01Our diamonds
Cuts we offer
We source loose diamonds in classic cuts. Tell us what you are looking for: Carat, budget, and occasion, and we will present a selection with certificates and pricing tailored to you.
Princess
Square, modern, and brilliant: often an excellent way to gain more stone for your investment compared to a round brilliant.
Oval
An elongated brilliant cut that appears larger than its weight and creates a slender look on the finger.
Emerald
A step-cut with long, elegant reflections. It demands high Clarity and rewards it with sophisticated light play.
Pear
A teardrop-shaped hybrid of round and marquise: a distinct character for both rings and pendants.
Cushion
Softly rounded corners and large facets offering a romantic, vintage-inspired brilliance.
02Knowledge
The Four Cs
All diamonds are graded by four international criteria. Together they determine the value and which stone is right for you. Use the slider to explore what each criterion means.
The illustration is schematic. Exact gradings are reviewed during the quote process.
Ct
Carat (weight) 1 ct = 0,2 g
One Carat equals 0.2 grams. Prices rise at specific thresholds rather than linearly. A stone just below a whole Carat mark can offer exceptional value.
Cu
Cut (quality) Excellent–Poor
The only one of the Four Cs controlled by man, and the one that affects brilliance most. A well-cut stone can appear both larger and whiter than its grade suggests.
Co
Colour (grade) D–Z
Graded from D–Z. The differences between adjacent grades are often invisible to the naked eye, though they impact the price significantly.
Cl
Clarity (purity) FL–I3
Describes natural inclusions within the stone. Many inclusions are only visible under magnification. Choosing the right Clarity grade is often the smartest way to optimise your budget.
