Precision Faceting
I came to faceting via my love of camping and the natural world, this led me to lapidary work in general when I saw my first faceted stone — I just had to know how to do that. This was the beginning of a twelve-year journey. The first stone I cut, a piece of something green, was faceted by hand guessing all the angles by eye. The polish left a lot to be desired but it worked, there was light return: I was 15. I had to wait a further two more years before I gained access to a proper faceting machine, an early Gemmasta, a machine very like the early Sapphire machines seen in the USA. Over the next decade I went to university (which I have returned to, though to a new field this time round), and travelled. In 2005 I built my first machine, a clone of the J-2 as detailed on the Gearloose website; it served me well until I purchased a used Gemmasta GFE-3 faceting machine in 2008. I have been cutting with this now near 30 year old machine on such a regular basis that I know some designs by heart.
