Old Euro Solitaire? Dating?

[MagnusMagnus]

Hello all,
I have just bought this ring at auction and interested to try and figure out when it may have been made. 18ct yellow gold ring. Stone listed as Old European Diamond, 1.38ct, Colour J, SI2 (estimated), extra thick girdle.
Only stamp indicates 18ct gold. Would be very grateful for any thoughts or input. I'm based in Australia.

Try to take closer up photos including of the faceting, close up to the crown, and of the hallmark. On a sunny day but in the shade typically works well for diamond photos. Try to have the diamond and ring come close to filling the frame.

It's clearly a Victorian look but the diamond doesn't look like it has Victorian faceting in your photo so I'm wondering if it's a later emulation or if that's the photography. Hopefully a real expert weighs in soon!

I'm not an expert by any means haha so take this with a grain of salt. The faceting is not old but more towards a modern round cut. So I'm going to guess it's from around 1940-1950 ish. Does it need resizing? A jeweller will be able to tell you roughly when it was made.

It is not an old European cut. Could be an early modern brilliant or just a modern brilliant. The cut of the stone doesn’t match the style of the era of the setting but I can’t tell how old it is. Could be from the 30s or 40s and reproducing a Victorian style.

Old European cuts can vary widely. I have a diamond that’s a family heirloom which one jeweler proclaimed to be a transitional diamond - but it has a tiny culet, which puts it in the OEC category. It was likely cut in the mid to late 1920’s, which generally also puts it in the OEC category.

A good jeweler would be able to identify the cut and relative age for you.

The presence or absence of a culet isn’t a distinguishing feature of OEC vs transitional. The latter is not technically a category of cut per GIA anyway. It is just a lay term we use for stones that are transitioning from OEC to modern RB proportions. So transitionals usually show a mix of features. Most diamonds that we could call transitionals in these boards have open culets. Mine does. Stones without might be called later transitionals if they also had other OEC features, like short lower halves or a high crown and very small table, but otherwise those would be called early modern brilliants by many. But the OPs stone has long splintery facets and a medium sized table. Even if it has a tiny open culet, I would hesitate to call it a transitional. Early modern brilliant might fit if it is antique. It’s not possible to tell if it is or not.
