A Pledge of Transparency, A Pursuit of Perfection

Clarity

The clarity of a diamond directly impacts its brilliance and fire. Clarity grading, conducted under a 10x magnification, reveals the stone's internal purity. Diamonds with higher clarity have fewer inclusions, allowing for better light refraction and a more dazzling sparkle. In essence, clarity is a crucial metric for assessing a diamond's aesthetic appeal and value.

We believe that every LusLumin brand enthusiast deserves the highest standard of treatment, which is why we adhere to the industry's stringent clarity grading of VVS (Very Very Slightly Included) and above. Each diamond is meticulously evaluated by our team of experts to ensure its near-flawless nature, with no blemishes visible even under 10x magnification.

Symbol of Purity, Presentation of Rarity

Color

The color grading of a diamond is a critical measure of its purity. In diamond assessment, the absence of color—achieved with colorless diamonds—is the most valuable. Only a trained gemologist can discern the subtle differences in color. This "less color, higher grade" international standard ensures the diamond's sense of purity and high value.

Perfection is LusLumin's constant pursuit and commitment, and we strictly require all our diamonds to demand the highest color grade standard – D (Completely Colorless). We want every friend of the brand to derive strength and visual excellence from our creations.

Craftsmanship Par Excellence, the Origin of Luster

Cut

The cut of a diamond is its "second life," determining how effectively it can capture and reflect light, thereby revealing its fiery essence. Achieving an accurate cut requires not only the gem cutter's extensive experience and exceptional skill but also a deep understanding of optical principles.

Each of our diamonds is meticulously designed and cut to ensure optimal optical performance. Our diamonds not only adhere to the "Very Good" to "Excellent" international grading standards but also represent the relentless pursuit of beauty and perfection by our artisans.

Balancing Weight with Aesthetics, Reflecting Value

Carat Weight

Carat weight is a direct reflection of a diamond's size, but it is not the sole criterion for assessing a diamond's value. The appropriate carat weight should be in harmony with the cut, color, and clarity to collectively contribute to the diamond's overall beauty.

We offer diamonds in a range of carat weights, from delicate to luxurious, to cater to the diverse needs of our clients. We ensure that the carat weight of each diamond is aligned with its optical performance and aesthetic value, providing customers with the most suitable options.
