THE 4 C'S OF DIAMONDS

Each diamond is evaluated according to the 4 C's
Diamonds have always inspired humanity with their timeless beauty and the promise of eternal permanence. The variety of their shapes and designs is as unique as the moments they elevate. Regardless of their origin, every diamond is judged according to the universal criteria of the 4Cs: carat, color, clarity, and cut.
This guide will walk you through the 4Cs of diamonds and show you how our lab-grown diamonds are stunning in every detail while honoring the earth's heritage. Learn which color and clarity grade is best, which diamond cuts are available, and whether carat really is the only thing that matters.

Choosing a diamond is always a decision of the heart and conscience. Our lab-grown diamonds not only offer unparalleled brilliance and clarity, but also represent a respectful approach to our planet.
Carat - Carat, the measure of weight
Carat has its roots in ancient times. Back then, traders needed a reliable method to determine the weight of gemstones. They chose the seeds of the carob tree, called "keration" in Greek, because of their remarkably uniform size and weight. These small seeds were so reliably similar that they became an early form of a weight standard. Over time, the term "carat" evolved. Today, one carat represents a weight of exactly 0.2 grams. This international standard helps us objectively compare the size of gemstones, although the carat alone doesn't tell the entire story of a diamond. The history of our craft has shown that while carat weight is meaningful, it is not the only characteristic that determines a diamond's value and beauty. We make it a priority that every diamond—large or small—excels not only in its weight, but also in its origin, craftsmanship, and adherence to ethical standards. In our selection of diamonds—from luminous melee diamonds to striking large solitaires—each carat weight not only represents the size and weight of the gemstone, but also a promise of ethical sourcing and environmentally friendly processing.
For round brilliant cuts, we offer a certificate confirming authenticity and quality starting from 0.3 carats, and for fancy cuts, this certification starts from 0.5 carats.
Color - The color or rather the tint
In the diamond world, color is a crucial quality characteristic that largely determines a diamond's aesthetic appeal. A diamond's color is rated using a letter scale that ranges from absolutely colorless diamonds, classified as 'D color,' to stones with slight hues, which are ranked further down the alphabet.
The color scale of diamonds:

Our range includes only diamonds from the highest segment of this scale, DF. Diamonds in categories D, E, and F are nearly or completely colorless. These coveted stones reflect light in its purest form, thus radiating exceptional brilliance. Their colorlessness underscores their rarity and quality, highlighting the craftsmanship with which each diamond was cut to unleash the maximum fire and brilliance. When you choose a diamond from us, you can be assured of receiving a stone of the highest color quality that not only impresses visually but also reflects our commitment to sustainable luxury.
How important is color in diamonds and how does color influence the quality and appearance of a diamond?
The color of a diamond plays a crucial role in determining its overall quality and appearance. Colorless or nearly colorless diamonds are considered particularly valuable because they optimally reflect light, creating exceptional brilliance and intense sparkle. Color influences how vibrant and radiant the diamond appears and can therefore significantly impact the overall appearance of a piece of jewelry. Therefore, we only offer diamonds in the best color categories D to F in our range to ensure that our customers receive jewelry of the highest optical quality and breathtaking beauty.
Clarity - The Purity
A diamond's purity, also known as clarity, is a crucial criterion that defines the uniqueness and quality of each stone. Clarity refers to the presence of inclusions or imperfections in a diamond. These occur during the growth process (in lab-grown diamonds and also in conventionally mined diamonds) and give each stone its own individual character. Most of these inclusions are microscopic and barely visible to the naked eye. These inclusions are like fingerprints: they make each diamond unique. A diamond is classified as "flawless" if it has no visible inclusions under ten times magnification. These flawless stones are extraordinarily rare and therefore particularly valuable.
How important is the clarity of a diamond?
In our collection, we place great importance on the clarity of the diamonds. We offer diamonds that are graded at least VS (Very Small Inclusions) to VVS (Very Very Small Inclusions). This means that inclusions, if present at all, are so small that they are invisible to the naked eye. These minimal imperfections only become visible under 10x magnification, such as with a jeweler's loupe. With such clarity grades, our diamonds guarantee breathtaking clarity and radiance that optimally captures and reflects light. The result is an impressive brilliance and vibrancy of the diamond, which makes every piece of jewelry a real eye-catcher. Choosing a diamond with high clarity is not just a matter of aesthetics, but also a sign of quality. With a diamond from us, you can be confident that you own a piece that impresses both visually and qualitatively.
Cut - The diamond cut
A diamond's cut is crucial to its fire and brilliance. It's not just about the shape, but also the proportions and finish of the stone. A good cut captures and reflects the light at every angle. We offer a selection of precision-cut shapes, including oval, brilliant, and pear, all designed to maximize brilliance and beauty.
Our lab-grown diamonds represent not only modern luxury but also a commitment to a better future. Experience unparalleled brilliance and purity with a clear conscience.
