Collection: Diamonds
Exclusive Diamonds with GIA Certificate – Handpicked Quality & Transparency
Purchasing a diamond is a decision for eternity, whether as the sparkling centerpiece of an engagement ring or as a valuable investment. Our assortment exclusively features handpicked diamonds that undergo the strictest quality controls and are invariably supplied with an internationally recognized GIA certificate (Gemological Institute of America). This guarantees you maximum security and an objective evaluation of your gemstone at excellent conditions.
The Quality Criteria: What Truly Makes Your Diamond Valuable
To find the perfect stone, it's essential to understand the technical details and terminology. Evaluation is usually based on the famous "4Cs," but for connoisseurs and perfectionists, the criteria extend far beyond that. Here, we explain what matters in our first-class pieces:
Shape: The shape determines the external appearance. The classic "Round Brilliant" cut is the favorite, as it optimally reflects incoming light and provides maximum fire.
Weight (Carat): The carat weight indicates the size of the stone. A brilliant with, for example, 0.59 carats offers an impressive presence while maintaining the perfect balance between exclusivity and everyday wearability.
Color: The color scale ranges from D (finest white) to Z (tinted). A stone with an F rating belongs to the "fine white" category and appears absolutely colorless and pure to the naked eye.
Clarity: This characteristic describes internal features. An IF (Internally Flawless) rating means that the diamond is loupe-clean – even under ten times magnification, no internal inclusions are visible.
Cut, Polish, Symmetry: These three factors determine the sparkle. We rely on the "Triple Excellent" (EX/EX/EX) rating. An excellent cut, perfect polish, and ideal symmetry ensure that light is reflected without loss.
Fluorescence: Some diamonds glow under UV light. A value like "M" (Medium) can give the stone additional vibrancy in daylight without affecting transparency.
Certification & Security: Every one of our pieces is GIA-certified. The certificate number is subtly engraved on the girdle (the edge of the stone) of many of our stones using state-of-the-art laser technology, which unequivocally confirms its identity.
Proportions (Table & Depth): The table and total depth define the geometry. Values around 57% table and approx. 61.8% depth are considered ideal for perfectly unleashing the brilliance of a round cut.
Clarity Details (Inclusions & Milky): We pay attention to details such as BT0, BC0 (no black inclusions) and WT0/WC0 (no white inclusions in the table or crown). Furthermore, with the value M0, we guarantee that the stone is not "Milky" (cloudy) but exhibits crystal-clear transparency.
