"Round Brilliant Dome #2" - Cutting Remarks

Here is an interesting cut. This is pretty easy to cut and it not that different than a regular round brilliant it is ideal for a less experienced cutter. The crown is where most of the differences are, as you can see it is domed for effect and it will also retain a fair amount of weight in the finished stone.

This design is intended to be cut in to a medium to a large stone (I would suggest 8mm or larger for the best effect. This works best in lightly saturated materials. Cut in refractive indexes 1.62 to 2.14 with no changes.

Note: On the cut stone in the picture, I elected to omit the P3 split facets… My stone was smaller and I felt there was plenty of sparkle with out the extra facets and the piece I cut was a bicolor so I did not want the extra facets to mix all the colors.

This design cuts a very lively, brilliant stone and it's both fast and interesting to cut. This design is great for faceters of about any experience level and I think will become a favorite of many people that cut it.

Enjoy cutting your "Round Brilliant Dome #2″… Drop me an email to let me know your results and what you've cut, or feel free to inquire if you have any questions or need some help regarding this design.
