About this 0.53ct lab-grown cushion diamond

This 0.53ct lab-grown cushion 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 LG652497181 or 652497181. Listed at 4 retailers as of October 29, 2026, with prices from £294 to £733, a £439 spread on the same certified stone. Riddles Jewelry lists it at £733. 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.
