About this 0.58ct lab-grown heart diamond

This 0.58ct lab-grown heart sits in the half to three-quarter carat band, graded G colour (near-colourless) and IF clarity (flawless or internally-flawless), with a top-tier cut grade and certified by IGI LG803661181 or 803661181. Listed at 16 retailers as of October 26, 2026, with prices from £210 to £873, a £663 spread on the same certified stone. MOH London lists it at £873. 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.
