The round diamond, otherwise known as the brilliant cut diamond, is by far the most popular diamond shape, especially for engagement rings. Round diamonds will usually provide more flexibility when it comes to balancing cut, colour, and clarity grades while still benefiting from outstanding beauty.
Featuring 58 facets throughout the stone, the round diamond's precise symmetry offers a high level of scintillation. The round cut also complements a broad selection of precious metals and settings, from a simple classic ring to more ornate, vintage designs.

The round brilliant is the most popular diamond shape, representing almost 75% of diamonds sold in the engagement ring market. A round brilliant cut diamond has more fire and sparkle than any other cut, as it’s been mathematically developed to deliver exceptional brilliance.
Just like a wedding band, the round diamond symbolises eternal love and renewal. Its seamless shape also evokes thoughts of the sun—a symbol of life, clarity and strength.
Round diamond engagement rings have become an iconic choice for many due to their intrinsic relationship with marriage proposals. It’s versatile circular shape suits all styles and metals too.
For several years, the technology or machinery did not exist for the round cut diamond. However, the invention of the bruting machine towards the end of the 1800s made the brilliant round diamond cut a possibility. Before this, cushion cut diamonds were the most popular choice in Europe.
Another advance came in 1919 with the publication of Marcel Tolkowsky's thesis "Diamond Design: A Study of the Reflection and Refraction of Light in Diamond". Tolkowsky's work described the ideal proportions of a round cut diamond for maximising light return ( brilliance) and dispersion (fire).
His original specifications for a round cut diamond - 53% table, 59.3% depth, 34.50 crown angle, visible culet - have been adopted and improved upon over time. Today, round cut diamonds are as close to perfection as you can get.
Almost all engagement rings are originally designed for round diamonds, so the majority of settings will look amazing with this shape of stone. Options include
GIA developed the definitive diamond color scale or chart in the early 1950s, a time when there were a lot of different and subjective terms in the marketplace for describing a diamond’s color: white, blue white, AAAA, for example.
The GIA scale begins with the letter D, representing colorlessness, and continues with increasing presence of color to the letter Z, representing light yellow, light brown or light gray. The 23 color grades on the GIA Color Scale (or diamond color chart) are subdivided into five subcategories, which are: colorless (D-F); near colorless (G-J); faint (K-M); very light (N-R); and light (S-Z).
Diamond Clarity refers to the inclusions and blimishes.
To understand diamond clarity, we must first understand how diamonds are created. Natural diamonds are the result of carbon exposed to tremendous heat and pressure deep in the earth. This process can result in a variety of internal characteristics called ‘inclusions’ and external characteristics called ‘blemishes.’
Evaluating diamond clarity involves determining the number, size, relief, nature, and position of these characteristics, as well as how these affect the overall appearance of the stone. If you are trying to determine what is the best clarity for a diamond, remember that no diamond is perfectly pure. But the closer it comes to purity, the better its clarity
Achieving the best cut for a diamond reflects in the stone’s final beauty and value.
Diamonds are renowned for their ability to transmit light and sparkle so intensely. We often think of a diamond’s cut as shape (round, heart, oval, marquise, pear), but what diamond cut actually does mean how well a diamond’s facets interact with light. Precise artistry and workmanship are required to fashion a stone so its proportions, symmetry and polish deliver the magnificent return of light only possible in a diamond.
Diamond carat weight measures Diamonds Apparent size.
To put it simply, diamond carat weight measures how much a diamond weighs.
A metric “carat” is defined as 200 milligrams. Each carat is subdivided into 100 ‘points.’ This allows very precise measurements to the hundredth decimal place. A jeweler may describe the weight of a diamond below one carat by its ‘points’ alone. For instance, the jeweler may refer to a diamond that weighs 0.25 carats as a ‘twenty-five pointer.’ Diamond weights greater than one carat are expressed in carats and decimals. A 1.08 carat stone would be described as ‘one point oh eight carats.’
