Three definitions

Section 23.19 defines a pearl as one formed inside certain mollusks without any human cause; a cultured pearl as the product made when a nucleus planted by humans inside a mollusk is coated with nacre by the mollusk; and an imitation pearl as a manufactured product that looks like a pearl or cultured pearl.

The word "pearl" alone

Section 23.20(a) says the unqualified word "pearl" should describe only a pearl as defined in section 23.19(a).

Cultured first

Section 23.20(b) says a cultured pearl should be described with "cultured" or "cultivated" immediately before the word pearl, with equal conspicuousness.

Freshwater, Akoya, and South Sea

The FTC says naming only the type, such as freshwater, South Sea, or Akoya, will not do. Its examples are "cultured freshwater pearls", "South Sea cultured pearls", and "Akoya cultured pearls". Section 23.21(g) ties "South Sea cultured pearl" to salt water mollusks of the Pacific Ocean South Sea Islands, Australia, or Southeast Asia.

Imitation pearls

Section 23.20(c) and (d) say an imitation pearl should carry "artificial", "imitation", or "simulated" immediately before the word, and that terms such as "faux pearl" and "fashion pearl" need the same qualifier.

Pearl treatments

The FTC lists bleaching, dyeing, and irradiation to change a pearl's color. Section 23.23 says when a treatment of a pearl or cultured pearl should be disclosed.

FAQ

The FTC says a listing should state that pearls are cultured, as in "cultured freshwater pearls". Read the seller's description.
