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 LG838658444 or 838658444. Listed at 16 retailers as of October 29, 2026, with prices from £139 to £1,337, a £1,198 spread on the same certified stone. Do Amore Diamonds lists it at £1,337. 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.
