    Default Scientific first used to confirm Age of Ana Maria Pearl

    Pearls, Emeralds, History and now a scientific first - this one has it all

    The Swiss Gemmological Institute have used radiocarbon dating in what is a world first, to confirm the age of an important historical pearl, the "Ana Maria Pearl".

    Gemmologists carefully took a very tiny sample from within the pearl's drill hole in order to do the testing, and the data from this first-ever analysis confirmed that this natural pearl was formed between the 16th and mid-17th century AD.

    See this link for the PDF press release from the institute. https://www.ssef.ch/wp-content/uploa...n-7-5-2019.pdf

    Christie's will be Auctioning it on the 15th if your inspired to buy
