Hi Lycos,

Can you post the crown and pavilion angles please?

 

[lycos]

crown angle is 34 deg and pavilion is 41.2 deg
hope this helps

Not that good. The pavilion angle is steep, there will be some light leakage. Can you get a Idealscope image from them? If not I will give this stone a miss.

Ditto, I would prefer a less steep pavilion angle especially if an Idealscope image is not a possibility.

what should be the proper angle for crown or pavalion
thanks for response

 

[stone-cold11]

Sliding scale, roughly 41 degree for a crown angle of 33.5degree to 40.7 degree for a crown angle of 35degree.

Use the https://www.pricescope.com/cutadviser.asp to weed out bad performing combination, any stone scoring above 2 is not consider a good candidate unless IS/ASET image is available.

This should help you from expert John Pollard.

"As the above implies, configurations depend on each other. A little give here can still work with a little take there.

With that said, here's a "Cliff's Notes" for staying near complementary angles with GIA reports (their numbers are rounded): A crown angle of 34.0, 34.5 or 35.0 is usually safe with a 40.8 pavilion angle. If pavilion angle = 40.6 lean toward a 34.5-35.0 crown. If pavilion angle = 41 lean toward a 34.0-34.5 crown.

GIA "EX" in cut is great at its heart, but it ranges a bit wider than some people prefer, particularly in deep combinations (pavilion > 41 with crown > 35)."

Try to keep pavilion angles 41 degrees or less to be safe.
