About this 0.81ct lab-grown radiant diamond

This 0.81ct lab-grown radiant 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 LG731517068 or 731517068. Listed at 14 retailers as of October 30, 2026. 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.
