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 LGF5F21511 or F5F21511. Listed at 2 retailers as of October 28, 2026, with prices from $451 to $767, a $315 spread on the same certified stone. 18carati lists it at $767. 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.
