The Journal
Field notes from the source. What a stone passes through before it becomes a piece.
Stone notes
The questions buyers ask before they buy, answered by the person who selects the stones.
Reading a gem report
What a laboratory document actually tells you, and the one thing buyers always expect it to say that it never does.
Choosing a cut
Why a marquise reads longer on the hand, why a cushion holds colour, and how the shape you choose changes the stone you need.
What colour actually costs
In coloured stones, size is rarely what you are paying for. Three qualities decide the price, and only one of them is visible in a photograph.
