About this 0.4ct lab-grown round diamond

This 0.4ct lab-grown round sits in the sub-half-carat band, graded J colour (near-colourless) and IF clarity (flawless or internally-flawless), with a top-tier cut grade and certified by IGI LGF5E98599 or F5E98599. Listed at 2 retailers as of October 31, 2026, with prices from ₹42,868 to ₹72,779, a ₹29,911 spread on the same certified stone. 18carati lists it at ₹72,779. Flawless clarity in sub-one-carat stones is rarely visible to the naked eye over VS1, so you are paying a meaningful premium for grade rather than appearance.
