Certified standards
Every diamond selected for our custom rings meets strict expert specifications. Here is how we grade each characteristic.
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.
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.
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.
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.
Independent Grading
Every single diamond center stone we offer is independently graded and certified. Natural diamonds are graded by the Gemological Institute of America (GIA), while our lab-grown diamonds are certified by the International Gemological Institute (IGI).
* GIA / IGI certification applies only to natural and lab diamonds over 0.7cts.
