About this 0.71ct lab-grown round diamond

This 0.71ct lab-grown round sits in the half to three-quarter carat band, graded E colour (colourless) and IF clarity (flawless or internally-flawless), with a top-tier cut grade and certified by IGI LG851604567 or 851604567. Listed at 10 retailers as of October 30, 2026, with prices from £114 to £742, a £628 spread on the same certified stone. Reve Diamonds lists it at £742. 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.
