If you choose the first diamond on the left, then you really have a good eye!

       I'm doing a diamond consultation for a client。 He sent me a link, yesJames Allen Diamond trader's stock75A fine cut, and meet the customer's cleanliness, color and other requirements of the diamond.The question he gave me was simple。 Which well-cut diamond should I buy? I looked it up75Information on a fine cut diamond identified which ones were most likely to meet my selection criteria。 It's really a little game I like to play because of the past30All my efforts have been focused on researching and seeking the most ideal cut diamond。 I clicked on each diamond image to see their details。 I then open the grading report for each diamond so I can see the details。 I think this can be a practical lesson in how to choose the best cut diamond。

Obviously, this one1.07carat,G-color,VS-2clarity,GIAExcellent cut round diamond32。0Crown Angle and41.0The Angle of the bottom is out of our standard. I should also point out the Angle of the crown,43.5%The depth of the bottom is exactly the point at which light starts not reflecting off the surface of the diamond。 This will result in a reduction in light and shadow refraction。 I don't recommend buying this diamond。
