When Standards for Gem Cut Grades Unified?
On February, 16th,2008, Mr.Garry H. quoted an article Philosophic question about diamond advertising on the Internet, which caused a great response. The theme of this article was: When would be the standards for Gem Cut Grades unified?
Obviously, it is impossible to unify the grades standards by experience. Contrarily, depending on the pure scientific theoretical study achievement can realize the unification. Everyone is equal in front of experience and obedient to science. That is truth!
GIA promoted a free soft for grades standard on the market in 2004. It has made 70,000 observations on 2300 diamonds' cut facets, and this soft was a standard system established on the basis of plenty of those observational data. That could be considered as an actual effort on empiricism, hard and clumsy. Nevertheless, few people admitted GIA's achievements, for each had his own experience and nobody would like to be convinced. That is a worldwide truth, Everyone is equal in front of experience.
However, Human beings admit and obedient to science. Therefore, unifying the grades standard by science is the only proper method.
The essence of grades standard is gem cutting database – processing rules system, for cutting data determines cutting quality. The essence of gem cutting database is cutting equations -- continuous function, for cutting equations determine the theoretical database. Thus, grades standard has close relationship with cutting equations, which means grades standard system and processing rules system cannot be separated.
To unify grades standard, we must apply cutting equations as the scientific theory which has the only qualification. It is the same with processing rules system. In a word, only cutting equations (continuous function) can be scientific theoretical support to realize the unification of processing rule system and grades standard system. it is a scientific logic, incontrovertible!
Fortunately, we have already obtained the cutting equations and a scientific theoretical database by calculation. It is a curve function, in which every parameter of every group of data is different from other groups of data. For instance, the group of data which table proportion is 53% is the only group. Among raw materials with infinite kinds of shapes, there is only one the most suitable for the only group of data. That is the differences between traditional database and ours. That is the differences between experience and science. That is also the scientific theoretical support for unifying processing rules system and grades standard system. We sincerely hope this theory can be validated and brings a modern era in diamond industry.
Science is charming and irresistible. The best way to protect the coming benefits is to adopt science instead of maintaining empiricism.

How nice! This is a great bit of text!
Reminds me of a famous quote from my field: "Theory is evidence too"
Along with the author, I also hope that:
Quoting Mr. LangchunWei: [...] this theory can be validated [since] The best way to protect the coming benefits is to adopt science instead of maintaining empiricism.
Another famous quote from my field says: "It takes a theorist to pierce a theorist's hide" ... and my feeble amount of experience gives that there's always such a theorist awaiting with a piercing rod
I think this also answers Garry's question. In fact, the answer does not appear that hard to guess. Providing proof is another matter, especially if one aims to observe the old fashioned link between experimental (or empirical, SIC!) evidence and theoretical construction... with or without the added spice of social discourse.
And the answer is.... [insert drum roll].... Ah! Forget it!
I'd recommend two bits of reading for interested folks: one about how the structure of markets alters innovation by Thomas Cooley, the Dean of Stern [Innovation, Imitation, and Market Structure; Thomas F. Cooley and Mehmet Yorukoglu], and another well, you'll see what it is about (HERE).
If the refs. sound a bit eclectic, don't worry... you'll find the relation in a blink and have a laugh too.
Following this strife for the perfect diamond has been such fun, I'd hate to see it end any time soon. Not that's any danger.

Of course, and those that don't stay at the starting point and the others move on. Or just dont show up for the happy parade
Wouldn't a square drum make as much noise?
I never saw a square drum yet..., and if there are square drums..., they dont sound like the round ones A parade starts when the leader takes the first step.[/quote][/quote][/quote]

Exactly, as you so eloquently point out, the geometry of the drum changes the sound as does the geometry of a diamond change the Brilliance and Sparkle. Both conclusions based upon geometry an honorable science.
