"If you work with diamonds, unless you've already done this workshop, you need to do this workshop. You don't have time to research and learn all this stuff yourself. Julia hands it to you on a plate. It's not cheap, but it's exceptional value for money, and in the long run will save you time, money and stress.

It was simply excellent... I left having the confidence I wanted. Julia has spent years researching and gaining experience, to distill it down into one day, so I didn't have to."
