Only when the light is irradiated perpendicularly to the table, the fire produced by the small crown facets is the strongest, and the strength of the fire is affected by the relative size of the table and small crown facets, as well as the angle of the crown. Apparently, the intensity of the fire displayed varies with the cut ratio of the diamond.

The fire produced by the crown facets is strongest only when the light is irradiated perpendicularly to the table. Apparently, the intensity of the fire displayed varies with the cut ratio of the diamond.
The smaller the proportion of the table surface of a round brilliant cut diamond, the larger the area occupied by the inclined facets, and the stronger the fire. However, if the table is small enough, the fire will no longer be strengthened. , the fire will also be damaged.
In general, smaller decks produce more fire but lose some brightness; larger decks produce more brightness but lose some fire.
Therefore, fire and brightness are trade-offs, and there is no kind of fire and brightness of any cut diamond that can reach the maximum at the same time.
Therefore, when different countries and regions target diamonds with different cut proportions, they will have their own "ideal proportions" because of their different preferences for fire and brightness. One of the differences in these proportions is the relative size of the table and crown facets, as well as the variation in the size of the crown angles.
The quality of the cut will have a great impact on the color, clarity and weight of the diamond. Good cutting can make the shape, size, proportion of each part, cutting angle, symmetry, color, optical effect, weight and other aspects meet the ideal requirements, so that the light passing through the diamond will undergo total internal reflection, from the diamond The top of the scatter, "fire" is the best.

Why Are Large-Size Single-Crystal Diamond Heat Sinks Manufactured Using a Mosaic Assembly Process?
In the packaging design of 5G RF power amplifiers, automotive VCSEL radars, high-performance AI chips, and high-power industrial lasers, large-area single-crystal diamond heat sinks measuring 35 mm or larger are an essential requirement. Most procurement and thermal design engineers ask the same question: Why do 25×25 mm single-crystal heat sinks on the market tend to use a mosaic assembly structure? This is not due to a simplification of manufacturing processes, but rather because of unavoidabl

CVD Diamond: Growing Diamonds for the Future
When people talk about diamonds, the first thing that comes to mind is usually luxury jewelry. But today, diamond is becoming much more than a gemstone. With the rapid development of AI, semiconductors, 5G, and high-power electronics, diamond is attracting attention as an advanced material because of its exceptional thermal properties.

What Are Treated Diamonds? From Technology, Differences to Identification
In the diamond consumer market, one question is being asked by more and more buyers: "Is the colour of this diamond natural, or has it been treated?" So what exactly is a treated diamond? How is it "treated"? And how can consumers identify and judge it?

The Metamorphosis of Diamond: From Jewelry to a Cornerstone of Technology—Three Key High-Tech Applications of CVD Single-Crystal Diamond Wafers
When you hear the word "diamond," what comes to mind first? Is it dazzling diamond jewelry, or the romantic vow that "a diamond is forever"? In reality, diamond is making a major breakthrough in the realms of industry and technology—demonstrating its value in a truly "hardcore" way. Thanks to its status as the hardest material in nature, its exceptional thermal conductivity, and its broad optical transparency (spanning from ultraviolet to infrared), CVD (Chemical Vapor Deposition) single-crystal
