Old Cut Engagement Rings

Old cut engagement rings are shaped by hand, not by machine. Each stone carries broader facets, a higher crown, and proportions that were set by individual craftsmen, stone by stone.

At Carat Diamonds, every ring in this collection is available in two stone options: certified lab grown diamonds and moissanite. Both are cut to antique proportions and available in old mine cut and old european cut styles.

If you want a ring that does not look like everything else in a display case, this is where to start.

Old Cut Rings Available in Lab Grown Diamond and Moissanite

Old cut diamonds and moissanite stones in this style were both shaped before laser-guided machines standardised every angle. Each stone is cut individually, with broader facets, a deeper pavilion, and a high crown that handles light differently from a modern round brilliant.

Key characteristics of old cut stones:

Larger, open facets: light spreads across the stone in broad, soft patterns
High crown and deep pavilion: more weight sits below the girdle than in a modern cut
No two stones are identical; variation in geometry is the point, not a flaw
Open culet visible through the center, the defining detail of the old european cut

Both lab grown diamond and moissanite in this collection are cut to these same antique proportions. Browse the full old cut engagement rings and old cut moissanite engagement rings to see both options.

Old Mine Cut and Old European Cut

Both cuts sit within the old cut family, come from different periods, and have different outlines. Both are available in lab grown diamond and moissanite at Carat Diamonds.

Old Mine Cut

The earlier of the two, from the Georgian and early Victorian eras. Cushion-like, squarish outline, very high crown, small table facet. No two share the same proportions; each was shaped individually from rough stone.

Cushion-square outline, squarish from above
Very high crown, deep pavilion, small table
Works best in yellow or rose gold settings
Available in lab grown diamond and moissanite

Old European Cut

The latter of the two was prominent from the 1890s through the 1930s. The round outline is the direct predecessor to the modern round brilliant but retains the high crown, smaller table, and open culet of antique hand cutting.

Round outline, closer to a modern brilliant in shape
High crown and open culet, the characteristic centre eye
Works across yellow gold, white gold, and platinum
Available in lab grown diamond and moissanite

Both cuts are available together in our antique cut engagement rings collection, including the antique cut moissanite range.

Why Old Cut Rings Look Different

Modern brilliant-cut stones are engineered for maximum white light return in the fastest, sharpest way. The effect is consistent; every stone produces nearly the same pattern.

Old cut lab grown diamonds and moissanite operate differently. Their broader facets scatter light slowly, in wider patterns. Under soft indoor lighting or natural daylight, both produce a quality of light that is difficult to photograph accurately. Most buyers say the ring looks noticeably better in person than online.

The difference between the two stone types:

Lab grown diamond: produces white light return with natural fire chemically identical to a mined diamond, IGI or GIA certified
Moissanite: produces higher colour dispersion (fire) than diamond, with more visible colour movement across the face of the stone under light
Both are more interesting under soft indoor light than under camera flash

Best Settings for Old Cut Engagement Rings

Old cut stones have depth and volume that modern stones do not. The setting needs to work with that.

Solitaire rings with four or eight prongs, nothing interrupting the stone. The most direct pairing for both lab grown diamonds and old cut moissanite.
Halo rings work well when the halo edge is milgrained. Keeps the vintage character of the stone intact rather than modernizing it.
Pave bands shoulders with brilliance without pulling focus from the center stone. Works well for both stone types.
Vintage-inspired settings: milgrain edging, hand-engraved metalwork, or filigree. Extends the antique feel from the stone into the ring structure.

Metal pairings: yellow gold is the natural choice across both stone types in this cut. Rose gold works well for old mine cuts in warmer color grades. White gold or platinum creates a deliberate contrast between antique stone and a clean modern band

Frequently Asked Questions

Answers to Your Most Common Questions

What is the difference between lab grown diamond and moissanite in an old cut ring?

Lab grown diamond is carbon-based, rated 10 Mohs, IGI/GIA certified. Moissanite is silicon carbide, rated 9.25, with higher fire and a lower price per carat.

Is moissanite a good stone for old cut engagement rings?

Yes. Moissanite's higher fire works well in old cut faceting, producing wide colour movement under soft indoor light.

Are old cut lab grown diamonds more expensive than moissanite?

Yes. Lab grown old cut diamonds cost more than moissanite for the same carat weight. Moissanite gives a larger stone for the same budget.

What is the difference between old mine cut and old european cut?

Old mine cut is squarish. Old european cut is round. Both available in lab diamond and moissanite at Carat Diamonds.

Can I design a custom old cut ring in lab grown diamond or moissanite?

Yes. Our custom team builds rings to your stone type, size, setting, and metal choice, with the same certification as our collection.
