Old European cut vs transitional cut the same thing?

I am just curious. Is the only difference in the cutlet?4D989AB5-067A-4275-8294-F70B918835C4.jpeg

No, there are many proportional differences. Transitional means anything between old European and modern round brilliant. In any case, transitional diamonds have a culet (like an old European) and a larger table than old European cut. They also have longer lower girdle facets than an old European. There are some beautiful transitional diamonds, but it is very common for the term to be used on badly cut early modern round brilliant stones.
 
I find this visual and the article it came from by Grace Navarro are useful to illustrate the difference…

Though the image of the old mine and antique cushion don't seem that accurate to my untrained eye.

Transitionals can have more of a checkerboard appearance than OECs.

The chart is not accurate. That is not a tranny; it is just a badly cut MRB with deep pavilion and relatively skinny arrows from 80% Lgh.
 
Here’s a better pic of a transitional

There’s no hard and fast set of ratios for a Tranny as has been said. They started out as less flowery OECs and ended up as flowery round moderns, that’s the best way I can describe the evolution. The range of what vendors call transitional cuts is a hot mess, all over the shop, etc. but I love them and have 3 of them.

The first one is very flowery, credit to David Klass for the photo. It’s a 7.8MM 1.29 carat. Broad and pretty flat, but has some table top definition. It’s the most pure of mine.

The second is a CIA circular brillant, just off the OEC guidelines but it looks the most like an OEC. Anyone but the GIA would call it an OEC but the depth is off by 1%; hence she was a bargain. She’s a D and bright as hell, hard to to photograph.

The third is a hot mess and most to my eye like a not well cut modern. The facets are much more like splinters but still has the open culet. The top is FLAT, pancake flat. The girdle is thin like in older cuts and frosted. It’s probably the oldest but was just cut roughly but it works in this ring for some crazy reason.

I have a transitiona 1.5ct solitaire that is mesmerising, really checkerboard. i love it, but not for everyone! Apologies I have a poor camera.8E830CB2-9A34-4C03-A973-F3EE477202E7.jpeg8DBA2D58-1280-47F1-904C-2D99693A8D22.jpeg82945208-738E-4BD9-BAB7-22C78CB72228.jpegBCAD6027-FC04-4477-BF68-2F30B6158A32.jpeg86B33164-BAEB-4897-966D-6A53B3130D25.jpeg6B437C16-8DF8-49B7-896A-CA66E7C39903.jpeg
 
They’re all beautiful in their own right! I’d love one from each cutting period.

I have a few round brilliants, an OMC 1.61 ct and the transitional, I only really wear the OMC and the transitional!
 
I always thought this one of mine was a tranny. Here's the info from the cert and a couple of photos. Can someone confirm my thoughts?

Beautiful! It’s interesting…I would’ve described this as an OEC with a checkerboard pattern, but what do I know?

Probably what I know:???:. Sometimes I see a flower pattern and sometimes I see a checkerboard which is why I'm asking for feedback. Thanks for yours. I think it jives with the reality of looking at the stone.

Your stone is just drop-dead gorgeous. I can see checkerboard in one picture and a flower in another. It is drool-worthy!

Thank you. You know it's funny. I really don't wear this ring often as I put it in a temp setting and never figured out what to do with it. I've never looks at the actual proportions on the cert until today. The 55% lower half kind of surprised me. But I love my stone, just need to find a setting I love as well. I'd still like to know what to call it, though. And again, sometimes it looks like a tranny, and then sometimes an OEC.
 
For me, better symmetry, a tiny culet, and a table that's close to the depth percent, or perhaps larger than the depth percent, usually under 60%, plus short lower halves (i.e. in contrast to early MRBs with longer lower halves) makes a "transitional." In contrast, OECs have "ring-pop" proportions, with big puffy crowns, variable symmetry, and a variable, but usually medium or larger, culet. (edited to add: because of the crown floof, OEC = table considerably smaller than depth!)

I call both of these stones "transitional," although the ruby-halo one was sold to me as an OEC. I don't have proportions on it, although the crown is not high and the table is relatively large. The platinum bezel one was from Adam at OWD and he described it as "transitional," with a depth and table % in the mid to upper 50s. They both have very small culets and good symmetry (hence, the arrows - it is really hard to get them both to line up simultaneously so you might have to trust me on that! ;-) ). Note the pronounced lack of crown poof!

Love both those settings, especially the super low second one.
 
Not to threadjack, but it's from I&R; thank you! :) I love low bezel settings -- and yanking the conversation back on track -- it's also partly why I love transitionals! Can't get a stone with 65% depth as low as you can a stone with 55%. :mrgreen:

Hey that’s a good point!
