Cygnet Bay Pearl Farm

Nacre thickness

A good quality Akoya pearl can feature a fraction of mm of nacre thickness whereas a South Sea pearl will feature 1.5 to 3mm on average.

Coating refers to the weight or volume ratio of nacre in a pearl. It is considered good above 20%, excellent over 50% and exceptional over 80%.

Sub-standard nacre can be identified visually, but full appreciation requires Xray or tracking of seeding information details.

Wild or hatchery shell

Although the origin of the shell may not necessarily impact all virtues, wild host shell may deliver bigger pearls on average. Australia is the only country running a wild shell fishery now MSC certified. PoA is now able to provide shell origin information via tracking the oyster throughout its life.

Harvest Date

Premium and unique pearls from Pearls of Australia will feature year of harvest.

Cultivation period

Each of our oysters takes approximately 2 years to mature and another 2 years for a pearl to form during which every event and environmental variation is recorded within its layer of nacre.

Other pearls produced in large quantities (such as freshwater pearls) can be cultivated in as little as a few months resulting in a much lower quality.

Pearls are the only gems born of a living organism.

Any mechanical or chemical treatment or enhancement applied to a pearl may dramatically affect its structure, aspect and durability and must be disclosed.
