About this 0.71ct lab-grown cushion diamond

This 0.71ct lab-grown cushion 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 LG833683806 or 833683806. Listed at 15 retailers as of November 2, 2026, with prices from £364 to £1,014, a £650 spread on the same certified stone. Riddles Jewelry lists it at £1,014. 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.
