About this 0.5ct lab-grown round diamond

This 0.5ct lab-grown round sits in the half to three-quarter carat band, graded J colour (near-colourless) and IF clarity (flawless or internally-flawless), with a top-tier cut grade and certified by IGI LG704568721 or 704568721. Listed at 2 retailers as of October 28, 2026, with prices from £342 to £618, a £275 spread on the same certified stone. Yorxs lists it at £618. 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.
