Choose by outline
Which antique cut feels like yours?
Quality is not the deciding factor. Start with the silhouette, then compare how the setting changes the finished ring.
Choose Old Mine
For a cushion-like antique silhouette
The squarish outline makes its antique geometry visible at a glance. It works especially well in solitaire, bezel and three-stone settings.
Choose Old European
For a round outline with antique facets
The round outline feels familiar from a distance; its open culet and broad facets reveal the antique character up close.
Product truth
Antique cut. Modern origin.
Sula’s Old Mine and Old European engagement rings use newly produced laboratory-grown center diamonds cut in antique styles. Confirm the selected stone’s grades, report, metal and current configuration. We do not present these rings as salvaged or period antiques.
The Old Mine cut wears its history more visibly through its cushion outline. The Old European cut is quieter: its round silhouette feels familiar until the broad facets and open culet appear up close.
Common questions
Old Mine vs Old European
What is the difference between an old mine cut and an old European cut?
Sula uses old mine for a cushion-like outline and old European for a round outline. Both are cut-style descriptions for newly produced laboratory-grown diamonds; confirm the exact proportions and report of the selected stone.
Are Sula old mine and old European stones period antiques?
No. Sula uses these names as cut-style descriptions for newly produced laboratory-grown diamonds. They refer to the intended outline and facet character, not to period provenance.
Which sparkles more?
The category name does not determine light performance. Compare the selected stone video, measurements, facet pattern and grading report.
Should I choose an old mine cut or an old European cut for an engagement ring?
Choose the old mine cut for a cushion-like antique silhouette with visible geometry. Choose the old European cut for a round outline whose antique facets reveal themselves up close. The decision is outline and feel, not quality.
Can I get either one lab-grown?
Yes. Sula offers newly produced laboratory-grown diamonds cut in both antique styles. Confirm the selected stone’s grades, report, metal and current configuration; these are not salvaged period stones.
