The Language of Quality
The 4Cs
Cut
The most important C — how well a diamond’s facets interact with light. Ideal and Excellent cuts maximize brilliance and fire. At OENLI every round stone is ideal-cut, and fancy shapes are selected for superior proportions.
Color
The absence of body color, graded D (colorless) to Z (light yellow). OENLI stocks D–H color — the whitest, most valuable grades.
Clarity
The absence of inclusions, graded from Flawless to Included. OENLI stones range VVS1–VS2 — eye-clean and brilliant.
Carat
Weight, not size. One carat equals 0.2 grams. Because lab-grown diamonds cost less, your budget buys a larger carat weight at the same quality.
