About this 0.9ct lab-grown round diamond

This 0.9ct 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 LG704591593 or 704591593. Listed at 23 retailers as of October 29, 2026, with prices from £125 to £901, a £776 spread on the same certified stone. Brilliant Earth lists it at £901. 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.
