Is this an Old Mine Cut?

[swingirl]

Can anyone tell me if this in an Old Mine Cut? It''s being sold as an OMC but looks like an Old European Cut to me. And what are those dots around the center?

Any comments would be helpful. Thanks.

I think OMCs were more square...a "pillow" shape. Also, that is the Kozibe effect!!! And I LOVE it!!

ETA: I am not sure I have seen it so pronounced before....so I do not know what affect that would have on the stone, hopefully someone will chime in.

Looks like an OEC to me. Old mines are more pillow or cushion like usually...

Looks like an OMC to me. If you tilt the view to the side, you can see the outline is somewhat cushion-y. The open culet is reflected all over the stone and this is known as the kozibe effect. Old cut lovers go crazy over this. It isn''t as noticeable in OECs but more obvious in OMCs.

Did she relist it? I can tell you she''s very firm on price. The GG that did the appraisal says it''s a mine cut.

 

[swingirl]

Is that to say the Kozibe effect is desirable? I agree, it's too round to be an OMC.

perfectpear, it sounds like you are familiar with this stone. Has it been for sale and around for a while?

 

[chrono]

Yes, the kozibe effect is desirable. I don't know, my eyes do not see it as round. It is the way it was set that makes it appear rounder than it really is. It looks as if the stone was set at a 45 degree angle with the (not so) pointy corners sticking out in between where the prongs are.

I made several high offers, the seller wouldn''t budge. It''s been for sale for at least once before. I didn''t want to pay the asking since the girdle is clearly abraded and the current setting is worthless.

It looks OM-like, but I wonder if it isn''t either an authentic, antique OM that has been repolished, or a modern cut polished to look like an OM. What I''m trying to say is, it looks like a "tarted up" OM...if that makes any sense.

I wonder if you can get a shot of the side profile. Looks like a really teeny table. If I tilt my head 45 degrees to the left, it looks more pillowy than round.

 

[Hest88]

It doesn''t look pillowy to me, but it''s clearly lopsided and not perfectly round. The non-pillowy effect may just be from the photograph. There seems to be such a sharp outline around the girdle, but the bottom is pointier and if you look on the right side you can see how it''s not a perfect half-circle.

I am guessing that the value goes down when any of the old cuts are tampered with?

What would scuffed up the girdle? Certainly not regular wear. Any thoughts?

I agree. When I cocked my head, it looks like an OMC to me too.

I was thinking the same thing.
Thats not the orginal setting for the stone so its been reset atleast once.

 

[innerkitten]

I saw this listing too and wondered the same thing. It didn't seem like a bad price really if it's a good qualiy stone. But i idn't think t looked like an old mine cut eiher. You think it's been altered?

 

[beaujolais]

Anyone want to say what site it''s from? Asking only as I love looking at the sites with old stones.

I hope it wasn''t fidgeted with, however I get a funny feeling regarding this. Otherwise, it''s very cute. Great kozibe effect.

To me it is a bit of a lob-sided OEC!
Probably from the end of the 19th. Century...

All 8 mains look pretty even to me in size..., just the outline is a bit lob-sided..., nice stone..., lots of character!

There you go an expert opinion from an older cut expert(diamond age not personal age! lol).
