Similar to how freshwater pearls evolved into a more cost-effective alternative to Akoya pearls, the production of Edison pearls had it set to compete with the highly valued Australian South Sea pearls. When they initially launched, the pearls were extremely costly, but now many recognize them as less expensive substitutes for the South Sea pearl.

How Are Edison Pearls Made?

Edison pearls are freshwater pearls; they have adapted the saltwater farming method of nucleating an oyster employing round beads. Nonetheless, there have been exclusive improvements to this method. Although Edison pearls are a kind of cultivated freshwater pearl, they form using entirely different technologies. 

If you interpret it straight from Chinese, the peculiarity of this pearl formation attributes to a little element known as a "spit bead." When an oyster "spits out" the bead core implanted to produce a pearl, the process refers to "spit beads" or, more precisely, the expulsion of implanted beads by oysters.

To produce precisely round pearls, the inventors of the Edison pearl used the bead nucleating method on their freshwater mussels. Additionally, they nucleate the Edison pearl mussels with a single bead as opposed to most freshwater mussels, which use numerous pieces of tissue to produce up to 50 freshwater pearls at once. The mussel can concentrate all of its efforts on only one pearl.

Bead core implantation into mollusks is only sometimes effective. The implanted bead may be rejected or "spit out" by the mollusk. This rejection rate is typically high compared to that created in China, which is approximately only 5% in China. These production statistics demonstrate the technological superiority of the Edison pearl farming method, the vastly different production output, and the financial returns put in place.

Edison vs. South Sea Pearls

Several factors clearly distinguish between the Edison and the South Sea pearls. Some of these major factors include:


The Edison pearls refer to freshwater pearls, usually forming in streams, rivers, or lakes. However, the South Sea pearls are saltwater pearls cultured in the ocean. The two primary varieties of South Sea pearls are white and gold. 

The white south sea pearl grows mainly in the seas off of northwest Australia, and the gold south sea pearls at the Philippine Islands. Compared to the South Sea Pearls, Edison Pearls primarily grow in China Lakes.

A variety of colors, including pink, plum, lavender, white, metallic cream, gold, and deep purple, are available in Edison pearls. While certain pearls might have a gray hue, dye is prevalent on all black Edison pearls. The pearls' stunning overtones and superb orientation further highlight the stone's brilliance.

However, colors for the South Sea pearls are limited to the white, yellow, and black color series. Thus the pearls come in shades like milky white, golden, champagne, silvery-white, and a few others.

Edison pearls typically range in size from larger than 11mm, with the most prominent between 11 mm and 12mm. This size is feasible because just one bead is ever introduced into the mussel per time, and the pearl has more time to mature.

Although the Golden and White South Sea pearls grow to significant sizes, about 14.0 to 15.0mm, however, for the same price, you can acquire Edison pearls with more outstanding shine.

Nacre thickness is one of the determinants of the quality of pearls. The typical nacre thickness of a South sea pearl is 2.3 mm, but that of an Edison pearl ranges from 2.0 to 3.5 mm for pearls of similar size. Both pearls are of high quality, with the Edison pearl slightly higher.

It is simpler to manage and enhance the water quality of the Edison pearl because of its cultivation in freshwater. Conversely, because of the South Sea pearls' cultivation in the sea, where water quality is challenging to regulate, their production is significantly more expensive. 

This regulation has a significant impact on how much these pearls cost. So, Edison pearls are substantially cheaper than South sea pearls of the same quality.
