The angles of the pavilion give this gem great scintillation, I live in the emerald world where the cut is to often sacrificed for size or color making a bunch of windowed stone to weed out to get to the good stuff, great job Bopie!
Hey Mike - it's Arya. The issue you're talking about with P4 is just a convention of how designs are written. The indices for any given tier are always listed in increasing order, even if (from a sequencing standpoint) it would make sense to do them in a different order. It's up to the faceter to recognize that.
Impressive! In an earlier video you were talking about how some gemcutters prefer clear incandescent bulbs and were going to see if you could notice a difference. Any news on that?
Yes. When I went from an frosted LED to a clear 100 watt incandescent bulb, I am able to spot scratches easier. One cutter recommended the "Chromolux" brand and I got one, it's pricey, but my 100 watt Chromolux incandescent works great...not a big difference with clear 100 watt incandescent bulbs, but maybe a little. What I can't say is what wattage is better. I use a 100 watt and a several gem cutters say a clear 40 watt incandescent is easier on their eyes and they still pick up more scratches. ...and watt isn't really what matters its the lumens or brightness, but most everyone just talks watts. So to me, yes, a clear incandescent bulb is better than a LED bulb...but the jury is still out on 100 w vs 40w or maybe even 60w as several other gem cutters use.
Quick question, does one need different laps for different gems to prevent cross contamination? Could you use a the same lap to cut cz's and other gemstones?
No, you don't need different laps for different gem material. If any gem material gets imbedded in any lap, you need to clean the lap and remove the imbedded material, regardless of what rough type you are cutting.
Along the same line ……. Do you use a different lap for different polishing compounds or do you just clean the lap? For example when going from 14000 diamond to 50000 or when going from 8000 diamond to cerium oxide or similar?
@@scottpolo688 Great question. Ive seen people use the copper lap and wipe the lap/investment clean before using a higher grit. I am a noob, so I would double check with the professional.
@@scottpolo688 I generally use a different lap for each polishing compound. I use a different Batt lap for each of the diamond grits I use, however, you can use both sides of a Batt lap and many cutters use one diamond grit on one side and another diamond grit on the other side. Other cutters will warn against using both sides as it is easier to get cross-contamination. In the case of the Darkside lap, I use different polishing compounds with this lap. I have used Cerium Oxide, Aluminum Oxide and 60,000 Grit Diamond on this lap and cleaned it between compounds with no problems. Also, I could never get my ceramic lap to work right, about 50% of the cutters who try this expensive lap, can't get it to work. However, I understand it is no problem to change compounds/grits on a ceramic...but again, I do not use the ceramic lap.

Thanks for that information!
That has a really nice sphene look .
Thank you. I have some Sphene in my 'to cut' box...I hope to cut it soon!
One of the most beautiful pear shapes I've ever seen! I want to try that.
Thank you!
WOW.. so beautiful zirconia... Master job.. Greetings from New York👌👌👌🇵🇱🇺🇲🗽
Thank you!
Beautiful work. I like the cuz, it makes a beautiful gem.

Where can I find these discs?
Is there an address to contact watsab? How much laps?
As in THE ARYA, That adjusted the original design?
I can't believe Jeff doesn't know one of his idol cutters watched and commented on his video....
Good luck mister! Hope you win! The cut makes the CZ look like a real gem!
Yes, the CZ turned out great.
Where can one buy CZ for faceting from, I have no clue where to start to look for it.
If you contact me on Facebook, I will be happy to help.
