Unveiling the True Beauty: The Art of Precision Diamond Cutting

At MARLII LAB, we believe that discovering the true beauty of a diamond requires the precision of a master cutter. Our team works with diamond experts who use their deep knowledge to bring to life a vision. A perfectly cut diamond displays a beautiful balance of light, symmetry, scintillation, and even a sense of spirituality. While our strict standards may result in a lower raw weight, we prioritize revealing the diamond's authentic beauty through expert cutting and polishing over maximizing profit.


Size Isn't Everything: Quality Trumps Quantity

A diamond's weight is measured in carats, where one carat equals 0.2 grams. Although weight is a factor, it is not the only aspect that defines a diamond's beauty. At MARLII LAB, we believe that the true essence of a diamond lies in the precision of its cut, the clarity of its sparkle, the richness of its color, and the warmth of its weight in the palm of your hand. We carefully select diamonds based on these four corners of perfection, creating magnificent and sophisticated pieces that showcase our love for luster and la dolce vita.


The Story Behind the Sparkle: The Importance of Diamond Clarity

Every diamond has its own unique story, told through its birthmarks. Although these markings add character, they can also hinder a diamond's brilliance. Diamond clarity is evaluated using a grading system, ranging from imperfect to flawless. At MARLII LAB, our gemologists carefully select only the finest diamonds, from flawless to slightly included, ensuring that each stone shines with maximum brilliance.

The Dance of Light: The Allure of Colorless Diamonds

In a world of vibrant colors, nothing compares to the brilliance of a pristine white diamond. Diamonds are graded on a scale from D (the whitest) to Z, based on the amount of yellow tint present. The whiter the diamond, the more it allows light to dance and shine. At MARLII LAB, we settle for nothing less than the top three grades, ensuring that our diamonds exhibit the utmost brilliance, beauty, and the mesmerizing play of light that defines a precious stone.

Diamond Shapes

The shape of a diamond goes beyond contours and cut; instead of the simplicity of aesthetic desire – it calls on the forces of scientific theory and mathematics. The shape of a diamond changes the language of light, the force of the facet, the blaze of brilliance, and takes your breath away with the radiance of fire. At MARLII LAB we are smitten by shape, we understand that each diamond becomes a signature and the silhouette you choose, comes from the depths of how you define yourself. On this journey to finding your heritage ring; the jewel that will be passed down through generations, let us explore the exquisite nature of shape.
