About this 0.54ct lab-grown heart diamond

This 0.54ct lab-grown heart sits in the half to three-quarter carat band, graded D colour (colourless) and FL clarity (flawless or internally-flawless), with a top-tier cut grade and certified by IGI LG816624952 or 816624952. Listed at 18 retailers as of November 1, 2026, with prices from £227 to £1,062, a £835 spread on the same certified stone. Reve Diamonds lists it at £1,062. 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.
