustre.

  • Surface quality: If you're looking for pearls that will be worn often and subject to wear and tear, choose pearls with fewer surface imperfections. If you're looking for pearls that will only be worn occasionally or for special occasions, you may be willing to accept more surface imperfections.

  • Shape: Consider the shape of the pearls and how it will complement the design of the jewellery. Round pearls are classic and versatile, but other shapes like baroque and drop-shaped pearls can add interest and uniqueness to a piece.

  • Size: Consider the size of the pearls in relation to the design of the jewellery and the occasion for which it will be worn. For formal events, larger pearls may be more appropriate, while smaller pearls may be more suitable for everyday wear.

Understanding the Types of Pearls

When it comes to choosing pearls, it's important to understand the different types of pearls that are available. Here are some of the most common types of pearls:

    1. Akoya Pearls. Akoya pearls are a type of saltwater pearl that is produced by the Akoya oyster. They are typically small to medium in size, ranging from 2mm to 10mm, and are known for their high lustre and round shape. Akoya pearls are often used in classic pearl jewellery designs and are a popular choice for bridal jewellery.

    2. South Sea Pearls. South Sea pearls are some of the largest and most valuable pearls in the world. They are produced by the Pinctada maxima oyster, which is native to the South Seas. South Sea pearls are typically white, silver, or gold in colour and range in size from 8mm to 20mm. They are known for their high lustre and are often used in high-end jewellery designs.

    3. Tahitian Pearls. Tahitian pearls, also known as black pearls, are produced by the Pinctada margaritifera oyster, which is native to French Polynesia. They come in a variety of colours, including black, grey, green, and blue, and range in size from 8mm to 16mm. Tahitian pearls are known for their unique, exotic beauty and are often used in statement pieces.

    4. Freshwater Pearls. Freshwater pearls are produced by freshwater mussels and are typically smaller than saltwater pearls, ranging in size from 2mm to 12mm. They come in a variety of shapes, including round, oval, and baroque, and are known for their affordability and versatility. Freshwater pearls are often used in more casual, everyday jewellery designs.

      Freshwater pearls are generally considered to be a sustainable type of pearl. This is because they are typically farmed in a more environmentally friendly way. Freshwater pearl farming often involves the use of natural bodies of water, such as lakes and rivers, which helps to minimise the impact on the environment.

Selecting the perfect pearls

Natural vs Cultured Pearls

Another important factor to consider when choosing pearls is whether to choose natural or cultured pearls.

Natural pearls are extremely rare and valuable, as they are formed by chance when an irritant, such as a grain of sand or a small parasite, becomes trapped inside an oyster or mussel. The oyster or mussel then secretes layers of nacre around the irritant, forming a pearl. Natural pearls are extremely difficult to find and are typically very small in size.

Cultured pearls, on the other hand, are produced by intentionally introducing an irritant into an oyster or mussel. The oyster or mussel then secretes layers of nacre around the irritant, forming a pearl. While the process is not entirely natural, cultured pearls can still be of very high quality and are much more affordable than natural pearls.

When choosing between natural and cultured pearls, it's important to consider your budget and your personal preferences. While natural pearls are extremely rare and valuable, they are also very expensive and may not be practical for everyday wear. Cultured pearls, on the other hand, are much more affordable and come in a wide range of sizes, shapes, and colours, making them a great choice for everyday wear or special occasions.
