The reason, nevertheless, is much more difficult than simply age. The time period ‘minimize’ describes each the form of a diamond and the symmetry, proportion, and polish of its aspects. On this case, the good minimize and outdated mine minimize each seek advice from the symmetry and proportions minimize right into a diamond.
The Historical past of the Previous Mine Reduce
The outdated mine type of slicing diamonds has been in use for the reason that finish of the seventeenth century. The cuts have been launched as a way to give an added “sparkle” to the diamonds as a substitute of merely refracting the sunshine.
Many of the outdated mine minimize diamonds that exist at present are set inside vintage jewellery from the Georgian, Victorian, and Edwardian eras.
As shall be talked about, the outdated mine minimize is the direct predecessor of brilliant-cut diamonds, first created in 1919 by Marcel Tolkowsky. The Previous European minimize is the bridge between the old-mine diamond and the trendy good diamond.
The development in expertise (and industrial revolution) was a direct reason behind the fast advancing of diamond slicing methods.
Bodily Variations Between Previous Mine and Sensible Reduce
The outdated mine and good cuts have many notable variations in each a part of a diamond. The related elements of a diamond embrace the desk, culet, crown, girdle, and pavilion.
The desk is the highest side of a diamond. It is without doubt one of the greatest methods to distinguish between good cuts and outdated mine cuts. In good minimize diamonds, the desk is 53% – 64% p.c of the girdle diameter. In outdated mine cuts the desk is 38% – 45% of the diameter.
The culet is the diamond’s backside side and is the quickest approach to establish vintage vs trendy diamond cuts.
When the outdated mine minimize was created, expertise wasn’t superior sufficient to create an actual pointed tip on the backside of the diamond. As an alternative, the culet was left as a wider platform, parallel to the desk. In good minimize diamonds, your complete diamond is mapped in a specialised machine to find out its form earlier than slicing begins. The culet is formed on a slicing wheel and appears invisible to the bare eye.
The crown of the diamond is the angled portion between the desk and the girdle. In outdated mine minimize diamonds, the crown is historically angled at 40 levels or better. Fashionable diamonds have a great angle of 34 levels. When inspecting the outdated mine minimize diamond, it should look like lots taller than the trendy minimize diamond.
The girdle is the slim area that dividing the crown and the pavilion. In vintage diamonds, the girdle is often a lot thicker than what’s widespread these days. It was widespread for diamond cutters to go away a single, steady, unpolished floor across the stone. The bruting machine, invented within the Nineties allowed jewelers to side and polish diamonds.
Even till the Thirties, although, most girdles have been left bruted, unpolished and unfaceted.

The pavilion is the slanted space that runs from the girdle to the underside of the diamond. In good minimize stones, the best angle is 42 p.c of the diamond top. This share creates a really quick, squat stone and much more inside brilliance. In outdated mine diamonds, the pavilion is far deeper.
Diamond slicing has developed from hand-operated instruments to at present’s handy imaging and automatic slicing tables. Nonetheless, diamond slicing depends on the expertise and ability of the diamond cutter. It’s nonetheless a really tough and exacting craft.
No two cuts have been an identical in vintage diamonds. As we speak, nevertheless, there are established requirements to maximise the brilliance of every stone. Despite the fact that each old-mine minimize diamonds and good minimize diamonds have the identical quantity of aspects, trendy jewelers and cutters have higher instruments. They’re able to create exact traces and angles to maximise the brilliance of every stone.
Apart from the technical variations listed above, there are lots of subjective variations folks contemplate when buying a diamond. Previous-mine fanatics will often describe the outdated mine minimize diamond as fiery and heat. Some clarify that as a result of the trendy diamond is designed for optimum brilliance, the outdated mine retains a livelier interior gentle.
One other crucial aspect is age and rarity. There are numerous, trendy, good diamonds in circulation, however solely a handful of outdated mine diamonds can be found.

An even bigger difficulty with outdated European minimize diamonds than whether or not they’re completely spherical or not is the slicing of the aspects. Due to the truth that hand-cutting was nonetheless the predominant technique used, aspects are sometimes irregularly formed and fairly a manner faraway from the proper symmetry we see in diamond slicing at present.
For all of the “faults” of an outdated European minimize diamond that we’ve talked about, it’s these variations that make every stone distinctive and which all add to the enchantment of vintage diamonds.
