About this 0.81ct lab-grown heart diamond

This 0.81ct lab-grown heart sits in the just-under-one-carat band, graded D colour (colourless) and IF clarity (flawless or internally-flawless), with a top-tier cut grade and certified by IGI LG808614276 or 808614276. Listed at 20 retailers as of November 4, 2026, with prices from £216 to £1,099, a £883 spread on the same certified stone. Reve Diamonds lists it at £1,099. 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.
