About this 1.05ct lab-grown cushion diamond

This 1.05ct lab-grown cushion sits in the classic one-carat band, graded D colour (colourless) and VS2 clarity (very-slightly-included), with a standard cut grade and certified by IGI LG620422070 or 620422070. Listed at 13 retailers as of October 30, 2026, with prices from $415 to $2,420, a $2,005 spread on the same certified stone. Do Amore Diamonds lists it at $2,420. 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.
