About this 0.63ct lab-grown cushion diamond

This 0.63ct 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 LG656403251 or 656403251. Listed at 16 retailers as of October 30, 2026, with prices from $337 to $2,500, a $2,163 spread on the same certified stone. Do Amore Diamonds lists it at $2,500. 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.
