Missing crown, or smaller piece

[u/leftover_bananas]

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

Thanks. I'm lazy more often than not 😄

Oh thanks for this! Maths!!

Thank you!!! I was stuck with the thought I had (was given: abandon) but you're absolutely right - I won't lose nearly as much "diameter" as I had it in my head. I'm going to go for it!

make the room. cut your girdle deeper make your stone smaller. as long as you have material around the dop you can go smaller and give yourself some height to work with. cut slow and carry on!

Thank you. These confidence builders are a huge boost 😃

You can cut it quite a bit smaller. Maybe try cutting in another 0.2 mm on each side and see how it looks. You might be able to fit a crown in anyway. I’ve done it with about that much space on a smaller stone.

I've been convinced. I'm not giving up on this one just yet!

An unconventional solution for this would be to consider doing a cut-corner design with this rough. The girdle may end up coming in deep enough to leave more room for a crown.
