About this 0.5ct lab-grown cushion diamond

This 0.5ct 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 LG667447924 or 667447924. Listed at 19 retailers as of October 30, 2026, with prices from $399 to $3,442, a $3,043 spread on the same certified stone. Do Amore Diamonds lists it at $3,442. 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.
