About this 0.63ct lab-grown round diamond

This 0.63ct 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 LG665414978 or 665414978. Listed at 6 retailers as of October 28, 2026, with prices from £112 to £446, a £334 spread on the same certified stone. Riddles Jewelry lists it at £446. 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.
