Bidders must assume that diamonds and coloured gem stones (including ruby, emerald, sapphire, peridot, aquamarine) may have undergone a form of treatment unless otherwise stated. It should not be assumed that any diamond or coloured gem is untreated or is natural, unless accompanied by a gemmological laboratory certificate (which would be mentioned in the description). McTear’s will only describe gold/platinum/silver as such when a full UK standard set of hallmarks is present on the object. Other marks such as foreign import stamps will be noted in the description.
