Oh my goodness!
You can learn a lot and be moved by watching the master's videos! thank you very much!
I like Mr. Jeff Graham, and I was also curious about this oval cut, so I was thrilled to see it!
And I'm thrilled to be able to see the best work created by the master's perfect work!
Thank you for teaching me the importance of length and width! Another mystery solved!
Recently, I learned that there is a subtitle function, so I'm happy to watch my master's videos! Also, the giant sapphire is amazing!
It's the first time I've seen that shape♪
It's thick and very nice!
Thank you as always, I respect and appreciate it! !

I digitized this design in GCS and ended up with a Table just like yours turned out ... not touching all of the Star Facets as one might like.
I have since been trying to change the angles of the crown facets to rectify this issue so that the table, nicely intersects each of the Star Facet Meet Points. I'm not there yet. Had to put it aside for the time being.

When you get the design to be almost perfect, please send the GCS file! Thanks!

Love the cut. Btw, are you selling any pieces of that rough sapphire?

[@BOPIESDiamondsFineJewelry]
