About this 0.5ct lab-grown round diamond

This 0.5ct lab-grown round sits in the half to three-quarter carat band, graded E colour (colourless) and FL clarity (flawless or internally-flawless), with a top-tier cut grade and certified by IGI LG726536201 or 726536201. Listed at 19 retailers as of October 28, 2026, with prices from £116 to £786, a £670 spread on the same certified stone. Reve Diamonds lists it at £786. 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.
