TL;DR: A diamond's cutting style gives a genuine, rough indication of era — point and table cuts suggest pre-17th century, Peruzzi and Old Mine suggest 18th to early 19th century, Old European suggests late 19th to early 20th century, and the modern round brilliant suggests post-1920s. It's a useful starting clue, not a precise dating method on its own.
Why Cut Style Is a Genuine (If Rough) Dating Clue
Diamond cutting technology developed in a real, traceable sequence over centuries, which means a stone's facet style tells you roughly when it was cut, even without any other documentation. This isn't precise — cutters in any given era sometimes still worked in older styles, and a stone can be re-cut later in its life — but it's a genuinely useful starting point, particularly when combined with the setting style around it.
A Rough Timeline to Work From
Point and table cuts suggest a genuinely early stone, predating widespread faceting — these are rare enough today that encountering one almost always means a significant antique or museum-quality piece. See our point, table, and Peruzzi cut guide for the detail.
Peruzzi cuts point to the late 17th century onward, the first genuinely brilliant-style cutting.
Old Mine cuts suggest the 18th to mid-19th century — a cushion-like outline with a high crown and large culet, cut to preserve carat weight from the rough rather than maximise brilliance. See our Old Mine and Old European cut guide.
Old European cuts suggest the late 19th to early 20th century — rounder than Old Mine, closer to a modern brilliant, but still showing a visible culet and softer faceting.
The modern round brilliant, with its standardised 57 or 58 facets, dates from roughly the 1920s onward, following Marcel Tolkowsky's influential proportions work published in 1919.
Rose cuts, single cuts, Swiss cuts, and briolettes ran alongside the mainstream timeline above as specific-purpose styles rather than a strict chronological sequence — see our rose cut, single and portrait cut, and Swiss cut guides for when and why each was used.
What Cut Style Can't Tell You on Its Own
A cut style gives you an era, not a precise date, and it doesn't tell you whether a stone has since been re-cut into a more modern style — something that happened often as fashions changed and owners wanted their stones to look more contemporary. Combining the cut style with the setting's metalwork, hallmarks (if present), and any documented provenance gives a much more reliable picture than the stone's facets alone.

Frequently Asked Questions
Can you tell how old a diamond is just from its cut? Roughly, yes — cutting styles developed in a traceable historical sequence, giving a genuine indication of era, though not a precise date, since older styles sometimes persisted and stones are occasionally re-cut later in their life.
What does an Old European cut tell you about a diamond's age? It suggests the stone was cut in the late 19th to early 20th century, before the standardised modern round brilliant became dominant from around the 1920s onward.
