You can find cutting instructions for Sonoran Snowflake here.
You need to watch for a few things that are a little different when cutting this design.
The P8s are basically a step cut, and cut in after the P3 and P4 steps are cut. If you want, you can rough in the P8 facets earlier to help get the tier sizes right. However, all of the tiers on the steps can vary somewhat. Your snowflake will look a little different. Then again, aren’t all snowflakes different?
The table is very large so that the snowflake shows through it. However, it can be hard to polish.
Frosting the Sonoran Snowflake
There are several ways to frost this pattern. I like it on the P3, P4, and P10 facets. If you’re cutting quartz, raise the angle on the P10 facets to 40.7. Cut everything else as is. This design is very nice and bright in quartz and beryl. Topaz is a little livelier because of its higher refractive index.
In the gemstone samples in the photo, the quartz is all polished with no frosting. The blue topaz is frosted on the P11, P6, P4, and P10 facets.
Enjoy cutting your “Sonoran Snowflake.”
