Certified standards
The 4Cs Diamond Grading Standards
Every diamond selected for our custom rings meets strict expert specifications. Here is how we grade each characteristic.
Excellent to Ideal Cut
The cut determines a diamond's brilliance, fire, and scintillation. It is the most critical factor of the 4Cs.
We craft our rings exclusively with Excellent to Ideal Cut stones. This ensures maximum light refraction, giving the center diamond its characteristic intense sparkle that reflects from across a room.
- Proportions: Cut to exact mathematical angles to return maximum light to the eye.
- Symmetry: Perfect facets alignment for a balanced, harmonious reflection pattern.
- Polish: Smooth mirror-like surface finish preventing any light diffusion.
GIA / IGI Standard
D-F Colorless Grading
Color refers to the presence or absence of trace tint within the diamond, graded from D (colorless) to Z (light yellow).
Our lab-grown diamonds are graded in the elite D, E, and F colorless range. To the naked eye, these stones are completely ice-white, ensuring that your ring reflects pure light without any distracting warm or yellow hues.
- D Grade: Completely colorless. The absolute highest tier of diamond purity.
- E-F Grade: Colorless. Traces of color are invisible except under microscope comparisons.
- Setting Match: Colorless stones look exceptionally brilliant set in white gold or platinum claws.
Colorless Range
D-F represents the premium colorless bracket certified by GIA/IGI.
VS1 to VS2 Clarity
Clarity measures the purity of the diamond, observing microscopic inclusions inside the stone or blemishes on the surface.
We offer VS1 to VS2 (Very Slightly Included) diamonds. These stones are guaranteed to be 100% "eye-clean" — meaning any minor microscopic inclusions are completely invisible to the naked eye under normal viewing conditions.
- Eye-Clean Guarantee: No visible spots, clouds, or feathers. Pure crystal look.
- Light Transmission: Clear paths for light rays, preventing any loss of luster.
- Value Optimization: VS grades provide the perfect intersection of absolute visual purity and optimal value.
Eye Clean Standard
VS1-VS2 represents microscopic inclusions only; completely eye-clean.
Precision Carat Scaling
Carat measures the physical weight of the diamond. 1.0 carat is equivalent to 200 milligrams.
We configuration-scale our rings to maintain perfect design proportions across all carat sizes (from 1.0 ct up to 8.0 ct). As the center stone increases, the accent diamonds in the hidden halo are adjusted in scale to keep the ring looking balanced.
- Millimeter Equivalence: Carat is weight, but shape affects measurements. For example, a 1.0 ct round diamond is approx. 6.5mm in diameter.
- Proportional Accents: Accent weight updates automatically based on the center stone to preserve geometry.
- True-to-life Simulator: Use our carat visualizer slider above to see real finger dimensions.
Proportional Scales
1.0 ct (6.5mm)
2.0 ct (8.2mm)
