What flavor is my heirloom OEC?

[glitterata]

Old-cut experts, how would you describe my OEC?

This is the diamond my grandfather gave my grandmother in an engagement ring sometime before their wedding in 1921. It's a K/L, SI2, about 1.65 ct. It lived in several settings in the family (a man's ring that Grandpa wore, a necklace Grandma gave me as a graduation present, a repro Edwardian ring setting after I got married) before I finally set it in an antique deco setting a few years ago. Of all my diamonds, including other OECs, transitional cuts, an OMC, and two CBIs, it's far and away my favorite. The cut is so beautiful. Every part of it is alive, no matter what the lighting.

What "flavor" would you call this cut?





And here it is in its previous setting, the repro edwardian:

I’m going to call it a transitional.
Based on the size of the table, crown height, I can see arrows and my inital gut said tranny.

I’m going to guess GIA would call it an oec based on the size of the culet though…

Very pretty stone and I love the setting! Enjoy her!

Thank you, Lavender!

For what it's worth, the appraiser recommended by David Atlas called it an OEC when I had it appraised 20-some years ago. (He called my other grandmother's diamond, from 1929, a transitional.)

@Dreamer_D, do you have an opinion about this diamond's cut flavor?

Depends on who you ask!
Id just call it an OEC.
lgf% is too long to be a classic oec but are shorter than modern RB
IE smaller arrows/mains than oec larger arrows/mains than mrb.
OEC style crown not sawed large like what most consider transitional.
GIA probably circular round brilliant.

Do the pavilion mains drive light return in the modern round brilliant?

Thanks, Karl!

If I someone were looking for a similar look, what specs should they look for?

small table high crown then look at pics for lower configuration(arrows).

Late OEC, early transitional. The latter isn’t a cut designation which is why you likely won’t see anyone calling it that. You said it’s from the early 1920s and that’s basically what I’d expect then as they were just starting to transition to newer cut styles. So it’s a mix!

To find similar you’d want a slightly larger table and shallower crown and longer lgfs than you typically see, but non as large/shallow/long as you see with MRB. And a realively high degree of optical symmmetry though yours is still fairly chaotic compared to some later transitional.

My vote is late OEC, too. So pretty!
