About this 0.51ct lab-grown round diamond

This 0.51ct lab-grown round sits in the half to three-quarter carat band, graded E colour (colourless) and IF clarity (flawless or internally-flawless), with a top-tier cut grade and certified by IGI LG737566959 or 737566959. Listed at 20 retailers as of October 29, 2026, with prices from €105 to €1,095, a €990 spread on the same certified stone. MOH London lists it at €1,095. 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.
