Did you know that most gems are many million years old? When I precision cut a gem it will yield around 20 %. More or less. Its expensive rough and anything can happen to it while I´m cutting. I will lose a lot of money in gemmaterial every time I cut a gemstone. So Why do I do this? To be able to follow a gemstone and see what is happening with it when I cut it,is so special. It will be worth more after cutting. I love the challange. I love to show the gems inner beauty to gem lovers around the world.
