Interesting article - particularly the referencing of the protectionism of the Aus industry via the quota system, and secondly, the recognition that a global grading system could work in the entire industry's favour. Thanks for posting!
Quite an interesting read - and more then a few parallels with the Opal industry.
Those involved spent a number of years forming a cohesive policy on terminology and grading standards to describe and classify their product within the trade and retail environments.
Personally I would like to see a common grading and descriptive terms adopted by the industry - I think it would be very beneficial for both Trade and the retail consumers
