About this 0.51ct lab-grown round diamond

This 0.51ct lab-grown round sits in the half to three-quarter carat band, graded G colour (near-colourless) and IF clarity (flawless or internally-flawless), with a top-tier cut grade and certified by IGI LG639449053 or 639449053. Listed at 18 retailers as of October 26, 2026, with prices from €107 to €1,117, a €1,010 spread on the same certified stone. MOH London lists it at €1,117. 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.
