1.What is an Old European-Cut Diamond?

An Old European cut diamond (also called an Old Euro cut diamond) is a round-cut diamond that was cut between 1890 and 1930. Most Old European cut diamonds at that time were hand cut and polished because there were none of the modern machines and technology we have today. Old European cut diamonds mainly rely on candlelight as a light source, through the diamond table and pavilion to maximize the light of the candle to make the diamond more shining.

2.Old European Cut Diamond vs. Brilliant Cut Diamond


The old European cut is earlier than the bright cut, and the biggest similarity between the two cuts is the same number of facets; Each Old European cut and bright cut diamond has 58 facets, and the different places have the following aspects:

  • Fire vs Sparkle

    Because the section of the old European cut diamond is much larger than the bright cut, the old European cut diamond can emit colorful light from the inside, forming a "flame" Angle of view, and the bright cut diamond section is small, the reflected light will be brighter, forming a "spark" Angle of view.

  • Hand-Crafted vs Machine-Cut

Old European cut diamonds were made by hand, while modern bright cut diamonds are machine cut. Some of the old European cuts are irregularly shaped, have strange bumps or have asymmetrical faces. In modern cuts, the cuts are more uniform, although their angles are different, and not all are perfectly round, but there are no obvious raised or asymmetrical faces.

Although the old European cut does not have the symmetry of the bright cut diamond, the old European cut diamond is valued for its uniqueness.
