How to choose Akoya pearl?

Akoya pearls, known for their stunning luster and classic appeal, are a popular choice for jewelry enthusiasts around the world. Whether you’re a seasoned collector or a first-time buyer, understanding the nuances of these pearls can help you make an informed decision. This comprehensive guide will walk you through everything you need to know about Akoya pearls, from understanding their origins to tips for purchasing and maintaining them.


Understanding Akoya Pearls

History and Origin

Akoya pearls are cultivated primarily in Japan and China, with Japan being the pioneer and still the most renowned producer. The cultivation of Akoya pearls began in the early 20th century, with Kokichi Mikimoto being a notable figure in their development. Mikimoto’s dedication to perfecting the pearl culturing process led to the high-quality, perfectly round pearls that are now synonymous with the Akoya name.


Cultivation Process

Akoya pearls are typically cultured in the Pinctada fucata martensii oyster. The process begins by inserting a small bead and a piece of mantle tissue into the oyster. The oyster then secretes layers of nacre around the bead, forming a pearl over a period of 10-18 months. This meticulous process requires careful monitoring and ideal conditions to produce high-quality pearls.


Akoya pearls are prized for their mirror-like luster and perfectly round shape. They typically range in size from 3mm to 10mm, with sizes over 8mm being rarer and more valuable. The colors of Akoya pearls are generally white or cream with overtones of pink, silver, or ivory. The surface of these pearls is usually very smooth, with minimal blemishes.

Quality Factors

When choosing Akoya pearls, several quality factors should be considered to ensure you are selecting the best possible pearls for your needs. These factors include luster, surface quality, shape, size, and color.


Luster is the most critical quality factor for Akoya pearls. It refers to the sharpness and intensity of reflections seen on the pearl’s surface. High-quality Akoya pearls will have a bright, mirror-like luster, while lower-quality pearls may appear dull or chalky. To assess luster, hold the pearl under a light and observe the sharpness of the reflections.

Surface Quality

The surface of the pearl should be as smooth as possible with minimal blemishes. Common surface imperfections include spots, bumps, or pits. While some minor imperfections are acceptable, especially if they are not visible to the naked eye, pearls with significant blemishes should be avoided. Surface quality impacts the pearl’s overall appearance and durability.


The shape of Akoya pearls can vary, but they are most renowned for their near-perfect roundness. While perfectly round pearls are the most valuable, near-round, oval, and baroque shapes are also available and can be beautiful and unique in their own right. The choice of shape largely depends on personal preference and the intended use of the pearls.


Size is another crucial factor in determining the value of Akoya pearls. Larger pearls are more rare and generally more expensive. While Akoya pearls typically range from 3mm to 10mm, those over 8mm are particularly sought after. When choosing the size, consider the intended use – smaller pearls are ideal for earrings and rings, while larger pearls make a statement in necklaces and bracelets.


Akoya pearls come in a range of colors, with the most common being white or cream with overtones of pink, silver, or ivory. The color should complement your skin tone and personal style. Pink overtones are often preferred for their classic, feminine appeal, while silver and ivory overtones offer a more neutral look.

Care and Maintenance

Proper care and maintenance are essential to preserve the beauty and longevity of Akoya pearls. Pearls are delicate and require special attention compared to other gemstones.


To clean Akoya pearls, use a soft, damp cloth to wipe them after each wear. This removes any oils, sweat, or other residues that may have accumulated. Avoid using harsh chemicals, ultrasonic cleaners, or steam cleaners, as these can damage the nacre. For a deeper clean, use a mild soap solution and a soft brush, rinsing thoroughly and drying with a soft cloth.


Store Akoya pearls separately from other jewelry to prevent scratches. Ideally, keep them in a soft pouch or a lined jewelry box. Pearls need moisture to maintain their luster, so avoid storing them in excessively dry or air-tight conditions. If you live in a dry climate, consider placing a damp cloth near your storage area to maintain humidity.


When wearing Akoya pearls, put them on last and take them off first. This minimizes their exposure to perfumes, hairsprays, and makeup, which can damage the nacre. After wearing, wipe the pearls with a soft cloth to remove any residues.

Purchasing Tips

Choosing the right Akoya pearls involves more than just understanding their quality factors. Here are some practical tips to help you make a wise purchase.

Buying from Reputable Sellers

Always buy Akoya pearls from reputable jewelers or dealers. Look for sellers who provide detailed information about the pearls’ origin, quality, and any treatments they may have undergone. Reputable sellers should also offer a certificate of authenticity and a fair return policy.

Understanding Grading Systems

Familiarize yourself with the grading systems used for Akoya pearls. While there is no universal grading system, most sellers use similar criteria to grade luster, surface quality, shape, and size. Understanding these grades can help you compare pearls from different sellers.

Price and Budget

Set a budget before you start shopping for Akoya pearls. Prices can vary significantly based on quality factors and the seller’s reputation. While it’s essential to find pearls that fit your budget, avoid compromising on quality for the sake of a lower price. High-quality Akoya pearls are an investment and can last a lifetime with proper care.

Customization and Setting

Consider how you want to use the Akoya pearls – whether in a necklace, bracelet, earrings, or a ring. Customization options, such as matching pearls for a set or choosing specific settings, can enhance the beauty of the pearls. Work with a jeweler who can help you design the perfect piece of jewelry to suit your style and preferences.

Certification and Documentation

Ensure that the Akoya pearls come with proper certification and documentation. A certificate of authenticity from a recognized gemological institute or a trusted jeweler provides assurance of the pearls’ quality and origin. This documentation is also valuable for insurance purposes.

Ethical and Sustainable Practices

Consider the ethical and environmental practices of the pearl farmers and sellers. Sustainable pearl farming practices ensure the health of marine ecosystems and fair working conditions for those involved in the cultivation process. Look for sellers who are transparent about their sourcing and commitment to ethical practices.


Choosing Akoya pearls involves understanding their unique characteristics and quality factors, proper care and maintenance, and making informed purchasing decisions. By considering factors such as luster, surface quality, shape, size, and color, and by following practical tips for buying and maintaining these pearls, you can enjoy the timeless beauty and elegance of Akoya pearls for years to come. Whether you are adding to your jewelry collection or purchasing a special gift, Akoya pearls are a stunning and sophisticated choice that never goes out of style.
