This 1.04ct lab-grown cushion sits in the classic one-carat band, graded D colour (colourless) and IF clarity (flawless or internally-flawless), with a standard cut grade and certified by IGI LG831696647 or 831696647. Listed at 14 retailers as of October 30, 2026, with prices from $495 to $1,681, a $1,186 spread on the same certified stone. Helzberg Diamonds lists it at $1,681. 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.
