What is the big deal about Ideal Cut diamonds?

Diamonds are gemstones that have dazzled and fascinated us for centuries. Our interest in diamonds never fades, and who can blame us, right? The brilliance and beauty of diamonds are timeless. But lately, have you been paying attention to all the fuss about ‘ideal cut’ diamonds and wondering what it is all about? Is there something incredibly special about ‘ideal cut’ diamonds? Are they truly flawless and of the highest quality? Well, you can find out all about them here! In this article, we will discuss the history, concept, and specialities of the ‘ideal cut’ diamonds!

What are ‘ideal cut’ diamonds?

The term ‘ideal cut’ refers to a diamond cut grade. An ideal cut diamond would be a diamond that has been polished and cut to the highest standards of proportions, symmetry, angles, light reflection, and shine to receive the title. The term is a benchmark for the quality of diamonds and is one of the rarest cuts. Now you might be wondering what ‘cut’ refers to. Well, to put it simply, the term refers to the overall design of a diamond.

The ‘ideal cut’ Diamonds became a thing in the 20th century when the expert gemologist and engineer Marcel Tolkowsky introduced the concept in his 1919 thesis on diamond grinding. Also known as the Tolkowsky Brilliant, the ‘ideal cut’ has created a new benchmark. Here is a list of parameters to qualify as an ‘ideal cut.’

Table size: 52.4% to 57.5% of the diamond's diameter

Crown angle: 33.7-35.8  degrees

Pavilion angle: 40.2-41.25 degrees

Depth: 56.88% to 63.92% 

Symmetry: Excellent or ideal symmetry

Polish: High-quality polish

Girdle: 0.51% to 2.95% Thin to medium thickness

The science of ‘ideal cut’

The science and magic of an ideal cut diamond lie in its ability to refract and reflect light brilliantly. When light enters a diamond, it's split into different colour components, creating dispersion. The Ideal Cut diamond’s specific angles and proportions maximize this effect, producing an extraordinary brilliance that you can't resist. The unparalleled craftsmanship of ‘ideal cut’ diamonds is a quality we can only marvel at. ‘Ideal cut’ diamonds retain their value and are appreciated over time, and only 3-5% of diamonds meet these standards.

Things to consider before buying diamonds

Though ‘ideal cut’ diamonds adhere to the highest quality standards, they are very rare, and diamonds that are not as perfect as the ‘ideal’ ones also make beautiful jewellery. The rarity of the ideal cut also means that they are only available in round cut, so if you prefer a more fancy shape, you won't find it in the ideal cut. So before you choose your diamond, whether it's ideal or not, consider these factors:

Cut: As we discussed before, the cut is a key factor that determines the quality standards of a diamond. Excellent, very good, good, fair, and poor are the GIA cut grades for diamonds. Symmetry, portions, and polish are parameters that are evaluated to decide the cut grade of a diamond. A brilliantly cut diamond will produce the maximum brightness.

Clarity: Clarity is another crucial factor that decides the quality and price of a diamond; it indicates how flawless the diamond is.

Colour: The colour of a diamond is a factor that indicates its rarity and purity. Pure and bright white diamonds are the most rare.

Carat: Carat refers to the weight of a diamond, and one carat equals to 0.20 grams.

Certification: The certification of a diamond is the proof of authenticity, quality, and value. GIA and AGS are the most reputable and widely trusted diamond-grading labs, and if you are buying ideal cut diamonds, definitely pay attention to the certifications.

Fluorescence: The fluorescence refers to the glow emitted by diamonds when they are exposed to UV rays in the sunlight. Around 25–35% of diamonds are said to have some degree of fluorescence, and it is a factor that can alter the appearance of a diamond.

Shape: There are diamonds in various shapes, and as we mentioned before, ideal cut diamonds come in round shapes. Princess, Marquis, Pear, Heart, Oval, Emerald, Cushion, Radiant, and Asscher are some of the other popular diamond shapes.
