NOTE: It is an unfair trade practice to misrepresent the weight of any natural or cultured pearl or to deceive as to the weight of any natural or cultured pearl. It is also an unfair trade practice to state or otherwise represent the weight of all natural or cultured pearls contained in any article unless such weight figure is accompanied with equal emphasis and prominence by the words “total weight”, or words of similar meaning, so as to indicate clearly that the weight so stated or represented is that of all pearls in the article and not that of the centre or largest one. (reference: saltwater pearls wholesale )
NOTE: The SI (Système International) generally uses the term mass instead of weight. Mass is a measure of an object‘s inertial property, or the amount of matter it contains. Weight is a measure of the force exerted on an object by gravity or the force needed to support it. (reference: saltwater pearls wholesale )
