About this 0.78ct lab-grown round diamond

This 0.78ct lab-grown round 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 LG805612174 or 805612174. Listed at 3 retailers as of October 31, 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.
