Recently I started reading an article or maybe a part of a book written a few years ago by a  gent who I think  resided on the Qld. gemfields. 

The part I read was about  step  cut crowns with  brilliant pavillions.

At the time I was travelling and have lost not only the article but his name.

Perhaps some-one here can shed some light on a possible name  as I would like to re-read the article.
