I believe you may be right there Garry, based on minor email contacts I''ve had with him in the past.

100 Questions about Cut Grades Standard
----New World and Old World ¢ñ

1. It is a scientific research topic to study the theoretical basic for grades standards of cutting quality and determine the continuous functions and theoretical database which stand for the theoretical basic. Studying the commercial grades and making quality certificates is a practical application of this scientific research topic. Scientific research topic is not equal to practical application. Scientific research topic should be higher than practical application, and the latter has no qualification to replace the former.
However, Reality is not like that. Diamond industry has become a heaven for some businessmen to cheat and even the high-tech has become an instrument to confuse consumers.
The fundamental cause is that scientific topic was deserted for a long time, thus experience dominated everything. Some businessmen use high-tech to make up experience and deceive cut industry and consumers.

2. Every consumer has the right to enjoy science and know that what they enjoy is not science. None of the institutions have reason to destroy or deprive of their right.
Now who can take the responsibility to clearly tell his consumers whether they are enjoying science or experience in his own grades report. More importantly, whether we should say clearly about this issue? Should a moral businessman say it clearly before required by regulations?

3. I presented several conceptual academic issues and published several argumental academic articles, main ideas of which are: ¡±Our industry should clearly know who is scientific, who is experiential, what is scientific and what is experiential.¡± However, since the obtained interest does not accord to the science, the responses in the industry are not correspondent. In such a situation, how could be the diamond consumers¡¯ rights and interests ensured.

4. Regulating grades standards and making quality certificates is obviously an important thing, which relates to everyone¡¯s big interest. We have already attained cutting continuous functions and theoretical database, and is there any reason for us to maintain the present non-unified situation of empiricism?

5. Could we carry out a temporary industry regulation before unification: When making quality certificates, it is suggested to print an explanation on the cover ¨C the grades standard system of this certificate has not been proved by a continuous function, and it is experiential rather than scientific. Hereby certify!¡±

6. In all ages, people¡¯s cognition of ¡°round¡± went through a historical process from experience to science. There are four main stages.
1) The early cognition is a rather primitive stage, learning to produce round objects such as wheels and buckets. The characteristic of this stage is ability of production.

2) Later, people learned to draw a round by simple instruments and gradually drew better. The characteristic of this stage is ability of drawing a round.

3) Then, people gradually knew what was round¡¯s continuous function. The characteristic of this stage is ability of calculation.

4) At last, people knew unit round¡¯s continuous function is so simple: X²+Y²=1. The characteristic of this stage is ability of expansion.

Thus, which stage are we standing on as to the topic of diamond cutting quality? Unfortunately, diamond cut industry still stays on the primitive cognitive stage, production.
Can people reach scientific cognition in the future? How long will people stay on the primitive experiential level? Is there any businessman who is trying to delay us into scientific level? Why are they preventing scientific progress? Is the worry necessary? How many persons who have such worry?

7. The scientific theoretical basic of grades standard for cut processing quality is a continuous function. Is it as simple as unit round? Would you believe if I tell you that it is really simple?

8. What is the best cut quality? Is there ever a continuous function to prove what kind of cut quality is the best?
AGSL, GIA and EGL are the most famous three chief gem laboratories. They have assessed 128 diamonds as the best. However, EGL cannot determine a single best cut quality.
If people cannot apply a continuous function to proving the best cut quality, how can they know what the best cut quality likes? It is similar to the situation of round. Before ancient people knew the continuous function of round, they tried by empiricism when assessing the most orbicular round, difficult to be correspondent.

9. Why can¡¯t they answer the consumers in public: Is the present grades standard system scientific or experiential? Is there a continuous function to prove the best cut quality? If it cannot be proved, how much scientific content and value do the other grades certificates have?

10. There are too many questions for us to confront.


100 Questions about Cut Grades Standard
----New World and Old World ¢ò

10. We can sort out three types of implementary methods of cut quality grades standard. Firstly, analyze cutting database to determine the class. Secondly, apply 3D Computer Model to determining the class. Thirdly, Use instrumental measure to determine the class. Among these three methods, the second one is the most famous. However, all of these three methods are experiential and cannot be proved scientifically by continuous functions.
