About this 0.71ct lab-grown radiant diamond

This 0.71ct lab-grown radiant sits in the half to three-quarter carat band, graded D colour (colourless) and IF clarity (flawless or internally-flawless), with a top-tier cut grade and certified by IGI LG800663214 or 800663214. Listed at 15 retailers as of November 3, 2026, with prices from £151 to £818, a £667 spread on the same certified stone. Michael Trio lists it at £818. 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.
