Round Brilliant Cut Diamonds

Video Transcript

"This is the standard American round brilliant cut. It is designed to produce the optimum in prismatic effect which that is what everyone wants to see is he prismatic effect from a diamond as opposed to the sparkle. The sparkle you can get from a mirror. But a mirror is not going to give you the spectrum of color like a diamond will when it is cut properly. In this case you should have the correct proportions of the table from the table down to the girdle and then you should have the correct proportion of the bottom which is the pavilion. With all of these angles and proportions in place and your table with a certain table being the flattest part, with all of these proportions correct you should have an ideal cut stone which will give back to you the maximum amount of prismatic effect and this is the ooh or the ahh that your neighbor or the person next to you sees and says oh my goodness look at that stone. That is what you really want when you buy a diamond that is cut correctly."
