Thanks....A huge amount of time to cut the pavilion. I was glad to get this gem completed.

Thanks Karl...It's nice to facet gems that you find. Seems to have more personal value.

Thank you...

@Dfg Sdfg For some reason I am attracted to gemstones with large windows, is it just me, or anyone else?

@Dfg Sdfg No worries, I was not being sarcastic. I honestly sometimes just like to be able to see through the stone and see it's real beauty as opposed to just all the Brilliance and reflections of facets cut at the correct angles.

Yes it is slightly windowed. I will do a recut sometime of this again. Maybe in another type of material. The refractive index is low in quartz so it was cut below the critical angle. But I was following the angles as near to the original design, as I've always been fascinated with the history and origin of such famous gems. Next time I will do 16 facets per tier.

@@VintageTimeGems I was not being critical, I like the windowwing!

Thanks...

LOL....Yes Ray. Jaws is a good watch dog.

It took over a week to complete this gem. I'd say 25 hours. The pavilion took ages.

Hi Clement, A gem like this takes about 30 hrs to facet....Cheers Cliff

No, rose quartzes are pink! They also have a hardness of 10!

I'm really not that sure. I like to use the slow speed these days. At a guess I'd say between 500 and 750 rpm. I'd say top speed 1000 to 1200 rpm.

Thanks Cliff. I have a tool for measuring the RPM so I will check the speeds on my VJ machine. I have a feeling that I am running too fast at times. I make a hell of a mess with spray LOL

Thanks....

Yes, it's a metal lap made of Tin.

No lap has has to be cleaned and reloaded with diamond grit. At least once for each tier of 24 facets....

@@VintageTimeGems Excellent, thanks for the reply.

Thank you Cristian.

I don't see why not. I come across synth ruby I certainly would facet it. It should facet exactly the same as synth sapphire and I've faceted that.

Gem dealers sell them, or you can make your own.

Any specific or just normal perspec can be use?

@@mezzan9032 Just normal perspex.

@@VintageTimeGems thank you so much

Actually this type of a cut is the least wasteful of most designs as you are actually cutting around the outline of the gem. Most diamonds cut in the 18th century and before were only cut for weight. These days they are cut for brilliance, so far more rough material is wasted. Also, I wanted to see what such a design would look like from a historical point of view.

@@VintageTimeGems Thank you for the explanation. I very much enjoy your videos.

Vintage Time Does this cut have a name? I’m on my phone watching this. So if there are any posted comments from you on it I can’t see any. But I thought what a sparkling yes safe cut this would be for a large gem. Since their such easy targets to damage because of their size. A lower crown might be safer set in a semi bezel set. 🤷🏻‍♀️

@@gigisdiamonds This design was just called the " The Great Mogul" got the design from a member of a gem club some time ago.

@@VintageTimeGems I have been looking for this design for a very long time. I have absolutely failed in that attempt. Where can I find a copy of this design? I have a lot of quartz that I collected myself and really want to attempt this design myself after seeing your wonderful work with it.
