Fancy Colored Diamond Collection

[cflutist]

Love your collection Kenny.
Anything new in the works?

Resurrecting this thread! Such a deliciously beautiful collection! I got my first FCD in December (have wanted one for 7 years)- a very impulsive Levian .4 cr yellow diamond ring. It just made me want another. So that's how I found Leibish. I debated on a 2ct yellow pear but just fell in love with the pinks and just got my very first pink ring today from them in the mail, a .41 ct FIOP. I'm in love but I think I have Kenny fever cause I am thinking of what I want next once this is paid off lol! These beauties are just so stunning and they are all different, it's hard not to just want more! I love what your are doing Kenny and the photos are stunning! My faves of yours are the deep pink emerald, the green-yellow radiant, and the green-blue pear! I already have a ring idea that I want to get pink, blue, and green to put into based on a new ring Leibish just posted. I hope you've added more and continue with the photos, they are mesmerizing and have kept me up till al,PST 2am here!

They are and I'm with you on the money tree! I'll be paying this one for the next 10 months so must resist the urge to buy more till its paid!

What a spectacular collection Kenny! Thank you for sharing them with us!

I love my windowing Fancy Intense Orangy-Pink I1 heart just because the unique and fresh color makes my heart sing.
If it was an asscher with good light performance and that color I'd be over the moon in love.

Not forgotten !

Resurrecting this thread...Kenny are there any new additions to your amazing collection?

 

[kenny]

Thanks La2020.
No newbies.

But I do have better camera gear now.
Too bad I have less time these days, and my approach to gem macrophotography is so time consuming.

@kenny And other FCD junkies:

This is an easy to use tool to check and compare fluorescence and phosphorescence. There is an app for your cell phone so you can take pics.
It is around 200 Dollar.

Gemetrix Products

product description for a device (PL-inspector) to distinguish between natural and synthetic diamonds

www.gemetrix.com.au

To check phosphorescence best is a dark room and close your eyes a few seconds before you turn of the UV.

This is an example how it look like. You can take screenshots.

With a powerbank and an adapter you can use it to check diamonds in a gem show if you want to pic from a lot without reports.



The Diamond is a greenish brownish yellow mix color with strong fluorescence - not sure whether HPHT treated. A cheap EBay purchase.

I'd like to see what you can do with your new, fancy ooh-la-la equipment. Spam away!

 

[acebruin]

@Nosean the pl inspector itself is 200$? what does the app do?

The app helps to see the reaction. You can takes pics LW and SW and compare them with the slider. And your eyes are protected. I don’t know whether the lens is safe. Will contact the vendor course my camera is not able to show the phosphorescence of my diamond with phosphorescence.

@kenny , WOW. I hadn’t seen this thread until just now and I am blown away by your collection of FCDs. They are beyond stunning. Thank you for taking the time to share them with us.

 

[Polabowla]

This collection is so beautiful!

 

[kenny]

Thanks all.

When is that green oec gonna make its way into a killer ring?!

Seriously enviable and gorgeous collection.

Haha I only own 2 fancy colors and one is gray which isn’t really a color.

 

[kenny]

Thanks MTG.
But I'm more of a collector of loose FCDs, than someone who wants more than one ring to wear.

When I want to wear a ring, it's my Octavia.
Never say never, but I doubt I'd ever wear more than one ring at a time or want a selection.

Frankly (for totally different reasons) I love my Octavia and my Green OEC about equally.
I just can't see myself pulling a DF, and selling the Octavia.

Sorry.

 

[kenny]

You do realize that these are some of the most rare and precious gems ever posted on PS, especially that red guy at the bottom. Very impressive collection, and I rarely say this here, but a great investment.

Hello all.
Now it's 13 years later ...

@TL, Kudos to you TL.
You've proven to be quite the astute prophet.

About a dozen years ago I bought that 10-point GIA (VS1) Fancy Red Radiant diamond from Leibish with its nice even and clean pure stoplight-red hue for $36K.

Today Leibish is listing a 10-point GIA (SI2) Fancy Red Pear diamond with many dark areas and the hue below, to which GIA also gave the same GIA Fancy Red grade.
Price: $64K.

Both pics below are unaltered screen captures from Leibish's website.
The apparent size difference of the stones is not real.
It's just different enlargements of the images that Leibish happened to upload.
I did not bother resizing them.

Note the parenthesis around the clarity grades above.
GIA itself does not issue clarity grades on FCDs of this weight.
The clarity grades Leibish published for both Reds are from their GIA Graduate Gemologist, Shmulik Polnauer, one of the sons of the owner, Leibish Polnauer.

Here's a GIA piece about Shmulik: https://www.gia.edu/gia-news-research-alumni-shmulik-polnauer-fancy-diamonds

Considering my advanced age and medical conditions it might be the time to sell "Kenny's Big Red".

 

[RRfromR]

Those are so $$$$$$. I have a miniscule one in an antique ring and it was an accidental buy - I had no idea it's a colored diamond until I got it.

Saw a link to this thread and am so happy to have found it. Beautiful collection!

Thanks, all.

Does anyone know why violet does not photograph?
That pear looks pure gray in the pic but has a distinct, lovely, though delicate, violet hue in person.
The white balance of the pic is not to blame.

The light source was soft and diffuse.
What could explain this?

Maybe some violet diamonds are color-change stones like chameleon diamonds and alexandrite? The following quote discusses violet-grey, not grey-violet, but as many people have commented, GIA color labels are not always exact.

https://www.gia.edu/gems-gemology/summer-2018-natural-color-blue-gray-violet-diamonds

“The two absorption bands in these diamonds create two transmission windows (again, see figure 6). This can result in a color shift under two different light sources. This phenomenon is most associated with alexandrite, and occasionally seen in natural diamonds (Liu et al., 199 and treated diamonds (Eaton-Magaña, 2016).”

Another possibility is that if violet hues are caused by changes in lattice structure (with or without trace elements), then maybe the violet color that our eyes are seeing comes from light reflected at just the right angle and received via binocular vision. Or like how you see rainbows in computer screens when you wear polarized sunglasses. A camera might not capture it.

David Klass[‘s photographer] did a pretty good job capturing the violet in this dark violet-grey:


Whatever the cause, it might explain the lack of treated and/or lab grown violet diamonds. As a fellow violet lover, I am hoping that someday we will unlock the secret behind the violet hue and then be able to manufacture it. Pink LGD are getting purplier and purplier so there is hope.

Maybe some violet diamonds are color-change stones like chameleon diamonds and alexandrite?

Different camera (or phone) sensors respond differently to different color inputs. It's a function of the filters at each pixel (analogous to our different cones for color vision) and, presumably, the algorithm that combines and weights those inputs into the merged output image we see. I think many (all?) modern sensors struggle with violet. You could certainly design a camera (sensor + software) that does a great job with the shortest end of the visible-light spectrum -- but most users instead prioritize blue skies, green foliage, and peach/brown skin-tones so that is what the market delivers.

Is it just me, but that pear looks brownish. I think it’s ugly. Your radiant is beautiful and bright, no brown. Good luck with selling it, but I think it should be worth more retail than that pear.

 

[kenny]

Thanks @T L .

 

[jordyonbass]

Your radiant is waaaay nice than that stone @kenny and I would suggest hanging onto it for longer if you can, the value is only going to go further and further up based off the cost of that pear.

 

[kenny]

Thanks Jordy.
