Akoya pearls

A traditional, respected classic

Perhaps the most well-known and traditional type of pearl in the world. When many people think of a “classic string of pearls,” the image they almost always think of is Akoya pearls.

Akoya pearls are saltwater pearls and are grown in small sea mussels (Pinctada fucata species and its subspecies). The size of these mussels also limits the size of the pearl, which is why Akoya pearls are usually smaller than, for example, South Sea pearls.

The reputation of Akoya pearls is based in particular on their exceptional luster. Good quality Akoya pearls reflect light almost like a mirror, giving them a bright and “sharp” shine that many consider to be the true hallmark of a classic pearl.

This page is intended to describe specifically cultured Akoya pearls.

Origin and growing areas

Traditionally, Akoya pearls are associated with Japan, where modern cultured pearl production began in the early 1900s. Japan remains a symbol of pearl quality and tradition.

However, today Akoya pearls are also cultivated in China and other coastal regions of Asia. The growing environment, water quality, farming methods and care of the mussels all affect the quality of the pearl that is ultimately produced.

Because of this, Akoya pearls can vary significantly in terms of luster, surface cleanliness, nacre thickness, and overall finish.

The word “Akoya” alone does not tell the whole truth about the quality of the pearls.

Size and shape of Akoya pearls

Usually around 5–9 millimeters in size, larger Akoyas are rarer and more valuable because the size of the shell limits the growth of the pearl.

They are often very round in shape, which is one of the reasons for their popularity in classic pearl necklaces and traditional jewelry. Perfect roundness is rare in nature, so very smooth and round Akoya necklaces are usually of higher quality.

Akoya pearl colors

The most common shades are white, cream, light silver and light pink (rose).

Many Akoya pearls also have an “overtone” or glow that can be pink or silvery, for example. This subtle hue gives the pearls their characteristic, vibrant appearance.

What makes Akoya pearls valuable?

The value is particularly affected by:

- Gloss | The most important quality factor for Akoya.

- Surface cleanliness | The fewer visible defects, the higher the quality.

- Roundness | Perfect shape is rare.

- Thickness of the pearlescent layer | Affects durability and longevity.

- Uniformity | In strings, the uniformity of beads in terms of size and color.

Good quality Akoya pearls will retain their beauty and luster for decades when cared for properly.
