About this 0.61ct lab-grown round diamond

This 0.61ct 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 LG818621756 or 818621756. Listed at 8 retailers as of October 28, 2026, with prices from £184 to £1,032, a £848 spread on the same certified stone. MOH London lists it at £1,032. 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.
