That''s because I can''t figure out what size to target. I''d like it to be able to stand on its own, without overshadowing my e-ring.

 

[arjunajane]

Yes, very bad influence..

Chrono, if I can one just another Q -
do you know what the spread is like for these? As in, if an H&A RB has the largest face-up appearance, and a princess smaller, where about''s do these cushions lie in weight vs face up spread?

of course if you can''t answer don''t worry I can always email
Jon, I just thought you may know (Or stephanie too if you know?)... Thankyou!

 

[chrono]

My apologies to those who hate math but I’m indulging in my favourite subject.

AJ,
My guess is that they are very close in face up size. Here’s how I calculate it:

1 ct RB: 6.5 mm
Surface area formula = 0.25 x 3.14 x 6.5 x 6.5 = 33 mm square

1 ct OMC: 5.90 mm thereabouts based on my OMC2 which is 1.07ct and measures 6.16 x 5.91
Surface area formula = 5.9 x 5.9 = 35 mm square

Of course there will be small variations between stones but for the most part, I’d say the face up size ends up quite close. What is misleading is the depth. RBs have a depth of 62% and OMCs have a depth of 68% and apparent diameter length. However because of the round shape and corners, the total surface area is actually about the same.

 

[arjunajane]

Arhh! Miss Chrono, brains and great taste! lol..

You''re a champ my dear, thankyou very much for taking the time to explain.

You are very good at this math business - me..hrmm..not so much

But your explanation was clear enough for even I to follow, so thankyou!

And good news too!

(oh, btw - you and Stephanie need not worry - I am not shopping in the same size range
as you girls - so no competition from lil ''ol me)

Hey C, just a clarification - with this last bit, are you saying that the cushion with the square corners,
the eye perceives as larger than a round shape - so than the difference in depth kinda "evens out"..?

Please correct if I'm way off!
Sorry if I'm sounding dumb, just want to make sure I'm understanding you right
Cheers matey!

Oh I''m not worried! I just would have laid claim to that beautiful James Meyer (I think thats who made it correct...?) bezel setting that you have in your avatar

LOL! Its okay though! Jonathan has already sourced my rough for me! Besides! The more the merrier! My cushion needs some friends to hang out with! And who better than those who have GREAT taste?!?!?! I''m thrilled that my idea is leading others to beautiful cushions as well! To be honest...when I shot Jon an email asking for certain size/color/clarity...I wasnts sure what he''s say! Thankfully it was a YES and now I''m getting my dream stone (well...for now

LOL)

If it wasnt for poster like you I NEVER would have thought to ask, let alone found GOG or even KNOWN WHAT A OMC IS!??!


BTW...I''m watching out for a vintage watch for my wedding gift now...

I didnt get one for myself for my b-day...but you guys are naughty and I cant get one off my mind! I''m hoping the one I have my eye one says in budget and can be serviced in time to wear with my wedding dress!

I meant that the brain perceives on paper that a 6.5 mm RB will appear larger than a 6.0 mm cushion when in actuality, they are the same face up size. This is because the 6.5 mm is round aka no corners whereas the 6.0 mm cushion has “extended” corners. This point is proven by the surface area calculation. Does that make sense?

 

[Dreamer_D]

I am very jealous of you all! I want an "old cut" stone, and a new cut one is a great option!

Once I have reached my desried size for my RB I will move on to other diamond shapes in more modest size -- ie. under 1ct. And one of thse cushions from Jon may be the first purchase!

And may I say, Charmypoo, you avi is KILLING ME! Do you own three maltese? Or are those malitpoos?

Hi Chrono

If you are talking about a comparison of "face up" size, then what you really want to compare is the lateral surface of each, and not the surface area.

 

[Harriet]

Hey, math whiz, so what size should I target?

Whatever size pleases you. I always encourage everyone to go as large as the budget will stretch.

Were you expecting a different answer?

 

[Harriet]

Yes, goondu.

Sorry to disappoint. I have to maintain my reputation as an enabler.

Hi Chrono, thanks for the info. Do you know where I can see the GOG signature OMC facet pattern? And is there an open culet in the signature faceting?

You can see it in the ''Chunk in the Trunk'' video where all 4 OMCs have exactly the same faceting pattern. The culet is large per GIA grading. It is also observable in the video. I think what I called OMC2 (1.07 ct G VS2 cushion) is back on his website. If he''s updated the picture, you should also be able to see a static picture of the facet pattern.

I''ll take a look at that (and I note you say the cutlet is large per GIA grading). The one thing I didn''t like about the original prototype is the cutlet was too small for me. That would be a deal breaker. It''s not all about "the light return." If I want that, I can get it in a RB. Thanks for the information.

 

[Kasey3]

Harriet-what type of setting are you going to put it in? If it is not going into a halo I would get at least 2.5. I have a 2.38RB and I purchased a 2.36 J old style cushion from Jon with a 1;16 ratio. If I turn it EW I am happy with the size compared to my RB, when it''s NS, I am not. The dimensions are 7.36x8.6 if that helps. I was going to upgrade that stone to a 2.5 H, ( I have some color issues with the J) but the difference between the 2 stones was not worth the amount of $ to upgrade-so now I am waiting to see Jon''s new stones when they come back from GIA and if I like what I see I will also be ordering one-probably with a desired l\w around 8 because I am going to put it in a Leon halo to add the size I want.

Since you are so close, and Jon has so many cushions in so many sizes and shapes, why don''t you hop on the LIRR and try some on!

Hi Kasey.
I am interested in hearing more about your comparison between your RB and cushion, if possible (above I was
grilling Chrono on this topic

)..

Do you mind to state what mm your RB is, and is it an H&A/ideal cut?
Do you by any chance have a pic of the cushion you could share? Also, you said you weren''t content with
the colour, but are you impressed with the performance/appearance?
Are you able to describe how the cushion stands up next to your RB?

I am just trying to get some ideas of what these L/W ratio actually look like IRL, and of course these
cushions when compared to my H&A RB ..I hope you don''t mind all the questions!
Would appreciate it if you have the time.

with thanks
aj.

Yep, that was my understanding of your initial comments. I believe we are saying the same thing, only in different ways.

Thanks C!

Lol, thankyou Stephanie for the compliments -
oh, and you will have to fight me pretty good for my Jim Meyer hon!

Yes, I agree it is a great thing that Jon is doing "diamonds to order" like this - I believe that was very much
where his business was heading, at least when it comes to us particular Ps''ers

But seriously, it makes sense and is a great service, and in my perception it is a win-win for both vendor and buyer.
I do hope that others consider adding this type of service to their sites too.

Anytime!

I shoot jonathan an email because I was just wondering what range of my size/color/carity they had found rough for. He emailed me back saying there was a one in particualr that was looking to be 1.5-1.4 carats, J/K/L

in color, and VS2 in clarity...but there was another one that was 1.3-1.4 carats H/I/J in color and SI in clarity.

I LOVE OMC''s, esp. the new ones...if the first one comes back as K or L in color...is that going to be okay for my e-ring

I was hoping to get size by going down to J in color...but not as far as K or L.

I''m hoping what happends is both stones come is graded J in color, and 1.5

That would be the PERFECT stone! However...I''m not sure a J VS2 was in my budget

but Jonathan knows what that is...so I''m sure he wouldnt tell me something if I cant afford it

Do you think it would be okay to have a K or L colored OMC? Eventually I''d like to put it in a vintage type setting...and a hint of warmth from the side would be okay as long as it faces up white. Opinions?

 

[arjunajane]

stephanie, you''re asking the wrong person hon!
I am a "warmer colour fan girl" - my current ering is a K SI1 , 1.25ct Isee2 RB,and I love it. Love the K, wouldn''t have it another way - lol..

And with the cushions, I''ve infact requested the J-M range - that would be ideal for me.
I''m aware that colour will likely "show" a lil more in the cushions than in ideal RB''s, however I also
believe that in older style diamonds, the warmth is more complementary.

Infact, if you look through the inventory of say Erica Grace, most of their finest vintage diamonds are in that
range - and they look incredible!

So, at the end of the day it is of course personal preference and what your budget will allow.
My personal "sweet spot" is K, SI1 - but I will happily go down to an M.

This is Erica''s new 3.64 M VS2 ring'', and its killer - I''ve seen photos on the hand too, and its gorgeous! doesn''t look yellow at all (if that''s what you''re worried about).
(hope you don''t mind E!).

Holy COW! I want a ring like this! But with pear sidestones! WHO MADE THAT!?!?!?!?!?!?! I NEED ONE!!! I WANT A LOWER COLOR NOW TOO!

Jon! Make it an M and a 2carat one at that! LOL!

 

[arjunajane]

sorry, I just wanted to add after re-reading your post -
remember Jon will be giving you a range like that (ie. J/K/L) - as grading is still so subjective, so I'm sure
he doesn't want to promise you a J but the lab sends it back an L, kwim?

However, it is entirely possible that both will come back as J's.
Thats just the way grading goes

seriously, I wouldn't worry about it.
Jon knows what he's doing.

ETA. I know right, isn't Erica's ring fantastic? Here is the link about who made it, I believe it is SS, who I know you like -
you can commission a similiar piece

get inspired

 

[arjunajane]

here's the incredible profile view with the FDL cut-outs..
I could certainly be tempted by a ring like this !
(I hope others don't mind, I thought this was relevant to the thread topic).
