About this 0.65ct lab-grown round diamond

This 0.65ct lab-grown round sits in the half to three-quarter carat band, graded F colour (colourless) and IF clarity (flawless or internally-flawless), with a top-tier cut grade and certified by IGI LG641479639 or 641479639. Listed at 15 retailers as of October 26, 2026, with prices from £90 to £1,052, a £962 spread on the same certified stone. MOH London lists it at £1,052. 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.
