When it comes to purchasing a diamond, most people consider the "Four Cs" — carat, colour, clarity, and cut. While these factors are certainly important, at H. Sena, we believe in going beyond the basics. Perfect proportions are essential to a diamond’s beauty and brilliance, which is why our selection process includes precise standards for crown angle, table, and depth. Each diamond is meticulously evaluated to enhance light performance and ensure mesmerising sparkle. By adhering to these exacting standards, including classic cuts and Hearts and Arrows, H. Sena offers diamonds of unparalleled brilliance — these perfect proportions are what set our diamonds apart.


Crown Angle: 34-35 Degrees

The crown angle is a critical measurement that influences how light travels through a diamond, affecting its overall sparkle. At H. Sena, we select diamonds with a crown angle between 34 and 35 degrees. This precise angle allows for the perfect balance of light refraction, maximising brilliance and fire. A well-angled crown ensures that the diamond captures and reflects light beautifully, creating that breathtaking sparkle we all desire in a fine gem.


Clarity: Only VS & Above

Clarity is one of the most critical factors in a diamond’s beauty and longevity. Inclusions — internal imperfections — not only affect a diamond’s appearance but can also compromise its structural integrity. At H. Sena, we exclusively select diamonds with VS clarity and above, ensuring they are free from black inclusions, visible imperfections, and weaknesses that can impact durability. Inclusions in lower-graded stones, such as those in SI or I clarity, can create weak points, increasing the risk of chipping or damage over time. By prioritising clarity, we offer diamonds with pristine brilliance and exceptional strength, allowing each stone’s natural beauty and resilience to shine for a lifetime.


Table Size: 56-60%

The "table" of a diamond is the flat, topmost surface, and its size plays an important role in the gem's brilliance. We select diamonds with a table size between 56% and 60%. A table within this range provides a balanced surface area for light to enter and reflect, resulting in a harmonious sparkle. A well-proportioned table also enhances the diamond’s face-up appearance, giving it a larger look and better overall aesthetic.


Depth: 60-62.1%

A diamond's depth percentage is the ratio of the stone's height to its diameter. Depth influences a diamond’s cut and how light passes through it. At H. Sena, we carefully select diamonds with a depth between 60% and 62.1%, ensuring that each stone achieves the ideal balance between brilliance and visual weight. If a diamond is too shallow or too deep, it can lose light through the bottom or sides, resulting in diminished sparkle. By adhering to this depth range, we guarantee that our diamonds maximise light performance and radiance.


No Chips, No Drills

Durability is essential in any fine gemstone. A diamond should be able to withstand the test of time, remaining beautiful through everyday wear. For this reason, we are diligent about choosing diamonds without chips or drilled holes. Chips can weaken the stone and make it more susceptible to further damage, while drilled diamonds often result from attempts to improve clarity artificially, compromising structural integrity. At H. Sena, we believe in preserving a diamond’s natural integrity, offering only stones that are unblemished and ready to stand the test of time.


Hearts and Arrows: The Ultimate Symbol of Precision

In addition to meeting our rigorous quality standards, H. Sena proudly carries and can source Hearts and Arrows diamonds. This specific cut pattern, often found in round brilliant diamonds, showcases a perfectly symmetrical display of hearts and arrows when viewed under magnification. Hearts and Arrows diamonds are renowned for their precision and unparalleled brilliance, achieved only by expert craftsmanship. These diamonds represent the pinnacle of cutting excellence, offering an extraordinary level of symmetry and light performance. For those seeking a diamond that embodies perfection and precision, a Hearts and Arrows diamond is the ultimate choice.
