About this 0.59ct lab-grown radiant diamond

This 0.59ct lab-grown radiant sits in the half to three-quarter carat band, graded E colour (colourless) and IF clarity (flawless or internally-flawless), with a top-tier cut grade and certified by IGI LG644496296 or 644496296. Listed at 19 retailers as of October 27, 2026, with prices from £113 to £778, a £665 spread on the same certified stone. Reve Diamonds lists it at £778. 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.
