Akoya Pearl


The Akoya pearl is a saltwater cultured pearl from the Akoya oyster (阿古屋貝). Akoya pearls are the most familiar type of saltwater cultured pearl in Singapore and other Asian markets. We love Akoya pearls for their signature bright mirror-like lustre.

The majority of the world's Akoya pearls are produced in Japan. The high lustre found in our top-quality Akoya pearls and their relative rarity gives Akoya pearls a higher perceived value.

An average Akoya pearl is 7 mm; Akoya pearls are currently being harvested in sizes from as small as 1 mm up to the very rare 10-11 mm; both mini and jumbo sizes are rare and sought after. Akoya pearls usually come with a pink, white, or silver overtone. Many customers think of white or cream-colored Akoyas as the classic pearl used for jewelry, especially single-strand necklaces.

  • SIZE

    Cultured pearls range from 2-16mm in diameter, depending on the mollusk used.


    Spherical pearls are the most valued but symmetrical drops are also sought.

  • Luster

    Pearls with high luster have sharp bright reflections on the surface.


    The number of blemishes on a pearl's surface is evaluated to judge quality.


In general, the larger the pearl, the more valuable it is. Different varieties come in different sizes: South Sea cultured pearls are the largest.


Round is the most difficult shape to culture, making it the rarest cultured pearl shape and—if all other factors are equal—also generally the most valuable. There are exceptions, though. Well-formed pear, oval, or baroque (irregularly shaped) cultured pearls are also prized by pearl lovers. Different pearl types are held to different standards when classifying
shape. Japanese saltwater cultured pearls are held to the strictest standards for shape.


Of all pearl quality factors, lustre might be the most important. Lustre is what gives a natural or cultured pearl its unique beauty.

Aslowe only uses pearls with very good or excellent lustre.


Like colored stones, most pearls never achieve perfection. Some might show abrasions that look like a series of scratches on the surface, or a flattened section that doesn’t affect its basic shape, or an irregular ridge that looks like a crease or wrinkle.

If surface characteristics are numerous or severe, they can affect the durability of the pearl and severely depress its value. Surface characteristics have less effect on the pearl’s beauty and value if they are few in number, or if they are minor enough to be hidden by a drill-hole or mounting.

Pearl is the birthstone for June and the gem of the third and thirtieth anniversaries. The Akoya oyster is the smallest commercially farmed, pearl-producing oyster.


With proper care, pearls last generations. Wipe it clean with a soft cloth after wear and store it in your Aslowe jewelry box or pouch. Avoid exposure to heat, perfume, or cosmetics.
