About this 0.83ct lab-grown heart diamond

This 0.83ct 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 LG823628505 or 823628505. Listed at 18 retailers as of October 25, 2026, with prices from £267 to £1,033, a £766 spread on the same certified stone. Reve Diamonds lists it at £1,033. 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.
