Curious, a crown-less pear brilliant face-up pavilion view.

[diagem]

Hello all,

Just completed a test on a natural orange colored Diamond. I find the image intriguing and wanted to share.
Its an image showing a completed pear brilliant pavilion through a crown-less Diamond cut..., (e.g. a face up view showing how the pavilion of a brilliant cut pear will appear if there was only a table facet with no crown facets, ugf's or star facets.)

In the image: The Diamond placed in a (cemented) position in a special dop in order to cut the huge table facet

Enjoy...

It sort of reminds me of a rose cut diamond. This would be pretty set pavilion up.

I plan on cutting the crown portion now, but I agree that it does show up as an illusion of a type of Rose Cut.

Kewl stone Yoram!!

A profile view would really help with perspective- it's hard for me to tell which side of the stone is up in the picture

David..., you are right. I am under-estimating the power of Diamond's Optical Illusions...
Here is a (kinda) profile view of the Diamond on the polishing wheel...., there goes my illusion



A bit closer as well.

Cool...so that really thick girdle is going to turn into the crown? I love seeing partial steps and how things are done. When
you cut the crown is the table automatically there or do you have to do more "cutting" to get the table? I assuming that
whatever is left after you cut the crown is the table...probably wrong though .

Yes tyty333, you are right, the girdle thickness will turn into both the crown & table of this Diamond.
If the table facet will need more cutting will depend on its fissures, but it will need polishing for sure.

Fascinating thread Yoram. Even those of us that have been deeply involved in the industry for decades do not know the intricacies, considerations and complications of the work you do. It gives us all additional insight and appreciation for your craft. Thank you!

Can you give us more specs on this particular stone? What was the rough like, projected yields, predicted color/clarity etc.

I would assume that sacrificing crown fullness is a fairly easy compromise, even maybe preferable, for a saturated fancy color. Fire would be suppressed anyway due to body color and so is not a goal of the design. Not sure how a bigger crown would play with ray lengths to enhance or diminish aparent color (?).

Look forward to following this project!

Thank you for your kind words Bryan, I try to bring unique cutting process stories because this is my day to day working environment.
Cant give you exact specs from the top of my head as I have quite a few of these on the wheel at the moment, but I will attach two images showing the type of rough I utilize for these.





As you can see for yourself these Rough crystals are pretty saturated with color so darkening them is not the main issue here. Actually i am aiming towards cutting them to real old-charm visual appearances, just like cutters did in the old days. The pears will end up pretty flat thus loosing quite a lot of weight during the process, I would dare estimate an average yield of 25-35%.
I might not agree with you about the fire being suppressed simply because this facet design incorporates large chunky facets which have the ability to shoot out quite lovely flashes of colorful fire even on such saturated material..

Obviously I will attempt to prove this as they are completed. It will be hard with no videos.

Well I want one of those old charm light yellow stones that you are cutting! I'll just have a Yoram collection!

Re: Curious, a crown-less pear brilliant face-up pavilion vi

That's quite a bag of magic rocks you got there Yoram. They look good enough to eat! (and if you turned your back on the wrong person that actually might happen )

Seriously though, when you look at all those hues, shades and shapes, it is mind boggling how complicated it must be just to determine the best approach to cut design in order to maximize beauty and value. And then, like the current challenge with the feather parallel to the table, you have to factor in various clarity features, not to mention cleavage planes and polishing directions. And the cost of rough is so dear that mistakes in design OR execution can be financially disastrous.

You guys must have nerves of steel to go along with your talent and skill!

Great point Bryan- you would NOT want to play poker with Yoram

Seriously, I agree. When you think about some of the stones Yoram , and other cutters, work on- which can easily go into the millions of dollars.... You need those nerves of steel!

It's just beautiful. I love the whiskey color and that lovely flowery pavilion.
I wish I could have any one of those stones cut by you. Such a larbor of love. That profile view is really enlightening too. So cool. Thanks so much for sharing.

Re: Curious, a crown-less pear brilliant face-up pavilion vi

hmm if the crown was higher that would rock a checker board crown.

Thank you for such a compliment ds. Coming from you it means a lot.

Based on my life long experiences, you are 100% correct, how did you know?

Bryan, nerves of steel turn into softer nuances with life's experiences, you never get used to disastrous consequences but life definitely teaches you to take things thrown at you with perspectives.
In order to reach such high levels of skill in our industry one must learn from mistakes. I always say, if you learn from your mistakes then you will be on the right track. But if you don't...., put a helmet on

I am actually a terrible poker player..., the only poker I am willing to play is the old-school five card game. Texas Holdem is not for me...

Thank you Gypsy, actually the color we currently see (in the pics) are a bit misleading because of the dirt collected during the cutting process, in the face up image above one can clearly see all the dirt attached to the Diamond while it's being worked on. Only when completed we deep boil the Diamonds to get rid of all excessive dirt. Only then the true color reveals itself....

I leave checker board faceting to colored Gems. On Diamonds I would always prefer a rose cut type of crown....

Re: Curious, a crown-less pear brilliant face-up pavilion vi

Will you post a picture of the finished stone? I would love to see
How it turns out.

I'm loving those honey colored stones in the middle of your pic and the ones on the right had side. Beautiful mix of colors!

I had no idea. I hope you'll post pictures of the diamond throughout the process. I can't wait to watch this unfold. You are so talented.

Deep boil can I put my diamond rings in the kettle to clean them!

So fascinating! We would love to see more of the process! Even my DH who doesn't get my diamond obsession loves these types of threads! Thank you for sharing them with us!

Re: Curious, a crown-less pear brilliant face-up pavilion vi

What an amazing thread. It is so I intriguing to see the process. I wish I could own one of your beautiful stones....I would even take a little mistake!!! Can't wait to see the finished product.

Hi, thank you all for the feedback, I appreciate. I will definitely show how the progress evolves as I move forward.
Thank you,
