About this 0.43ct lab-grown round diamond

This 0.43ct 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 LGF5F69854 or F5F69854. Listed at 2 retailers as of October 31, 2026, with prices from $485 to $809, a $324 spread on the same certified stone. 18carati lists it at $809. 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.
