About John Bradshaw


John has a background in chemistry and was working as an epoxy chemist when he took up faceting in 1979.  A short time later, he gave up his chemists’ job to become a full time lapidary.  He held the position of Curator of gemstones at the Harvard Mineralogical Museum for twenty years.  John specializes in the finer “jewelry” type stones although he cuts the whole spectrum from soft to hard.
