designer_replica Jaeger LeCoultre 270.51.20 watch Cut refers to how well proportioned the diamond is. For example, what percentage of a diamonds diameter is its depth? What are its various angles and how do they interact with one another? While these may seem like esoteric questions, these are the essential factors that determine how beautiful your diamond will be. For a great visual representation of why these issues matter, have a look at James Allen page on Diamond Cut.Diamond Cut Grade — All that MattersUntil January 1st, 2006, you basically had two options when it came to diamond cut grade. You could either buy a diamond with an AGS certificate and trust their diamond cut grading system, or you could learn about the various proportions of diamond cut and trust your own education about what numbers translated into a beautiful diamond. On that day, though, the GIA introduced a new certificate format that included their very own diamond cut grade. They claim that their Diamond Cut Grade system is based on 15 years of research testing and retesting different combinations of measurements with real life light performance tests. As opposed to the AGS system which simply defined what an ;ideal; diamond is and then gives lower grades the farther away from that designer_replica Jaeger LeCoultre 270.51.20 watch; the parameters are (see table to the left), the GIA system does not have any one single definition of perfection. They claim that in their research various differing combinations of proportions equally produced diamonds that reflected the most light. So while in the AGS model, a diamond with a table size of 60% is automatically penalized to a Diamond Cut Grade of ;2,; (on a scale from 0 to 9), with the GIA model, there still a chance the diamond could receive an ;Excellent; grade if the rest of the parameters are the best possible parameters that combine with a 60% table.In my opinion, the GIA system is clearly a much more elegant solution to the question of what cut proportions produce the most beautiful diamonds. And the fact is, it a more elegant solution than your typical diamond dealer instincts designer_replica Jaeger LeCoultre 270.51.20 watch.
