Over 40 Degrees
« on: December 12, 2010, 10:19:17 PM »
If a cushion cut has a GIA note that it's angles exceed 40 degrees, should I be deterred from buying it?

Not necessarily, but you do want an expert to look at it to understand what is the reason for such a steep crown.

If you are getting a vintage cut or a "look alike" that is completely normal to see in a cushion.  If you aren't then I would definitely be asking more questions from the seller or maybe an appraiser to see what is going on with the stone.

Don't colored stones sometimes have a steep angle? I thought they were cut that way to get the maximum amount of color out of the stone.....I could swear I have heard that somewhere......

ANF, is this about the same fancy grayish yellowish green stone from the other thread?

No actually, it is about a natural light green that was my other consideration instead of the olive stone.  It is green with no modifiers and SI1.  To my eye it looks beautiful with a light greenish ocean color but there is the angle note.  Maybe it is why the stone is closer to my price range, but I don't want a dud.  I would rather wait.

if it's a natural light green, that would explain the 40 degree angle to me. stones with light color are sometimes cut that way to maximize the color. It probably does sacrifce some sparkle though. do you have a pic of the one you bought?

Saqsay is correct about maximizing color, but it's sometimes done also to maximize carat weight. Translation - $$$$.  It is a pretty stone.  If you look at the picture you posted and some on the DBL website, you can get an idea of how the different depths and angles affect the play of light inside the diamond. You can't always look at numbers, though.  You have to see the diamond in person to make your decision.  Love the make on the other one, too.

Hi DiamondsAreForever - Thanks for the insight.  BTW, did you mean love the make on the one I posted in the colored diamond forum (topic: cloud)?  Because, I am really looking for feedback on that.
