About this 0.93ct lab-grown heart diamond

This 0.93ct 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 LG635417142 or 635417142. Listed at 10 retailers as of October 30, 2026, with prices from £132 to £1,030, a £898 spread on the same certified stone. Brilliant Earth lists it at £1,030. 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.
