| Brilliance to the eye | Identical | Identical |
| Certification | IGI (same 4C) | GIA (same 4C) |
| Price at equal carat | 30 to 60% less | Market reference |
| Rarity | Grown in a laboratory | Rare geological formation |

Our recommendation: lab-grown diamond
At the same budget, an IGI-certified lab-grown diamond often means a stone 30 to 50% larger or purer, with brilliance indistinguishable to the naked eye. It is the logical choice for maximum visual impact.
It is not cubic zirconia or moissanite: it is diamond, certified with the same 4C criteria.
An excellent cut creates the fire. Clarity invisible to the naked eye is never seen on the finger.
We show both options side by side, certificates in hand, and the decision is yours.
