It's a while since I did any faceting so I just entered this into Gemcut studio, it looks to be a fairly dead cut so I twiddled with the angles, the crown angles didn't have much of an effect, but by dropping the P1 angle down to about 38.44, B1 66.75, B2 67.16, B3 67.82, B4 68.21, B5 68.34 it should be a much brighter stone. the iris is still dark so the eye effect isn't lost.
my 2cents worth.

See if this works.

A bit of advice, make sure your machine is accurate and your polishing laps are flat and running true, if they're not, don't even think about trying to cut this.

It fairly challenging even when you're laps are true.

I find getting the transfer exactly spot on is also very important that is why I'm now using dop clamps not the gemmasta V grove.

I'll have a go at this one, but with a bit of glass first, I like to pick something a bit harder.
By the way MakkyBrown, I'm cutting Stargazing out of your book, using smoky Quatz at the moment

Cheers

That's exactly what I'm doing, too!, just about to start P2.

I have only cut it in topaz. Hopefully it has enough power for the smoky given the L/W. Looking forward to the results.  If you colour the stone in with black texta before cutting P2, it makes it easy to see the preform facets being cut away.

Have cut it in Green Quatz  and has plenty of sparkle, just starting the polish on the pavilion with the smoky. Will put photos up when finished.

Cheers

It's an interesting design as it is asymmetrical on the pavilion. Good to cut so far. My stone is more of a citrine than a smoky per se.

I find getting the transfer exactly spot on is also very important that is why I'm now using dop clamps not the gemmasta V grove.
What are dop clamps? Is this something you have devised?
My Facetron's transfer jig is pretty well made, but it still surprises me how much cheater I have to routinely apply post transfer before starting the crown. There has got to be a more accurate way.

No not my idea but I made myself(pictured) some nice ones with stainless thumbs screws. The hardest bit was drilling the holes for the screws/threads perfectly.If I was making a lot I'd made up an alignment jig for drilling.

Interesting. However I don't get how you would use this to transfer - if you had a dop in another clamp, how would you ensure they were on the same axis when gluing?

You set your hand piece at 96 with the cheater in the same position you started cutting the pav at, then clamp on the dop clamp with it's feet flat on your master lap. You then transfer with the clamp attached. After the glue is dry remove from transfer jig and put the new transfered dop into the hand piece collet with the feet on the dop clamp sitting level on the master lap then tighten.  Then swap the dop clamp to the new dop with feet level. Then you can remove the new dop from the collet to remove the old dop. And then put the new dop back in the collet/feet level on master lap, tighten, remove clamp.
I'm not very good at explaining :) hopefully you get the idea. Doesn't take long to do using the thumb screws.I do use the alignment groves aswell, this works as a back up if the super glue holding the first dop to the stone comes unstuck. But if all goes well the grove isn't needed and the dop clamps give a perfect transfer.

Ah, yes I get it now, I have seen something similar before in my travels come to think of it.

You all inspired me to start making eye designs. Got a bit out of hand and now have well over a hundred different versions of eyes scatter across my laptop and desktop. Some are really nice. I just cut this one in spinel. It's not too bad. Darken the rough a bit so best for lighter gem materials.  Was a bit tricky to photograph as the camera lens cast a bit of head shadow on the small table.I'll be releasing this in the free designs section on my webpage probably next week after I sequence it.
