About this 0.42ct lab-grown cushion diamond

This 0.42ct lab-grown cushion sits in the sub-half-carat band, graded D colour (colourless) and IF clarity (flawless or internally-flawless), with a top-tier cut grade and certified by IGI LG727543038 or 727543038. Listed at 13 retailers as of October 30, 2026, with prices from €214 to €1,164, a €950 spread on the same certified stone. Kay Jewelers lists it at €1,164. 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.
