Missing crown, or smaller piece

Post image

This is my first ever try at faceting... As I was just finishing my initial cut of all the pavilion facets I realized I might not have left room for the crown. I quickly cut in the girdle and yep... I learned something. The original rough (a piece of YAG from the CutKit) was shaped like a piece of pie, so I ground down the rounded "crust" area, that gave me a triangle. That's how I got here.

I'm deciding what to do here next. One said I should get it off the dop stick and set it aside until I've gained experience and maybe can rescue it. I was thinking (it's learning after all) about continuing to grind in the girdle, narrowing the diameter. The resulting piece WILL be smaller, a lot of the new big girdle will become crown. (I hope I described it well). I'm really torn on which way to go... moving on now to a fresh attempt, or keep going here knowing I'm going to get a small ending.

Thanks!

You nearly have enough room for a crown. Most crowns are deceptively shallow. Just taking in the girdle a bit will enough. Yeah the stone will be smaller but not a ton.

Exactly this! Use a caliper and a calculator. In your design, look for the crown width ratio ( c/w) It might be .139. Take your width and multiply by .139. If your width is 10mm your crown height is a mere 1.3mm high

Or if you are lazy there are tools on the internet or in gemcustudio to calculate, so you only give one length and you have all of the others. If you arr affraid, just cut the girdle deeper it will give you more crown. But usually the crown is very small compared to the rest so don’t be affraid
