About this 1.01ct lab-grown cushion diamond

This 1.01ct lab-grown cushion sits in the classic one-carat band, graded D colour (colourless) and IF clarity (flawless or internally-flawless), with a very-good cut grade and certified by IGI LG804624128 or 804624128. Listed at 21 retailers as of October 27, 2026, with prices from $410 to $2,802, a $2,392 spread on the same certified stone. Queensmith lists it at $2,802. Cut grade matters more than carat or clarity for visible brilliance. If you can shift budget toward an Excellent or Ideal cut, do it before chasing higher colour or clarity.
