About this 0.96ct lab-grown heart diamond

This 0.96ct lab-grown heart sits in the just-under-one-carat band, graded E colour (colourless) and IF clarity (flawless or internally-flawless), with a top-tier cut grade and certified by IGI LG631454187 or 631454187. Listed at 7 retailers as of October 29, 2026, with prices from £339 to £1,131, a £792 spread on the same certified stone. MOH London lists it at £1,131. 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.
